b. $14,640.00
c. $14,627.93
d. $87,655.58

Amount get after 10 year is $14,640

Given information:

Initial amount invested = $12,000

Annual interest rate = 2.2%

Number of year = 10 year

Find:

Amount get after 10 year

Computation:

Amount of interest = Initial amount invested × Annual interest rate × Number of year

Amount of interest = 12,000 × 2.2% × 10

Amount of interest = $2,640

Amount get after 10 year = Initial amount invested + Amount of interest

Amount get after 10 year = 12,000 + 2,640

Amount get after 10 year = $14,640

Answer:

$14,917.30

Step-by-step explanation:Step 1: To calculate your interest rate, you need to know the interest formula I/Pt = r to get your rate. Here,

I = Interest amount paid in a specific time period (month, year etc.)

P = Principle amount (the money before interest)

t = Time period involved

r = Interest rate in decimal

Step 2: Once you put all the values required to calculate your interest rate, you will get your interest rate in decimal. Now, you need to convert the interest rate you got by multiplying it by 100. For example, a decimal like .11 will not help much while figuring out your interest rate. So, if you want to find your interest rate for .11, you have to multiply .11 with 100 (.11 x 100).

Name the slope and one point that is on the linerepresented by the equation: x = -2
A) m = undefined and point (-2,5)
B) m = 0 and point (-2,4)
C) m = undefined and point (5,-2)
D) = zero and point (5,0)

Answers

Answer: Choice A

m = undefined

point (-2,5)

==================================================

Explanation:

The equation x = -2 describes a vertical line in which every point on this line has x coordinate -2. Two points on this line are (-2,0) and (-2,1)

Another point on this line is (-2,5) since this also has x coordinate -2.

------------------

All vertical lines have undefined slope.

Let's pick two points such as (-2,0) and (-2,1) and find the slope through them

m = (y2-y1)/(x2-x1)

m = (1-0)/(-2-(-2))

m = (1-0)/(-2+2)

m = 1/0

m = undefined, since we cannot divide by zero.

the radius of the cone is 1.75 inches, and it’s height is 3.5 inches. If the diameter of the bubble gum ball is 0.5 inches, what is the closest approximation of the volume of the cone that can be filled with flavored ice?

Answers

Explanation:

The volume of a cone is:

V_(c)=(1)/(3)\pi r^2 h \n \n \n Where: \n \n r:\text{Radius of the cone} \n \n h:\text{height of the cone}

Here:

r=1.75in \n \n h=3.5in

So, substituting into the formula:

V_(c)=(1)/(3)\pi (1.75)^2(3.5)\approx 11.22in

The gum ball is spherical. so the volume of a sphere is:

V_(e)=(4)/(3)\pi r^3 \n \n \n Where: \n \n r:\text{Radius of the gum ball} \n \n \n \text{We know that the diameter of this ball is} \ d=0.5in \ \text{so the radius is:} \n \n r=0.5/2=0.25in

Therefore:

V_(e)=(4)/(3)\pi (0.25)^3\approx 0.065

Finally, the volume (V) of the cone that can be filled with flavored ice is:

V=V_(c)-V_(e)=11.22-0.065 \n \n \boxed{V\approx 11.15in^3}

Breyers is a major producer of ice cream and would like to test if the average American consumes more than 17 ounces of ice cream per month.

Answers

Answer:

The conclusion for this hypothesis test would be that the average American consumes less than or equal to 17 ounces of ice cream per month.

Step-by-step explanation:

We are given that Breyers is a major producer of ice cream and would like to test if the average American consumes more than 17 ounces of ice cream per month.

A random sample of 25 Americans was found to consume an average of 19 ounces of ice cream last month. The standard deviation for this sample was 5 ounces.

Let \mu = average ounces of ice cream consumed by American per month

So, Null Hypothesis, H_0 : \mu \leq 17 ounces     {means that the average American consumes less than or equal to 17 ounces of ice cream per month}

Alternate Hypothesis, H_A : \mu > 17 ounces    {means that the average American consumes more than 17 ounces of ice cream per month}

The test statistics that will be used here is One-sample t test statistics as we don't know about population standard deviation;

                                 T.S.  = (\bar X-\mu)/((s)/(√(n) ) )  ~ t_n_-_1

where, \bar X = sample average = 19 ounces

             s = sample standard deviation = 5 ounces

             n = sample of Americans = 25

So, test statistics  =  (19-17)/((5)/(√(25) ) )  ~ t_2_4

                               =  2

The value of the test statistics is 2.

Now at 0.025 significance level, the t table gives critical value of 2.06 at 24 degree of freedom for right-tailed test. Since our test statistics is less than the critical values of t, so we have insufficient evidence to reject our null hypothesis as it will not fall in the rejection region due to which we fail to reject our null hypothesis.

Therefore, we conclude that the the average American consumes less than or equal to 17 ounces of ice cream per month.
