Answer:

75

Step-by-step explanation:

$12 is 3 times $4, so we can expect to buy 3 times 25 cartons.

You can buy 75 cartons of mostly-melted ice cream for $12.

Let's evaluate the ratio test:

$\dfrac{a_n}{a_{n-1}}=\dfrac{3^{n+1}}{3n+1}\cdot\dfrac{3(n-1)+1}{3^n}=\dfrac{3\cdot3^n}{3n+1}\cdot\dfrac{3n-2}{3^n} = \dfrac{9n-6}{3n+1}$

The limit as $n \to\infty$ of this quantity is 3, which is more than 1. So, the series diverges.

Answer:

95

Step-by-step explanation:

step 1

Find out the total ball bearing ordered

Multiply the number of ball bearing boxes by the number of ball bearings in each box.

$17(85)=1,445\ ball\ bearings$

step 2

Find out the total springs ordered

Multiply the number of spring boxes by the number of springs in each box.

$15(90)=1,350\ springs$

step 3

To find out how many more ball bearings than springs did they order, subtract the total number of springs from the total number of ball bearings

$1,445-1,350=95$

The distribution of a sample of the outside diameters of PVC pipes approximates a normal distribution. The mean is 14.0 inches,

lakkis [162]

Answer:

A. 13.9 and 14.1 inches

See explanation below.

Step-by-step explanation:

Previous concepts

Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".

The Z-score is "a numerical measurement used in statistics of a value's relationship to the mean (average) of a group of values, measured in terms of standard deviations from the mean".

Solution to the problem

Let X the random variable that represent the outside diameters of a population, and for this case we know the distribution for X is given by:

$X \sim N(14,0.1)$

Where $\mu=14$ and $\sigma=0.1$

If we want the middle 68% of the data we need to have on the tails 16% on each one

For this part we want to find a value a, such that we satisfy this condition:

$P(X>a)=0.84$ (a)

$P(X$ (b)

Both conditions are equivalent on this case. We can use the z score again in order to find the value a.

As we can see on the figure attached the z value that satisfy the condition with 0.16 of the area on the left and 0.84 of the area on the right it's z=-0.994. On this case P(Z<-0.994)=0.16 and P(z>-0.994)=0.84

If we use condition (b) from previous we have this:

$P(X$

$P(z$

But we know which value of z satisfy the previous equation so then we can do this:

$z=-0.994$

And if we solve for a we got

$a=14 -0.994*0.1=13.9$

And since the distribution is symmetrical for the upper limit we can use z = 0.994 and we have:

$z=0.994$

And if we solve for a we got

$a=14 +0.994*0.1=14.1$

So the correct answer for this case would be:

A. 13.9 and 14.1 inches
