Answer:

100

Step-by-step explanation:

The square root of 10000 can be written as (10000)1/2. Thus,

(10000)^/2 = (100 × 100)^1/2

(10000)^1/2 = [(100)2]^1/2

(10000)^1/2 = (100)^2/2

(10000)^1/2 = (100)^1

So,

√10000 = 100

aleksandrvk [35]

Answer:

The degrees of freedom are given by:

df =n-1= 62 -1=61

And we want to find a critical value on the t distribution with 61 degrees of freedom who accumulates 0.025 of the area on each tail and the critical value would be t_{\alpha/2}= \pm 2.00

And the rejection region would be |t_{calc}| >2.00

Step-by-step explanation:

Data given and notation  

\bar X=10822 represent the sample mean  

s=1741 represent the sample standard deviation

n=62 sample size  

\mu_o =11568 represent the value that we want to test  

\alpha=0.05 represent the significance level for the hypothesis test.  

z would represent the statistic (variable of interest)  

p_v represent the p value for the test (variable of interest)  

State the null and alternative hypotheses.  

We need to conduct a hypothesis in order to check if the true mean differs from 11568, the system of hypothesis would be:  

Null hypothesis:\mu =11568  

Alternative hypothesis:\mu \neq 11568  

The degrees of freedom are given by:

df =n-1= 62 -1=61

And we want to find a critical value on the t distribution with 61 degrees of freedom who accumulates 0.025 of the area on each tail and the critical value would be t_{\alpha/2}= \pm 2.00

And the rejection region would be |t_{calc}| >2.00

an Italian restaurant buys 15 pounds of onions every 2 weeks. how many bags of onions will the restaurant buy in 7 weeks?
Arturiano [62]

Answer:

45

Step-by-step explanation:

This is a trick question. Since they only get three purchases in by 7 weeks, the answer will be 15 times 3 or 45.

(If I'm wrong and it's not a trick question, then it's 15 times 3.5 or 52.5)

Hope this helps!

Luda [366]

A reflection over the y-axis means that "x" will change signs.

A dilation causes the graph to stretch (if the factor is greater than 1) or shrink/compress (if the factor is between 0 and 1). Usually, the instructions will say whether it is a vertical or horizontal stretch (or shrink) so you know which variable is affected. Since it was not specified, I am going to assume that this is both a vertical and a horizontal shrink.

Answer: y = \frac{1}{2}(4^{-2x})
