The local grocery store has sorted apples by size. The distribution is approximately normal. The large apples have a mean diamet

er of 10 cm with a standard deviation equal to 0.5 cm. In a bin of 100 large apples, how many can be expected to have a diameter greater than 11.5 cm, three standard deviations above the mean?

Answer:

0

Step-by-step explanation:

Approximately 0.2% of the apples will be more than three standard deviations above the mean size. In a bin of 100 apples, 0.2% of 100=0.2% apples, this rounds down to zero apples that size or larger. (In a bin of 500 apples, there could be one apple of that size.)

Answer:

  B.  F(x) = 2(x -4)² +4

Step-by-step explanation:

The graph opens upward, so has a positive leading coefficient. (Eliminates choices A and C.)

The graph is translated right 4 units, so x in x² has been replaced by (x-4). (Eliminates choice D.)

The transformed graph is of the equation ...

  F(x) = 2(x -4)² +4

Deacon wants to order DVDs. Each DVD costs $12.95, and he must pay a shipping and handling fee of $4.95 for the entire order. De
Aneli [31]

Answer:

12.95x + 4.95 \leq 75

Step-by-step explanation:

Given

Represent number of DVDs with x

Each\ DVD = \$12.95

Handling\ Fee = \$4.95

Budget = \$75 (at most)

Required

Represent as an inequality

If Each\ DVD = \$12.95

x DVD would cost:

x\ DVDs = 12.95 * x

x\ DVDs = 12.95x

So, to make an order of x DVDs, Deacon will pay for

x DVDs and Handling Fee

So:

Payments = 12.95x + 4.95

Recall that his budget is at most $75

This implies that: \leq 75

So, the relationship between his payment and budget is:

12.95x + 4.95 \leq 75

A cone with a diameter of 12 inches has a volume of 640.88 cubic inches. find the height of the cone
BlackZzzverrR [31]

Answer:

The height of the cone is 17\ in

Step-by-step explanation:

we know that

The volume of a cone is equal to

V=\frac{1}{3}\pi r^{2}h

In this problem we have

r=12/2=6\ in ----> the radius is half the diameter

V=640.88\ in^{3}

assume \pi=3.14

substitute the values and solve for h

640.88=\frac{1}{3}(3.14)(6)^{2}h

h=640.88*3/((3.14)(36))=17\ in

PLEASE HELP DUE NOW!!!<br> WILL MARK BRAINLIEST!!!
Ulleksa [173]

Answer: -10, 10

Step-by-step explanation:

first lets add the two equations. add the x's, add the y's, add the constants on the right.

we get

0x - 1y = -10

so then divide --10 by -1 because we do the opposite operations to both sides

and we get y = 10

now substitute y = 10 into the first equation

-10x - 9(10) = 10

and then we get -10x - 90 = 10

now add 90 to both sides

-10x = 100

divide 100 by -10

x = -10

y = 10

checks out
