Find x. A. 22 B. 113–√ C. 222–√ D. 113√3

serg [7]

Answer:

x = 31.12

Step-by-step explanation:

First find the base (hypotenuse) of the smaller triangle (the isosceles triangle): Its three sides are 11, 11 and b. b can be found using the Pythagorean Theorem: b^2 = 11^2 + 11^2 = 242. Then b = √242, or b = approximately 15.56.

b (which is approximately 15.56) is the shorter leg of the large (right) triangle. The trig function needed to solve for x is the cosine:

adjacent side

cos 60 degrees = ----------------------

hypotenuse,

15.56

which becomes (1/2) = ------------

Solving this for x, we get: x = 2(15.56) = 31.12

Doing research for insurance rates, it is found that those aged 30 to 49 drive an average of 38.7 miles per day with a standard

Alja [10]

Answer: 0.4302

Step-by-step explanation:

Given : Mean : $\mu=\text{38.7 miles }$

Standard deviation : $\sigma=\text{6.7 miles }$

Sample size : $n=60$

Also, these distances are normally distributed.

Then , the formula to calculate the z-score is given by :-

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

For x=32.5

$\\\\ z=\dfrac{32.5-38.7}{6.7}=-0.925373134\approx-0.93$

For x=40.5

$\\\\ z=\dfrac{40.5-38.7}{6.7}=0.268656\approx0.27$

The p-value = $P(-0.93$

$=P(0.27)-P(-0.93)=0.6064198- 0.1761855=0.4302343\approx0.4302$

Hence, the required probability :-0.4302

One-half the cube of m subtracted by 4 *

Anettt [7]

Answer:

$\frac{m^3}{2} - 4$

Step-by-step explanation:

Required

Determine an expression for the given statement

The expression can be rewritten as:

one-half * the cube of m subtracted by 4

Convert each statement to mathematical expressions:

One half = $\frac{1}{2}$

The cube of m = $m^3$

one-half * the cube of m = $\frac{1}{2} * m^3$

At this stage, we have:

$\frac{1}{2} * m^3$ subtracted by 4

This gives:

$\frac{1}{2} * m^3 - 4$

$\frac{m^3}{2} - 4$

Hence, The corresponding expression is $\frac{m^3}{2} - 4$
