Find the value of x for which p is parallel to q, if m∠1 = (9x) and m∠3 = 117 .The diagram is not to scale.

kherson [118]

Oh I see sorry . My bad thinking!

m< 1 = m<3 ( corresponding angles) so

9x = 117
x = 117 / 9 = 13

x = 13 Answer

pogonyaev

The graph of f(x) = (0.5)^x is replaced by the graph of g(x) = (0.5)^x − k. If g(x) is obtained by shifting f(x) down by 2 units, the value of k is 2 because g(x)=(.5)x-2. g(x) is f(x) without the "shift" and it said the shift was 2 units, so k is 2

Find a polynomial function that has zeros of -3 and +6

slamgirl [31]

X^2-3x-18
If your zeros are -3 and +6 your factors should be (x+3) and (x-6) then you would multiply it out to get your polynomial which is x^2-3x-18

You are testing the null hypothesis that the population proportion equals .45, using data you collected from a sample of 100 adu

Sedaia [141]

Answer:

$z=\frac{0.3 -0.45}{\sqrt{\frac{0.45(1-0.45)}{100}}}=-3.015$

Step-by-step explanation:

Data given and notation

n=100 represent the random sample taken

$\hat p=0.3$ estimated proportion of interest

$p_o=0.45$ is the value that we want to test

$\alpha$ represent the significance level

z would represent the statistic (variable of interest)

$p_v$ represent the p value (variable of interest)

Concepts and formulas to use

We need to conduct a hypothesis in order to test the claim that the true proportion is 0.45.:

Null hypothesis: $p=0.45$

Alternative hypothesis: $p \neq 0.45$

When we conduct a proportion test we need to use the z statistic, and the is given by:

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

The One-Sample Proportion Test is used to assess whether a population proportion $\hat p$ is significantly different from a hypothesized value $p_o$ .

Calculate the statistic

Since we have all the info requires we can replace in formula (1) like this:

$z=\frac{0.3 -0.45}{\sqrt{\frac{0.45(1-0.45)}{100}}}=-3.015$
