Arturiano [62]

Answer:

Test statistic = -2.44

There is enough evidence to support the strategist's claim.

Step-by-step explanation:

H0 : p = 0.41

H1 : p < 0.41

pˆ = 0.38

Test statistic :

z=pˆ−p/√p(1−p)/n

Z = (0.38 - 0.41) / √(0.41(1 - 0.41) / 1600

Z = - 0.03 / √0.0001511875

Z = - 0.03 / 0.0122958

Z = - 2.4399

Test statistic = -2.44

The Pvalue :

P(Z < -2.44) = 0.0073436

α - level = 0.02

If Pvalue < α ; Reject H0

0.0073436 < 0.02 ; We reject H0

Since Pvalue < α ; Hence, There is enough evidence to support the strategist's claim.

Create a system of equations to represent the word problem. Then solve using the linear combination/elimination method. Show all
Leno4ka [110]

Answer:

Solution given:

model A printers [a] prints=80books per day

model B printers [b] prints=55books per day

total no of printers =9

no of model A printers be x

and

no of model B printers be [9-x]

According to the question;

ax+(9-x)b=670 books

substituting value of a and b; we get

80x+(9-x)55=670

80x-55x+495=670

25x=670-495=175

x=\frac{175}{25}=7

So;

no of model A printers =x=<u>7</u>

no of model B printers =9-x=9-7=<u>2</u>

<u>is</u><u> </u><u>your</u><u> </u><u>answer</u><u>.</u>

Find the value of the expression. 7! ÷ 3! 5,040 5,034 840 24
koban [17]
First, let's review what the "factorial operator"  !   means.

5! = 5*4*3*2*1.

3! = 3*2*1

7! = 7*6*5*4*3*2*1

Then:  

 7!         7*6*5*4*3*2*1       7*6*5*4         5040
----- = ----------------------- = ------------- = ----------- = 5040 (answer) 
 3!              3*2*1                     1                  1

General Formulas and Concepts:

<u>Math</u>

  • Fraction conversions to decimal

<u>Algebra I</u>

  • Reading a Cartesian plane
  • Coordinates (x, y)

Step-by-step explanation:

Where the 2 lines intersect is the solution to the systems of equations.

5/2 would be 2.5 and 4/3 would be approximately 1.333.

Our (x, y) for the graph is (2.405, 1.357), so our answer would be A.
