What is an equation for "five more than the
product of 7 and a number t is 10?"

Answer:

Step-by-step explanation:

The area of the rectangular floor is the product of its length and width:

  A = LW = (21 ft)(9 ft) = 189 ft²

The volume of the pod is the product of that floor area and the height:

  V = Bh = (189 ft²)(7 ft) = 1323 ft³

The area of the floor is 189 ft²; the volume of the pod is 1323 ft³.

Answer:

1)77              2)90

Step-by-step explanation:

1)take 11 common

therefore, 11(3.5+1.9+1.6)

               =11(7)

               =77                         (multiply 11 with 7)

2)First solve the numbers in bracket

20 +( 3×11 )+ 5 +( 2×16)

=20+33+5+32

=90

Options :

a mean - 40, median - 50, mode - 60

b. mean-60, median - 50, mode - 40

c. mean - 40, median-60, mode - 50

d. mean - 50, median - 50, mode - 50

Answer: mean - 40, median - 50, mode - 60

Step-by-step explanation: A negatively skewed distribution is characterized by it long tail being positioned to the left(negative direction) with its peak positioned to the right (positive direction) of the distribution. On a general note, the mean is always positioned towards the left or negative side if the peak, with the median coming next and usually positioned to the right of the mean and the mode positioned to the right side of the median.

Hence, for a negatively skewed distribution, the mean has the least value followed by the median, with the mode boasting the highest.

That is : mean < median < mode

Answer:

7.77%(m/m) ; 92.22%(m/m)

Step-by-step explanation:

Given that:

17.5 grams of sugar in 225 grams of an aqueous sugar solution

Percentage by mass of A in a solution (mass percent) = (mass of A / total mass of solution) × 100

Hence,

Percentage by mass of sugar:

= (mass of sugar / total mass of solution) * 100

= (17.5 / 225) × 100

= 0.0777777 × 100 = 7.77%(m/m)

Mass of water(solvent) = (225 - 17.5)g = 207.5g

= (207.5 / 225) × 100

= 0.922222 × 100 = 92.22%(m/m)

Answer:

One brother says of his younger brother: “Two years ago, I was three times as old as my brother was. In three years’ time, I will be twice as old as my brother.” How old are they each now?

Step-by-step explanation:

Let us suppose two years ago my brother's age was x years

Then, my age was 3x

Three years from now, my brother's age will be (x +2+3) = (x+5) years

And my age will be (3x+2+3) = (3x+5) years

But it is given that i will be twice as old as my brother.

So, 2(x+5)= (3x+5)

or, x= 5 years

So my brother's present age is 5+2= 7 years

And my age is 5*3+2= 17 years

The age of the older brother is 13 and the age of the younger brother is 5.

Two simultaneous equations can be determined from this question:

y = 3x - 2 equation 1

y = 2x + 3 equation 2

Where:

y = older brother's age

x = younger brother's age

Equate equation 1 and equation 2

3x - 2 = 2x + 3

Combine similar terms

3x - 2x = 3 + 2

x = 5

Substitute for x in equation 1

3(5) - 2

15 - 2

y =13

Let us consider a data of prevalent diseases.

If the false positive rate is P(Test + | N) = 0.04

Therefore, sensitivity is defined as the probability of a positive test result given the presence of the disease. This can be written as: P (positive test | disease present).

Specificity is defined as the probability of a negative test result given absence of disease, that is, P (negativetest | diseaseabsent). PPV is defined as the probability of the presence of disease given a positive test result, ie, P (disease present | positivetest).

Answer: (-4, -3)

Step-by-step explanation:

The original coordinate of J is (4, -3)

Since it is reflex over y-axis, the y value remains.

For the x value, it is originally 4 units away from the y-axis positively, thus, after reflexing, it will be 4 units away from the y-axis negatively.

The new coordinate of J' is (-4, -3)

[tex] x = \pm \sqrt{19} [/tex]

[tex] x = \pm 4.36 [/tex]

Step-by-step explanation:

[tex] x^2 = 19 [/tex]

[tex] x = \pm \sqrt{19} [/tex]

[tex] x = \pm 4.36 [/tex]

The exact solution is 4.36.

