Please help me simplify.

Answer:

32768

Step-by-step explanation:

<h2><u>SIMPLIFY</u></h2>

$\frac{(2^{4} )^5}{2^{5} } \\$

<h3>now make use of the exponent rule :</h3>

$\frac{x^a}{x^b} = x^{a-b}\\$

$(\frac{(2^4)^5}{2^5} = (\frac{2^4}{2} )^5\\$

$\frac{2^4}{2} = 2^3$

= $(2^{3} )^5$

<h3>apply the exponent rule:</h3>

$(a^{b})^c = a^{bc}$

$2^{3*5} \\2^{15}\\$

= <u>32768</u>

In an investigation of pregnancy-induced hypertension, one group of women with this disorder was treated with low-dose aspirin,

AleksandrR [38]

Answer:

Step-by-step explanation:

Given that in an investigation of pregnancy-induced hypertension, one group of women with this disorder was treated with low-dose aspirin, and a second group was given a placebo. A sample consisting of 50 women who received aspirin has mean arterial blood pressure 120mmHg and standard deviation 10mmHg; a sample of 42 women who were given the placebo has mean blood pressure 115mmHg and standard deviation 12mmHg.

Population variances are equal

$H_0: \bar x = \bar y\\H_a: \bar x \neq \bar y$

(two tailed test at 5% significance level)

Here x denotes group I and Y group II

N Mean StDev SE Mean

Sample 1 50 120 10 1.4142

Sample 2 42 115 12 1.8516

Pooled std deviation = 10.9565

df=80

Mean difference= 5

Test statistic t = mean diff/std error = $\frac{5}{2.3299}$ =2.1803

p value = 0.0318

since p <0.05 we reject H0

b) We find p >0.01 hence at 1% significance level we accept H0

This implies that 99% confidence interval contains mean difference =0

How do I find the surface area?

vagabundo [1.1K]

Alright, buckle in because this will be a bit of a bore to listen to.

First, find the areas of all surfaces that you have the length and width of, which i assume you already have.

Next, use the Pythagorean theorem to find the missing measure of that triangle to find the measure of it and the back. make sure to find ALL of the sides, including the ones on the backside of the figure. Too lazy to do it myself, but at least you know how i'd do it.
