find two z values so that the middle 65% of the area is bounded by them

Answers

Answer 1

Answer: Firstly in this question, we need to solve for

α

which is the part of the distribution of which we not looking for.

we can do this with the sum:

α

=

1

0.76

=

0.24

as

0.76

=

76

%

we also know that our Standard Normal Distribution is symmetric, so we must divide that

α

to be split on either side of our distribution. so we solve for:

α

2

=

0.24

2

=

0.12

then we find a correlating

z

-score for the value

0.12

and we get that

z

=

1.175

and

z

=

1.175

This becomes easier to understand when visualized, so observe how we do this sum.

To train for a marathon, Lily plans on running 4 miles per day for the first week and then increasing that daily distance by 1 mile each of the following weeks.

Which of these equations represent the problem.

Answers

The equation which represent the problem is given by an = 4 + 1.00(n - 1)

How to write equation?

Number if miles Lily run per day first week = 4 miles

Additional miles per day each week = 1 mile

let

n = total miles

The equation:

an = 4 + 1.00(n - 1)

When n = week 2

an = 4 + 1(n - 1)

= 4 + 1(2 - 1)

= 4 + 1(1)

= 4 + 1

Answers

Answer: 300 ft^2

Step-by-step explanation:

First, find the area of the rectangle on the bottom:

Area of a rectangle = length * width = 18 * 12 = 216

Now, find the area of the trapezoid:

Area of a trapezoid = (base 1 + base 2) / 2 * height → (10 + 18) / 2 * 6 = 84

Add these together: 216 + 84 = 300 ft^2 :)

if the graph of f(x)=x^2 is shifted 4 units to the left, then what would be the equation of the new graph?​

Step-by-step explanation:

Be careful. You can be confused by shifting left or right because the result is the opposite of what you might think.

f(x) = x^2

Answer:

7 pairs of shoes

Step-by-step explanation:

So your equation is P(x) = -6x² + 60x - 126. This is a parabolic function, and it looks like we can factor it.

First, let's factor out -6 from the equation to simplify it. If we divide each part of the equation by -6, that leaves us with -6(x² - 10x + 21).

Now, we can factor the equation further by finding two numbers that add up to -10 and multiply to get 21. We know that both have to be negative numbers since they add up to a negative number and multiply to a positive one. The numbers you get are -3 and -7, making the equation P(x) = -6(x-3)(x-7).

x = 3 or 7. To maximize profit, you should sell 7 pairs of shoes.

Answers

The amount needed such that when it comes time for retirement, an individual can make semiannual withdrawals in the amount of $15,265 for 35 years is $225093.358.

The total amount to be withdrawn in a year = 15265*2 = $30530

The total amount to be withdrawn in 35 years =$1068550

What is the compound interest?

Compound interest is interest on interest along with interest on the principle.

Annual Rate of interest = 4.5%

Semi-annual rate of interest r=2.25%

Amount A= $1068550

[tex]1068550 =P(1+\frac{2.25}{100})^70[/tex]

[tex]P = $225093.358[/tex]

What is an angle measure?

When two lines or rays intersect at a single point, an angle is created. The vertex is the term for the shared point. An angle measure in geometry is the length of the angle created by two rays or arms meeting at a common vertex.

Given:

Radius is equal to arc length.

To find the measure of the angle at the center:

We have the formula,

Angle in radian = arc length / radius

Let a be the arc length,

then a be the radius.

Substituting the values,

Angle in radian = a/a

Angle in radian = 1 radian

Therefore, 1 is the measure of an angle at the center.

divide both sides by 8

x=14/8

Reduce the fraction;
