y<-1/2x

y greater than or equal to 2x+3

Answer:

Pretty sure it is A.

Step-by-step explanation:

m4 is equal to m8 because they are same side interior angles and so you set the 2 equations equal to each other to find x. Then plug it in.

Answer:

1.167 gallons

Step-by-step explanation:

Given that:

Fraction of red paint used = 7/10 of a gallon

Fraction of wall painted = 3/5

Gallon of paint required to paint the entire wall:

Fraction of entire wall = 1/1

7/10 paint = 3/5 wall

x paint = 1 wall

Cross multiply

(3/5)x = 7/10

Divide both sides by 3/5

3/5x ÷ 3/5 = 7/10 ÷ 3/5

(3/5)x * 5/3 = 7/10 * 5/3

x = 35 / 30

x = 7/6 = 1.167 gallons of red paint

The null and alternative hypotheses are [tex]H_o[/tex] μ= 64.2 and [tex]H_a[/tex]: μ ≠  64.2 respectively.

In statistics, hypothesis testing is the process by which an analyst tests an assumption about a population's parameter. Using sample data, hypothesis testing is performed to examine the plausibility of a theory.

The average height of an 18-year-old American woman is 64.2 inches

Hypotheses state claims about a population parameter.

p: population proportion: population mean

σ: population standard deviation

The null hypothesis asserts that the sample size equals the claim value:

[tex]H_o[/tex] :μ= 64.2

The alternate hypothesis expresses the inverse of the null hypothesis (As per the claim):

[tex]H_a[/tex] : μ ≠  64.2

μ = The average height of 18-year-old American women in the population.

[tex]H_o[/tex] :μ= 64.2

[tex]H_a[/tex] : μ ≠  64.2

Thus, the null and alternative hypotheses are [tex]H_o[/tex] μ= 64.2 and [tex]H_a[/tex]: μ ≠  64.2 respectively.

Step-by-step explanation:

Answer:

The roots of the equation is real and repeated

Step-by-step explanation:

Here, we want to describe the nature of the roots of the given quadratic equation

To get the nature of the roots, we find the discriminant of the equation

The discriminant is;

b^2 - 4ac

In this case, b = -28 , a = 49 and c = 4

The discriminant is thus;

-28^2 - 4(49)(4)

= 784 - 784 = 0

Since the discriminant is zero, this means that the quadratic equation has real roots which are the same

[tex]\boxed {x = -\frac{8}{9}}[/tex]

Step-by-step explanation:

Solve for the value of [tex]w[/tex]:

[tex]3(3w - 4) = -20[/tex]

-Use Distributive Property:

[tex]3(3w - 4) = -20[/tex]

[tex]9w - 12= -20[/tex]

-Add both sides by [tex]12[/tex]:

[tex]9w - 12 + 12 = -20 + 12[/tex]

[tex]9w = -8[/tex]

-Divide both sides by [tex]9[/tex]:

[tex]\frac{9w}{9} = \frac{-8}{9}[/tex]

[tex]\boxed {x = -\frac{8}{9}}[/tex]

Therefore, the value of [tex]w[/tex] is [tex]-\frac{8}{9}[/tex].

Probability

A standard deck of 52 playing cards has 4 aces.

The probability of getting one of those aces is

[tex]\displaystyle \frac{4}{52}=\frac{1}{13}[/tex]

Now we got an ace, there are 3 more aces out of 51 cards.

The probability of getting one of those aces is

[tex]\displaystyle \frac{3}{51}=\frac{1}{17}[/tex]

Now we have 2 aces out of 50 cards.

The probability of getting one of those aces is

[tex]\displaystyle \frac{2}{50}=\frac{1}{25}[/tex]

Finally, the probability of getting the remaining ace out of the 49 cards is:

[tex]\displaystyle \frac{1}{49}[/tex]

The probability of getting the four consecutive aces is the product of the above-calculated probabilities:

[tex]\displaystyle P= \frac{1}{13}\cdot\frac{1}{17}\cdot\frac{1}{27}\cdot\frac{1}{49}[/tex]

[tex]\displaystyle P= \frac{1}{270,725}[/tex]

P=0.0000037

Step-by-step explanation:

The measures of the angles are 23, 83, and 74 degrees. 97 degrees is not the measure one of the angle measures of the triangle option (B) is correct.

When two lines or rays converge at the same point, the measurement between them is called a "Angle."

It is given that:

The angle measures of a triangle are 2y + 3 degrees, 9y – 7 degrees, and 7y + 4 degrees.

As we know,

The sum of the interior angle of the triangle is 180 degrees

2y + 3 + 9y - 7 + 7y + 4 = 180

18y = 180

y = 10

2y + 3 = 2(10) + 3 = 23 degres

9y - 7 = 9(10) - 7 = 83 degrees

7y + 4 = 7(10) + 4 = 74 degrees

Thus, the measures of the angles are 23, 83, and 74 degrees. 97 degrees is not the measure one of the angle measures of the triangle option (B) is correct.

Answer:

B = 3/4

Step-by-step explanation:

2 1/2 / 3 1/3

can be written as 5/2 divided by 10/3. I always use keep, switch, flip technique with fractions. keep 5/2 switch the division to multiplication, flip the 10/3 to 3/10

5/2 x 3/10 cross multiply

15/20 = 3/4

Answer:

It would be B. 3/4

Step-by-step explanation:

You turn the mixed numbers into improper fractions then you divide by using the reciprocal of the 3 & 1/3. This will leave you into the equation "5/2 * 3/10"

When multiplied, you will get "15/20" which simplifies to "3/4"

you can plug y in for x in the first equation by using substitution

y=-y-4

and then you solve for y

2y=-4

y=-2

so y equals -2. Since y=x, x also equals -2. Therefore
