What is the surface area of the box 12in 4in 3in

1 answer:

5 0

Find the area of the base:
(4)(3) = 12sqft
Find the area of the sides:
(4)(12) = 48sqft
There are 2 bases and 4 sides, therefore:
12(2) + 48(4) = 24 + 192 = 216sqft
Hope this helps :)

the answer would be x=6

to find it you would set 3x-2 equal to 2x+4 and solve because the two sides would be equal if the triangles are congruent

hope this helps :)

Consider a bell-shaped symmetric distribution with mean of 16 and standard deviation of 1.5. Approximately what percentage of da

fredd [130]

Answer: 95.45 %

Step-by-step explanation:

Given : The distribution is bell shaped , then the distribution must be normal distribution.

Mean : $\mu=\ 16$

Standard deviation : $\sigma= 1.5$

The formula to calculate the z-score :-

$z=\dfrac{x-\mu}{\sigma}$

For x = 13

$z=\dfrac{13-16}{1.5}=-2$

For x = 19

$z=\dfrac{19-16}{1.5}=2$

The p-value = $P(-2$

$0.9772498-0.0227501=0.9544997\approx0.9545$

In percent, $0.9545\times100=95.45\%$

Hence, the percentage of data lie between 13 and 19 = 95.45 %

PLEASE HELP I AM SO CONFUSED

soldi70 [24.7K]

Answer:

Option D, 1

Step-by-step explanation:

Step 1: Determine what x1, x2, y1, y2 are

Slope = $\frac{y2 - y1}{x2-x1}$

(x1, y1) is (2, 8)

(x2, y2) is (6, 12)

Step 2: Plug into the formula to get the slope

Slope = $\frac{y2 - y1}{x2-x1}$

Slope = $\frac{12 - 8}{6 - 2}$

Slope = $\frac{4}{4}$

Slope = 1