Squares are the numbers, generated after multiplying a value by itself. Whereas square root of a number is value which on getting multiplied by itself gives the original value. Hence, both are vice-versa methods. For example, the square of 2 is 4 and the square root of 4 is 2.

Given:

x² = 19

On taking root on both side

√x² = √19

x= √19

x = 4.3588

Hence, the exact solution and its approximation rounded to two decimal places is 4.36.

Answer:

the probability that the rack ends up in alphabetical order is 0.0001984

Step-by-step explanation:

Given that:

You own 24 CDs. You want to randomly arrange 7 of them in a CD rack.

Th probability that the rack ends up in alphabetical order can be determined by taking note of the permutations and combinations.

From above; all possible permutations of size 7 we can derive from 24 is

24P7

Similarly,we are meant  to estimate  all the possible ways a unique set of 7 things can be gotten from a total of 24

i.e

24 C7

∴

The probability = [tex]\dfrac{^{24}{C}_7}{^{24}{P}_7}[/tex]

= [tex]\dfrac{\dfrac{24!}{7!(24-7)!} }{ \dfrac{24!}{(24-7)!} }[/tex]

=[tex]\dfrac{\dfrac{24!}{7!(17)!} }{ \dfrac{24!}{(17)!} }[/tex]

= [tex]\dfrac{346104}{ 1.74436416 \times 10^9}[/tex]

= 0.0001984

the probability that the rack ends up in alphabetical order is 0.0001984

The probability that the rack ends up in alphabetical order is 0.0001984

The total number of CD is given as:

[tex]\mathbf{n = 24}[/tex]

The number of CDs to select is given as:

[tex]\mathbf{r = 7}[/tex]

The number of arrangement of 7CDs in 24 is represented as 24P7

So, we have:

[tex]\mathbf{^{24}P_7 = \frac{24!}{(24 - 7)!}}[/tex]

[tex]\mathbf{^{24}P_7 = \frac{24!}{17!}}[/tex]

Simplify

[tex]\mathbf{^{24}P_7 =1744364160}[/tex]

The number of selecting 7 CDs from 24 is represented as 24C7

So, we have:

[tex]\mathbf{^{24}C_7 = \frac{24!}{(24 - 7)!7!}}[/tex]

[tex]\mathbf{^{24}C_7 = \frac{24!}{17!!7}}[/tex]

Simplify

[tex]\mathbf{^{24}C_7 =346104}[/tex]

So, the probability is:

[tex]\mathbf{Pr = \frac{346104}{1744364160}}[/tex]

Divide

[tex]\mathbf{Pr = 0.0001984}[/tex]

Answer:

26 and 36.

Step-by-step explanation:

Let the two whole numbers be a and b. Thus, the product of them is 936 while their sum is 62. In equations, this is:

[tex]ab=936\\a+b=62[/tex]

This is a system of equations. To solve, subtract either a or b from the second equation and substitute it into the first.

For instance, subtract b from both sides in the second equation:

[tex]a+b=62\\a=62-b[/tex]

Substitute this into the first equation:

[tex](62-b)(b)=936[/tex]

Distribute:

[tex]62b-b^2=936[/tex]

Rearrange:

[tex]-b^2+62b=936[/tex]

Divide everything by -1 to make the leading coefficient positive:

[tex]b^2-62b=-936[/tex]

Add 936 to both sides:

[tex]b^2-62b+936=0[/tex]

This is now a quadratic. Solve for b.

To do so, we can factor.

After a bit of testing, we can see that -36 and -26 are possible. Thus:

[tex](b-26)(b-36)=0[/tex]

For for b:

[tex]b=26\text{ or } b=36[/tex]

Thus, b is 26 or 36.

Now, plug these back into the isolated equation to solve for a:

[tex]a=62-b\\a=62-(26) \text{ or } a=62-(36)\\a=36\text{ or } a=26[/tex]

It doesn't really matter which one we choose since they're the same.

Thus, the answer is 26 and 36.
