Which of the following is not an integer?

In-s [12.5K]

Answer:

$-\frac{54}{7}$

Step-by-step explanation:

The first number is $\sqrt{\frac{64}{4} }$

We simplify to get: $\sqrt{\frac{64}{4} }=\sqrt{16}=4$

The second number is $-\frac{54}{7}$ .

This number can be rewritten as $7 \frac{5}{7}=7.714285714287$

This is not an integer

The third number is $(\frac{-25}{5})^2$

We simplify to get: $(\frac{-25}{5})^2=(-5)^2=25$

This is also an integer.

The correct answer is $-\frac{54}{7}$ .

Answer:

Option a

Step-by-step explanation:

Given two normal distribution samples

I group has 106 as mean and 8.5 as std deviation with sample size = 60

II group has 121 as mean and 6.3 as std deviation with sample size =38

We find mean difference =-15

For margin of error finding, we have to find the combined std error for the difference

Variance of difference = Sum of variances

STd error for difference = 1.50

Hence for 99% margin of error =2.58(1.50)

= 3.87

Enya is building a storage cupboard in the shape of a rectangular prism. The rectangular prism has a square base with side lengt

Gnesinka [82]

The amount of paint required to paint the whole cupboard is:

$2\times2.5^2+4\times(2.5\times3.5)
\\=47.5 ft^2$

The amount of paint required to paint all but the bottom surface is:

$2.5^2 + 4(2.5\times3.5)
\\= 41.25 ft^2$

So the difference in paint required is 6.25 square feet worth of paint.

Answer:

1344 ft^2

Step-by-step explanation:

From the picture we can see that 4w = 3l, which means that l = (4/3)w. Since w = 12 ft, l = (4/3)(12 ft) = 16 ft. Then the total area of the floor is

(length of floor)(width of floor) = (48 ft)(12 ft + 16 ft) = 1344 ft^2
