t_v= \frac{-b}{2a} =- \frac{15}{2\cdot (-6)} = \frac{15}{12}= \frac{5}{4}=1.25

then 

h( \frac{5}{4} )=-6\cdot  (\frac{5}{4} )^2+15\cdot \frac{5}{4} +2= \frac{91}{8} =11.375

A physician wants to develop criteria for determining whether a patient's pulse rate is atypical, and she wants to determine whe
valkas [14]

Answer:

a) 66.1 < μ < 82.7

b) 71.9 < μ < 97.7

c) D. No, because the two confidence intervals overlap, we cannot conclude that the two population means are different.

Step-by-step explanation:

Confidence interval is given by the formula

M±t×(\frac{s}{\sqrt{N} }) where

  • M is the sample mean
  • t is the corresponding t value for 95 confidence level
  • s is the sample standard deviation
  • N is the sample size

<u>a. Construct a 95% confidence interval estimate of the mean pulse rate for males.</u>

For men:

M=74.4 t=2.262 s=11.6207 N=10 then confidence interval is:

74.4±2.262×(\frac{11.6207}{\sqrt{10 } }) ≈ 74.4±8.3

<u>b. Construct a 95% confidence interval estimate of the mean pulse rate for females.</u>

For women:

M=84.8 t=2.262 s=18.0488 N=10 then confidence interval is:

84.8±2.262×(\frac{18.0488 }{\sqrt{10 } }) ≈ 84.8±12.9

<u>c. Compare the preceding results. Can we conclude that the population means for males and females are different?</u>

Difference of Population means for males and females are not statistically significant, since confidence intervals overlap.

If the bakery sells 322 bagels , how many muffins did they sell?
inna [77]

A Bakery Sells Muffins And Bagels. Each Muffin Costs 2.25 And Each Bagel Costs 1.50 . The Bakery Earns 775.50 From The Sale Of Muffins And Bagels On Saturday.

A. Write An Equation In Standard From The Repressents This Situation. (Ax+By=C)

B. If The Barkey Sells 322 Bagels, How Many Muffins Did They Sell?

Answer:

130 muffins

Step-by-step explanation:

Let A be the costs of each Muffin And B be the cost of each Bagel.

Let x be the Muffins and y be the the Bagel.

Given:

So, the equation is written as.

2.25x+1.50y=775.50---------(1)

Bakery sells 322 Bagels.

We need to find muffins sell.

Solution:

Bakery sells 322 Bagels that means y = 322

Now, we substitute y value in equation 1.

2.25x+1.50\times 322=775.50

Solve the above equation for x.

2.25x+483=775.50

2.25x=775.50-483

2.25x=292.50

x=\frac{292.50}{2.25}

x = 130 muffins

Therefore, the bakery sells 130 muffins.
