8 0

Answer:

124

Step-by-step explanation:

14 -22=8

8= the number of students that didn't like playing baseball

Somehow 8 = 800%

if you subtract 800%-308 it gives you -124

124 students don't like playing baseball

What is the amount of money , P, that will generate $40 in interest at a 10% interest rate over 5 years ?
EastWind [94]

Answer:

The amount of money is 60$

Step-by-step explanation:

Given,         Principal, P = $40

                   Rate, R = 10%

                   Time, T = 5 years

We have to calculate the amount A = S.I + P

             S.I =\frac{ P\times R \times T}{100}

⇒           S.I = \frac{40\times 10\times 5}{100}

                          =  20

Hence, Amount = S.I + P

                            = 20 + 40 = 60$

They intersect so therfor PIR=SIM

so therefor 4x+24=7x+3
minus 4x both sides
24=3x+3
minus 3 both sides
21=3x
divide both sides by 3
7=x
x=7

The annual yield per walnut tree is fairly constant at 140 pounds per tree when the number of trees per acre is 20 or fewer. For
Vlad [161]

Answer:

a. To maximize the annual yield for the​ acre the number of walnut to be planted per acre is n = 45

b. the maximum number of pounds of walnuts per​ acre is T = 4,050

Step-by-step explanation:

Let T represent the total number of pounds of walnuts per​ acre and n represent the number of trees per acre.

From the question;

For each additional tree over 20​, the annual yield per tree for all trees on the acre decreases by 2 pounds due to overcrowding

The number of walnut yield per tree can be represented as;

x = 140 - (n-20)2

the total number of pounds of walnuts per​ acre T is;

T = n(x)

T = n(140 - (n-20)2) = 140n - 2n(n-20) = 140n - 2n^2 + 40n

T = 180n - 2n^2

Maximizing T, we will differentiate T.

T is maximum at dT/dn = 0

dT/dn = 180 - 4n = 0

4n = 180

n = 180/4 = 45

Substituting the value of into the equation of T;

T = 180(45) - 2(45^2)

T = 4,050

Therefore,

a. To maximize the annual yield for the​ acre the number of walnut to be planted per acre is n = 45

b. the maximum number of pounds of walnuts per​ acre is T = 4,050

The Greater Pittsburgh Area Chamber of Commerce wants to estimate the mean time workers who are employed in the downtown area sp
Valentin [98]

Answer:

98% Confidence interval:  (31.74,38.4)

Step-by-step explanation:

We are given the following data set:

29, 38, 38, 33, 38, 21, 45, 34, 40, 37, 37, 42, 30, 29, 35

Formula:

\text{Standard Deviation} = \sqrt{\displaystyle\frac{\sum (x_i -\bar{x})^2}{n-1}}  

where x_i are data points, \bar{x} is the mean and n is the number of observations.  

Mean = \displaystyle\frac{\text{Sum of all observations}}{\text{Total number of observation}}

Mean =\displaystyle\frac{526}{15} = 35.07

Sum of squares of differences = 506.93

S.D = \sqrt{\displaystyle\frac{506.93}{14}} = 6.02

98% Confidence interval:  

\bar{x} \pm t_{critical}\displaystyle\frac{s}{\sqrt{n}}  

Putting the values, we get,  

t_{critical}\text{ at degree of freedom 14 and}~\alpha_{0.02} = \pm 2.145  

35.07 \pm 2.145(\frac{6.02}{\sqrt{15}} ) = 35.07 \pm 3.33 = (31.74,38.4)  

Thus, there is 98% confidence that the population mean number of minutes spent traveling by workers is between 31.74 mins and 38.40
