The statistical out put of the problem after solving with excel is attached below

therefore the 95% confidence interval from the attached solution will be ( 79.95, 82.62 )

Answer: (79.95, 82.61)

Step-by-step explanation:

Use Excel to calculate the 95% confidence interval, where α=0.05 and n=25.

1. Open Excel and enter the given data in column A. Find the sample mean, x¯, using the AVERAGE function and the sample standard deviation, s, using the STDEV.S function. Thus, the sample mean, rounded to two decimal places, is 81.28 and the sample standard deviation, rounded to two decimal places, is 3.23.

2. Click on any empty cell, enter =CONFIDENCE.T(0.05,3.23,25), and press ENTER.

3. The margin of error, rounded to two decimal places, is 1.33. The confidence interval for the population mean has a lower limit of 81.28−1.33=79.95 and an upper limit of 81.28+1.33=82.61.

Thus, the 95% confidence interval for the mean bounce height of the golf balls is (79.95, 82.61).

The equation that represents the statement is

2y = 100+9x

A linear equation is an algebraic equation where each term has an exponent of 1 and when this equation is graphed, it always results in a straight line. This is the reason why it is named as a 'linear equation.

If x represents the number of years invested and y represents the investment's value.

I = p×r×t/100

I = 50 × 9 × x/100

I = 9x/2

A = P+1

y = 50+ 9x/2

multiply both sides by 2

2y = 100+9x

therefore the equation of the statement is

2y = 100+9x

Answer:

236°

Step-by-step explanation:

The circumference of a circle is 360° since <DOC is given as 44° and <COB is given as 80° and the center angles are equal to the arc it sees the the measure of arc DEB would be 360 - 44 - 80 = 236°

The new office should be at a distance of 37.5 miles from Jonesville.

The weighted mean is the sum of all elements in a data-set multiplied by their weights, divided by the sum of the weights. For example, if x1 and x2 are the elements with weights w1 and w2 respectively, then the weighted average is calculated using the given formula-

M =  {(x1*w1) + (x2*w2)}/ (w1+w2)

Here, we are given that two cities Jonesville and Bellevue, 60 miles apart.

Let Jonesville be at point 0 and Bellevue be at point 60.

Jonesville has a weight of 3 and Bellevue has a weight of 5.

Thus, the weighted average can be calculated as follows-

Mean = {(60*5) + (0*3)}/8

= 300/8

= 75/2

= 37.5

Thus, the new office should be at a distance of 37.5 miles from Jonesville.

Answer:

They ate the same amount of each pie

Step-by-step explanation:

The cherry pie was cut into 6 equal slices and 3 of these slices were eaten so that means there is 1/2 of the pie still left.

The pumpkin pie was cut into 12 equal slices and 6 of these slices were eaten so that also means there is 1/2 of the pie left.

Since both pies still have 1/2 left and they were both the same size then that means the same amount of pie was eaten from both the cherry and the pumpkin.

Answer:

  999 meters

Step-by-step explanation:

The length of the lift line represents the hypotenuse of a right triangle. The side opposite the given angle is the height of the mountain. The applicable trig relation is ...

  Sin = Opposite/Hypotenuse

We want to find the hypotenuse, so we use the rearranged form ...

  hypotenuse = (mountain height)/sin(33°)

  lift length = (544 m)/sin(33°) ≈ 998.83 m

The length of the lift from bottom to top is about 999 meters.

Hello!

(2x+1)/3 + (5x-2)/2

= (19x-4)/6

Answer:

see explanation

Step-by-step explanation:

\(\frac{2x+1}{3}\) + \(\frac{5x-2}{2}\)

we require the denominators of both fractions to be the same value

the LCM of 2 and 3 is 6, so convert both denominators to 6

multiply the numerator/ denominator of the first fraction by 2

multiply the numerator/denominator of second fraction by 3

= \(\frac{2(2x+1)}{3(2)}\) + \(\frac{3(5x-2)}{2(3)}\)

= \(\frac{4x+2}{6}\) + \(\frac{15x-6}{6}\)

now add the numerators, with a common denominator of 6

= \(\frac{4x+2+15x-6}{6}\)

Answer:

73°

Step-by-step explanation:

This equation uses two supplementary angles. Supplementary angles are two angles that add up to 180 degrees.

The triangle has two angles implied, 30 degrees and (180-137) degrees.

(180 - 137) = 43 degrees

Now that we have two angles inside the triangle, we subtract them from 180 to find the last angle.

180 - 43 - 30 = 107

The angle with a measure of 107 degrees and angle 3 are supplementary

180 - 107 = 73 degrees

Step-by-step explanation:

Distributive property of multiplication

The distributive property of multiplication

a(b+c) = a b + a c

(a+b)c = ac + bc

6× (9+8)  = (6× 9) + (6×8)

The product of sum of the expression (2x+1)(5x-8) is  10\(x^2\)-11x-8.

What is product of sum?

Expressions that are a product of sums are Boolean expressions made up of sums of one or more variables, either in their true form or complemented form. Boolean expressions known as "product of sum expressions" are constructed by adding together sums of one or more variables in either their true form, complemented form, or a combination of both.

Here the given expression is ,

=> (2x+1)(5x-8)

=> [2x.5x - 8.2x+5x-8]

=> 10\(x^2\)-16x+5x-8

=> 10\(x^2\)-11x-8.

Hence the product of sum is 10\(x^2\)-11x-8.

The solution that is the closest estimate of the amount of glass Maria will need to construct her pyramid would be =5289.25 cm squared. That is option C.

To calculate the area of a square based pyramid, the formula that should be used would be given below as follows:

\(area = {a}^{2} + 2a \sqrt{ \frac{a2}{4} } + {h}^{2} \)

Where:

a= 44cm

height= 44²-22²= 38.1cm

Area= 44²+ 2(44) × √44²/4 + 38.1²

= 1936+88 × √ 484+1452
