Ben earns $9 per hour and $6 for each delivery he makes. He wants to earn more then $155 in an 8 hour workday. what is the least number of deliveries he must make to reach his goal?

Answer:

a= g=9.81 m/s square

Mass given to us = 30 kg

Therefore we have to find the acceleration of the object,

As there is no air and mass is irrelevant in free fall, the acceleration the object experiences will be equal to the force of gravity. On our planet, the gravitational pull on an item falling there is approximately:

9.81 m/s square.

Step-by-step explanation:

The equivalent expression by commutative property is,

4g + 13 = 13 + 4g

Commutative property :

According to the commutative property, the numbers we use can be moved around or switched around without changing the result.

a +b =b+a

The given expression is 4g +13

The equivalent expression by the commutative property is

4g +13 = 13 +4g

For g = 10,

4(10) + 13 = 13 + 4(10)

40 +13 = 13 +40

NORAL follows a hyperbolic path.

Equation of hyperbola; x²/6400 + y²/33600 = 1

Given,

The coordinates where the two NAROL transmitters are located = (-200, 0) and (200, 0)

The distance from receiver to these transmitters = 160 miles

We have to find the standard form of the hyperbola that the receiver sits on ;

Here,

The transmitters behave as foci of the hyperbola.

The center of hyperbola; (h, k) = (0, 0)

The distance from center to focal point,

c = 200

Square both sides

c² = 40,000

The distance from the receiver to the transmitters  is given as:

2a = 160

Divide both sides by 2

a = 80

Square both sides

a² = 6400

We have:

b² = c² - a²

This gives

b² = 40000 - 6400

b² = 33600

The equation of a hyperbola is:

(x - h)²/a² + (y - k)²/b² = 1

So, we have:

(x - 0)²/6400 + (y - 0)²/33600 = 1

Therefore,

The equation of the hyperbola is:

x²/6400 + y²/33600 = 1

:) hope it's right:)

Step-by-step explanation:

If a shoe size of 6 is added to the data, there wouldn't be any change in the IQR. Therefore, the correct answer option is: B. the IQR remains a 2.

IQR is an abbreviation for interquartile range and it can be defined as a measure of the middle 50% of data values when they are ordered from lowest to highest.

Mathematically, interquartile range (IQR) is the difference between quartile 1 (Q₁) and quartile 3 (Q₃):

IQR = Q₃ - Q₁

Based on the given data set, the following interquartile ranges was calculated by using Microsoft Excel:

Now, the interquartile range (IQR) is given by:

IQR = Q₃ - Q₁

IQR = 8 - 2

IQR = 2

Adding a shoe size of 6 to the data set, the first and third and interquartile ranges remained the same, which implies that the interquartile range (IQR) would remain as two (2).

Answer:

c is correct.

Step-by-step explanation:

In c, the top equation stays the same.

Multiplying both sides of the bottom equation (3x - y = 4) by 2, we have

6x - 2y = 8.

The expected value is 11.134

The expected value can be calculated as:

EV = ∑xₙ*pₙ

Where xₙ is the n-th outcome. For the case of the spinner we have 2 possible outcomes:

x₁ = 9

x₂ = 4

And pₙ is the probability of the n-th event.

For the case of  each spinner, the probability of each section will be equal to the quotient between the degrees of each arc, and the total number of degrees in a circle (360°).

First, we can see that for outcome = 9, the angle is a right angle, then it is equal to 30°, then the probability of this event will be:

p₁ = 30°/360° = 0.083

And the angle for the second arc must be such that:

30 + A = 360°

A = 360 - 30 = 330

Then the probability for the outcome = 4 is:

p₂ = (330°/360°) = 0.916

Now we can find the expected value as:

EV = (*9 x 0.083 + 4 x 0.916 ) = 11.134

Therefore, the expected value is 11.134

Answer:

A. 18 roses were red.

B. 30 roses were not red.

C. 5/8 were not red.

Step-by-step explanation:

In order to do this question, we first need a calculator. Then, we take three eighths and divide them on the calculator to get:

3 divided by 8 = 0.375.

Then, on the calculator again, we take the 48 roses and find the percentage of the roses that were red, by multiplying it by 0.375:

0.375 x 48 = 18.

A. 18 roses were red.

Now, for the next question, how many roses were not red. We take the 48 roses and subtract it from the roses that were red, which were 18 roses:

48 - 18 = 30.

B. 30 roses were not red.

Now, to find the fraction of the roses that weren't red. We take the 30 roses that weren't red and divide it by the total amount of 48 roses:

30 divided by 48 = 0.625.

In order to make 0.625 into a fraction, we take the higher, but lowest 100th place we can make for 0.625:

625/1,000.

Now, we simplify it:

625 divided by 5 = 125

1,000 divided by 5 = 200

Now, we have 125/200.

Simplify more:

125 divided by 5 = 25

200 divided by 5 = 40

Once more:

25 divided by 5 = 5

40 divided by 5 = 8

Our final fraction is 5/8.

C. The fraction of the roses that were not red are 5/8.

The inequality that can be used to determine the maximum number of days, d, Taylor can afford to rent for while staying within her budget is $37. 93(d) + $0. 11(50) < $300 or d < 7.76.

Inequality is defined as the relationship between non-equal numbers or expressions separated by <, >, ≤, or ≥.

Let d be the maximum number of days Taylor can afford to rent for while staying within her budget.

If a rental car company charges $37. 93 per day to rent a car and $0. 11 for every mile driven, and Taylor plans to drive 50 miles, then it will cost her $37. 93(d) + $0. 11(50).

If she has $300 at most to spend, then the inequality should be d < 7.76

$37. 93(d) + $0. 11(50) < $300

The amount of error that you will accept in the upper tail of the confidence interval as follows

The amount of error that will accept in the upper tail is = 13.97

Amount of error = margin of error

Margin of error = [tex]Z\frac{\alpha }{2} \frac{s}{\sqrt{n} }[/tex]

93% = confidence interval =1- [tex]\alpha[/tex]

=1-.93

=0.07

Hence [tex]\frac{\alpha }{2}[/tex] =0.035

[tex]Z\frac{\alpha }{2} or t\frac{\alpha }{2} = 1.81[/tex]

This problem represents two tail test because a two-tailed test is a method in which the critical area of a distribution is two-sided and tests whether a sample is greater or less than a range of values.

And confidence interval are always two tailed.

So margin of error = [tex]1.81x\frac{1.99}{\sqrt{40} }[/tex]

= 0.57

Upper tail C.I = x + margin of error

=13.4+0.57

=13.97

Lower tail C.I = x - margin of error
