Answer:

x > 8

Step-by-step explanation:

When you divide or multiply both sides of an inequality by a negative number, the equality is switched.

-2x + 3 < -13

(-2x + 3) - 3 < -13 - 3

-2x < -16

-2x/-2 < -16/-2

x > 8

Answer:

x > 8

Step-by-step explanation:

In order to solve the inequality for x, we must get x by itself on one side of the equation.

-2x + 3 < -13

3 is being added to -2x. The inverse of addition is subtraction. Subtract 3 from both sides of the equation.

-2x + (3-3) < (-13-3)

-2x < -13 -3

-2x < -16

x is being multiplied by -2. The inverse of multiplication is division. Divide both sides of the equation by -2.

-2x/-2 < -16/-2

When dividing or multiplying by a negative number, remember to flip the inequality sign.

-2x/-2 > -16/-2

x > -16/-2

x > 8

The solution to the inequality is x>8

Answer:

x = 8

Step-by-step explanation:

Let's solve your equation step-by-step.

5x−6=3x+10

Step 1: Subtract 3x from both sides.

5x−6−3x=3x+10−3x

2x−6=10

Step 2: Add 6 to both sides.

2x−6+6=10+6

2x=16

Step 3: Divide both sides by 2.

2x /2 = 16/ 2

x=8

Answer:

So x=8 is the answer.

Step-by-step explanation:

5x-6=3x+10

Adding 6 on both sides to find out the value of x

5x-6+6=3x+10+6

5x=3x+16

Subtracting 3x on both sides to find out the value of x

5x-3x=3x-3x+16

2x=16

Dividing 2on both sides

2x/2=16/2

x=8

Answer:

Step-by-step explanation:

Since the actual probability of having a boy child is 0.51, the probability of having a girl child will be (1 - 0.51) = 0.49

A couple plans to have 3 kids; 2 of whom are boys

(A) Using the binomial model, the probability that 2 of the 3 children will be boys is (2/3) × 0.51 = 0.34

(B) The possible orderings of the 3 children are given below:

B1 B2 G / B1 G B2

B2 B1 G / B2 G B1

G B1 B2 / G B2 B1

Where B1 is one male child and B2 is the other male child

(C)  If we wanted to calculate the probability that a couple who plans to have 8 kids will have 3 boys, briefly describe why the approach from part (b) would be more tedious than the approach from part (a)

If the probability of 2/3 is 0.34 then the probability of 3/8 will be 0.1912 when you cross multiply

There's no following. You need to post a picture or complete the question.

Answer:

The question is incomeplete, below is the completed question

The World Malaria Report (2008) has information on the number of reported malaria cases from 2005–2006 for the ten countries listed in West Africa. The data are presented in the table below:

1. The mean reported West African malaria cases in 2005 is a. less than 116,698. b. greater than 1,600,000. c. 100,000. d. greater than 200,000.

2. The median reported malaria cases in 2006 is a. around 1,000,000. b. less than 200,000. c. 100,000. d. 3,000,000.

3. If the number of reported malaria cases in Sierra Leone were mistyped and reported as 1,160,666, what would happen to the mean and median? a. Both would remain unchanged. b. The mean would change, but the median would stay the same. c. The mean and median would change. d. You cannot tell without doing the actual calculation.

Answer:

The correct answers are:

1. greater than 200,000.  (d)

2. around 1,000,000 (a)

3. The mean and median would change (c)

Step-by-step explanation:

using the data in the attachment to this answer:

1.)The mean is a measure of ecntral tendency, calculated by summing the total of the values and dividing the result by the number of terms. From the data in the 2005 column, only one value is 116,698 and that value is (116,681), the rest of the 9 other values are greater than 116,698 hence option a (less than 116,698) is wrong.

b)Same reason holds for option b (greater than 1,600,000), only one value falls in this category, hence the mean cannot be more than 1,600,000.

c) since the lowest data in the dataset is 116,698, the mean cannot be 100,000, which is less than the lowest data in the dataset

d) The mean is greater than 200,000 because 8 out of 10 (80%) of the values are more than 200,000, hence this is the correct answer.

2) for the median of the 2006 data, let us arrange the values in ascending order:

160,000 266,188 566,450 861,847 1,022,592 1,105,272 1,253,408 1,555,310 2,060,867 3,511,452

For distribution with an even number of terms, the median = (sum of the two middle terms) ÷ 2

Two middle terms are 1,022,592, 1,105,272

Median = (1,022,592 + 1,105,272) ÷ 2

Median = 2127864 ÷ 2

Median = 1, 063, 932

Therefore median is around 1, 000, 000 (a)

3) mistyping the value for Sierra Leone as 1,160,666 instead of 160,666 for 2006, will increase the value by 1,000,000. Both the mean and the median will change, because the value 1,000,000 is a large number compared to the others on the list to cause a change.

