A hemispherical bowl of radius 5 inches is filled to a depth of h inches, where 0less than or equalshless than or equals5. Find

mestny [16]

The shape of the water is that of a "spherical cap." The formula for the volume of a spherical cap is ...

... V = π·h²·(r -h/3) . . . . . . . from web search

For a radius of 5 in, this is

... V = π·h²·(5 -h/3) . . . . in³

_____

For h=0

... V = π·0²·(5 -0/3) = 0

For h=5 in

... V = π·(5 in)²·((5 -5/3) in) = (2/3)π·5³ in³ . . . . . the volume of a hemisphere of radius 5

solve 3(2x-1)-10=8=5x l had this question so many times in past 2 weeks in my algebra exams and l still dont know how to solve i

Nat2105 [25]

Alright, so to understand algebra
use PEMDAS
parenthasees
exponents (square roots count as exponents)
multiply or divide
add or subtract

basically try to isolate the unknown/vareable/xterm
so

3(2x-1)-10=8+5x (assuming you meant to type 8+5x and not 8=5x)

first distribute using distributive property
a(b+c)=ab+ac
3(2x-1)=3 times 2x+3 times -1=6x-3
6x-3-10=8+5x
add like terms
6x-13=8+5x
subtract 5x from both sides
x-13=8
add 13 to both sdies
x=21

A salesman of machinery sold 148

USPshnik [31]

Total cost: 148 x 79.5 = 11,766

7% of 11,766 = 11,766 x 7 = 82.362/100 = 823,62

so, his commision was of 823,62

When testing a claim that the majority of adult Americans are against the death penalty for a person convicted of murder, a rand

Black_prince [1.1K]

Using the z-distribution, it is found that the p-value is of 1.

At the null hypothesis, it is tested <u>that the majority is not against the death penalty</u>, that is:

$H_0: p \neq 0.5$

At the alternative hypothesis, it is <u>tested that the majority is against the death penalty</u>, that is:

$H_1: p > 0.5$

The test statistic is given by:

$z = \frac{\overline{p} - p}{\sqrt{\frac{p(1-p)}{n}}}$

In which:

$\overline{p}$ is the sample proportion.

p is the proportion tested at the null hypothesis.

n is the sample size.

In this problem, the parameters are: $\overline{p} = 0.27, p = 0.5, n = 491$ .

Then, the value of the <em>test statistic</em> is:

$z = \frac{\overline{p} - p}{\sqrt{\frac{p(1-p)}{n}}}$

$z = \frac{0.27 - 0.5}{\sqrt{\frac{0.5(0.5)}{491}}}$

$z = -10.19$

Using a z-distribution calculator, for a <u>right-tailed test</u>, as we are testing if the proportion is greater than a value, the p-value is of 1.
