A side of a square is A = 8^(3/2) inches. Using the area formula A = s2, determine the area of the square.?A = 24 square inches

VLD [36.1K]

Answer:

512 square inches

Step-by-step explanation:

If A = s², and $s=8^{\frac{3}{2}}$ , then

$A=s^2=(8^{\frac{3}{2}})^2$ and

$A=s^2=8^{\frac{6}{2}}$ which simplifies to

$A=s^2=8^3$ which simplifies to

$A=s^2=512$

Therefore, if $A=s^2$ and $s^2=512$ , then

A = 512 square inches

Consider a set of 7500 scores on a national test whose score is known to be distributed normally with a mean of 510 and a standa

german

$\mathbb P(X>600)=\mathbb P\left(\dfrac{X-510}{85}>\dfrac{600-510}{85}\right)=\mathbb P(Z>1.059)\approx0.145$

So approximately 14.5% of the scores are higher than 600. This means in a sample of 7500, one could expect to see $0.145\times7500\approx10.86$ scores above 600.

Help me the questions and answer choices are in the picture

Using the Triangle Inequality Theorem

The sum of two side lengths of a triangle is always greater than the third side

first one: 6, 22 , 10
6 + 22 > 10 : yes
22 + 10 > 6 : yes
6 + 10 > 22 : No because 16 < 22
These 3 lengths could NOT be lengths of sides of a triangle

second one: 8 , 15 , 22
8 + 15 > 22 : yes
15 + 22 > 8 : yes
8 + 22 > 15 : yes
These 3 lengths could be lengths of sides of a triangle

Answer:
Second option
8 cm, 15 cm, 22 cm

deff fn [24]

0.3km=300m
300m:500m
(/100)
3:5
3+5=8
0.3km= 3/8
500m= 5/8