Answer:

a

  Yes

b

 [tex]P(1 \& 5) = \frac{1}{36}[/tex]

c

 [tex]P(5 \& 1) = \frac{1}{36}[/tex]

d

 [tex]P(5 \& 1 | 1\& 5 ) = \frac{1}{18}[/tex]

Step-by-step explanation:

From the question we are told that

     Two fair dice, one green and one red were rolled

Generally the  outcomes on the dice independent because the outcome on the first dice is not affected by the second die

Generally the  probability of getting a 1  on a dice rolled is  [tex]P(1) = \frac{1}{6}[/tex]

the  probability of getting a 5 on a dice rolled is  [tex]P(5) = \frac{1}{6}[/tex]

Generally the probability of P(1 on green die and 5 on red die) is mathematically represented as

         [tex]P(1 \& 5) = \frac{1}{6} *\frac{1}{6}[/tex]

         [tex]P(1 \& 5) = \frac{1}{36}[/tex]

Generally the probability of P(5 on green die and 1 on red die) is mathematically represented as

          [tex]P(5 \& 1) = \frac{1}{6} *\frac{1}{6}[/tex]

         [tex]P(5 \& 1) = \frac{1}{36}[/tex]

Generally the probability of P((1 on green die and 5 on red die) or (5 on green die and 1 on red die)) is mathematically represented as

          [tex]P(5 \& 1 | 1\& 5 ) = \frac{1}{36} + \frac{1}{36}[/tex]

         [tex]P(5 \& 1 | 1\& 5 ) = \frac{1}{18}[/tex]

[tex]:\implies\sf\:18=1\times 18[/tex]

[tex]:\implies\sf\:18=2\times 9[/tex]

[tex]:\implies\sf\:18=3\times 6[/tex]

Hence, All the factors of 18 are

Step-by-step explanation:

Given

- [tex]\frac{5}{4}[/tex] x + [tex]\frac{2}{5}[/tex] = - [tex]\frac{13}{30}[/tex]

Multiply through by 60 ( the lcm of 4, 5 and 30) to clear the fractions

- 75x + 24 = - 26 ( subtract 24 from both sides )

- 75x = - 50 ( divide both sides by - 75 )

x = [tex]\frac{-50}{-75}[/tex] = [tex]\frac{2}{3}[/tex]

Step-by-step explanation:

Answer:

17

Step-by-step explanation:

To find the hypotenuse, you would use the Pythagorean theorem.

[tex]A^{2} +B^{2} =C^{2}[/tex]

We can plug 8 and 15 into A and B\

[tex]8^{2} +15^{2} =C^{2}[/tex]

We can simplify this to

64+225=[tex]C^{2}[/tex]

289 = [tex]C^{2}[/tex]

To get C by itself not squared, we can do the square root of both sides.

[tex]\sqrt{289} =\sqrt{C^{2} }[/tex]

If we simplify, we get

17 = C or C = 17

Therefore the length of the hypotenuse is 17.

Answer:

fluid ounces

hope it helps;)

The most likely unit to measure the capacity of a mug is fluid ounces (fl oz).

The maximum amount that something can contain or hold is referred to as its capacity. It is useful for determining the volume of a container, such as a mug or a bucket. Capacity measurement units vary, but common ones include millilitres, litres, fluid ounces, and gallons.

Capacity is a measurement of how much fluid or material a container can hold, and it is usually expressed in ounces, millilitres, litres, or gallons.

Because a mug is a container that holds liquids, the appropriate unit of measurement to use when determining how much liquid a mug can hold is capacity.

Thus, the answer is fluid ounces.

Answer:

l = 26, w = 10

Step-by-step explanation:

These types of word problems always want you to use variables to find the answer. Variables are always going to represent the numbers you don't know.

This question wants you to find the length and width of the wall of the barn, so let's just use l for length (let l = length of barn wall) and w for width (let w = width of barn wall); this is called defining your variables, so that you--or anyone who looks at your work--know what the letter variable represents.

Now we use the other information we have to find what values the variables actually equal.

We know that the length is 6 feet longer than twice the width. To express this in terms of numbers and variables: l = 6 + 2w. This makes sense, right?

length = 6 + (2 * width)

If the total area of the wall is 260 square feet and we need to find the length and width, we can use the A = lw formula, which you can use for any rectangle. Since 260 is the area (A), we can put that into the formula so that we have 260 = lw.

Next, use the expression we came up with earlier (l = 6 + 2w) to help find the answer.

We have two equations now (l = 6 + 2w and 260 = lw) and we just need to put them together.

This part is the same as solving any other linear equation.

The approach I'll use is substitution:

l = 6 + 2w

260 = lw

Substitute 6 + 2w in for l:

260 = (6 + 2w) w

Distribute:

260 = 6w + 2w²

Solve:

w² + 3w - 130 = 0

w = -13, w = 10

(The width of a rectangle cannot be negative, so it has to be 10 ft.)

We're almost there. The last thing to do is to find the length. Just plug in 10 for w in the l = 6 + 2w formula:

l = 6 + 2(10) = 6 + 20 = 26

To check your work, we can double the width and add 6 to get 26, and 26 * 10 is 260.

So, the length of the wall of the barn is 26 and the width of the wall of the barn is 10.

Answer:

5 sandwiches.

Step-by-step explanation:

$15 for the water, $10 for the soda. So if you add 15 and 10 that's 20. 40-25 = 15 on sandwiches. If each sandwich is $3, then that's 5 sandwiches.

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

The number of sandwiches bought is 3.

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

Cost of a bottle = $1.50

Cost of a soda = $2

Cost of a sandwich = $3

Number of bottles bought = 10

Number of sodas bought = 5

Number of sandwiches bought = S

Total amount spend = $40

Now,

10 x 1.50 + 5 x 2 + 3S = 40

Simplify.

15 + 10 + 3S = 40

25 + 3S = 40

Subtract 25 on both sides.

3S = 40 - 25

3S = 15

Divide both sides by 3.

S = 15/3

S = 3

Thus,

The number of sandwiches bought is 3.
