The numbers of cookies in a shipment of bags are normally distributed, with a mean of 64
and a standard deviation of 4. What percent of bags of cookies will contain between 60
and 68 cookies?

Answers

Answer 1

Answer:

68% i think yeah?

Answer 2

The percent of bags of cookies will contain between 60 and 68 cookies is 68.29%.

What is standard deviation?

A standard deviation (or σ) is a measure of how dispersed the data is in relation to the mean.

[tex]\mu[/tex]= 64,   [tex]\sigma[/tex]= 4,

[tex]Z_1[/tex]= [tex]X_1[/tex] - [tex]\mu[/tex]/  [tex]\sigma[/tex]

  = 60-64/4

  = -1

again,

[tex]Z_2[/tex]= [tex]X_2[/tex] - [tex]\mu[/tex]/  [tex]\sigma[/tex]

  = 68-64/4

  = 1

Thus, P( 60<X<68)

= p(-1<Z<1)

= 0.6829

= 68.29%

Answer:

Function A < Function B

Step-by-step explanation:

Solving for Function A:

Taking two points: (0,1) and (4,2)

y = mx+c

Substituting (0,1):

1 = 0 + c

c = 1

Substituting (4,2):

2 = 4m+c

Substituting 'c':

2 = 4m + 1

4m = 1

m = 0.25

Comparing slopes (slopes of each - 0.25 and 0.75):

0.75 > 0.25

Hence,

Function A < Function B

Answer: This is a perfect square trinomial. You are trying to find the binomials that multiply to that. In order to do that, you do the following.

Multiply 2x^2 by 4 (A times C)

Find what numbers multiply to give you 8 and add to give you 7.

What is the quadratic function for this graph?

Answers

Answer:

f(x) = (x + 3)² + 2

Step-by-step explanation:

Vertex for of a quadratic function is given by,

f(x) = a(x - h)² + k

Here, (h, k) is the vertex of the parabola.

From the given picture,

(-3, 2) is the vertex of the graph.

Therefore, function will be,

f(x) = a(x + 3)²+ 2

Since, the graph of the function passes through (0, 11),

f(0) = a(0 + 3)²+ 2

11 = 9a + 2

9a = 9

a = 1

Equation of the function,

f(x) = (x + 3)² + 2

the answer is d

Step-by-step explanation:

so for one do y-intercept has to be at (0,25) so we can eliminate answer choices B and C

the reason why it is not a is because a is moving out of constant rate of 25 when it needs to be moving at a constant rate like 10 D is the answer because it's moving at a constant rate of 10 and it has a y intercept of (0,25)

The answer is graph D

What is the present value of an ordinary annuity having semi-annual payments of 8000 for 12 years with an interest rate of 12%compound semi- annually?

Answers

Answer:

PV= $100,402.86

Step-by-step explanation:

To calculate the present value, first, we need to determine the future value using the following formula:

FV= {A*[(1+i)^n-1]}/i

A= semiannual deposit

n=12*2= 24 semesters

i= 0.12/2= 0.06

FV= {8,000*[(1.06^24) - 1]} /  0.06

FV= $406,524.62

Now, the present value:

PV= FV / (1+i)^n

PV= 406,524.62 / 1.06^24

PV= $100,402.86
