ITS EASY PLS HELP !!!

Answer: The answer would be 2 miles a minute.

Step-by-step explanation: Simply divide the miles by the minutes.

Missile's rate of change is 2 mi/ min

The rate of change in this instance is the speed that the missile is going at because rate of change is used to calculate how fast something is changing in respect to time.

Speed = Distance / Time

Distance = 20 miles

Time = 10 minutes

Rate of change:

=  20 / 10

= 2 miles per minute

The rate of change is therefore, 2 mi/ min

Answer:

47 sorry if wrong

Step-by-step explanation:

Answer:

D. 43°

Step-by-step explanation:

Angle CAB = 180° - 133° = 47° (Angles on a Straight Line add up to 180°)

Angle ACB = 180° - 90° = 90° (Angles on a Straight Line add up to 180°)

Angle p or ABC = 180° - 90° - 47° = 43° (Angles in a Triangle add up to 180°)

Problem 18

The x should not be in the denominator. If it was in the denominator, then you wouldn't have a linear equation in the form y = mx+b

Instead, you should have written [tex]y = \frac{1}{17}x+\frac{63}{17}[/tex] or y = (1/17)x + 63/17

Comparing that to y = mx+b form, we see that m = 1/17 is the slope and b = 63/17 is the y intercept.

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

Problem 19

This problem isn't fully shown. The right portion is cut off. I have a feeling the same issue is happening here though. Try moving the x term like mentioned in problem 18. Also, don't forget about the "y=" portion.

The angle measuring 122 degrees is supplementary to the angle next to it.

Supplementary angles are angles that add up to 180 degrees.

180 = ? + 122

Subtract 122 from both sides.

58 = ?

Now we know that the triangle has a 58 degree angle and a 90 degree angle.

58 + 90 + x = 180

Combine like terms.

148 + x = 180

Subtract 148 from both sides.

x = 32 degrees

Answer:

expected gain = $940

Step-by-step explanation:

given data

sale in a certain warehouse = 10 moters

motors sell = $100

probability of defective = 0.03

solution

we get here expected total cost of 1 moter is the sum of product of gain and probabi;ity

EV = $100 × 0.97 + ( -$100 × 0.03)

EV = 94

so expected gain for seller on 10 moter is

expected gain = 10 × $94

expected gain = $940

Answer:

The probability that the paint  latex = 0.857

Step-by-step explanation:

From the given information:

Let consider X to be the event that the customer has purchased the latex paint

Let consider Y to be the event that the customer has purchased semigloss paint.

Now, the probability of X i.e. P(X) = 0.75

SInce X and Y are mutually exhaustive)

P(Y) = 1 - P(X)

P(Y) = 1 - 0.75

P(Y) = 0.25

Similarly, Let Consider Z be the event that the customer has purchased a roller.

We are being told that P(Z|X) = 0.6

P(Z|Y) = 0.30

[tex]P(X|Z) = \dfrac{P(Z|X)(P(X) }{P(Z|X)*P(X)+P(Z|Y)*P(Y)}[/tex]

[tex]P(X|Z) = \dfrac{0.6 \times 0.75 }{(0.6 \times 0.75) +(0.3 \times 0.25)}[/tex]

[tex]P(X|Z) = \dfrac{0.45 }{(0.45) +(0.075)}[/tex]

[tex]P(X|Z) = \dfrac{0.45 }{0.525}[/tex]

[tex]P(X|Z) = 0.857[/tex]

Thus, the probability that the paint  latex = 0.857

The concept of probability is used in order to determine the probability that the paint is latex and the probability is 0.857.

Given :

First, determine the probability that a customer will purchase semigloss paint.

[tex]P(A) = 1- P(B)\\P(A) = 1 - 0.75\\P(A) = 0.25[/tex]

In the above expression P(B) is the probability that a customer will purchase latex paint.

Now, determine the probability that the paint is latex.

[tex]P(B|C) = \dfrac{P(C|B)\times P(B)}{P(C|B)\times P(B)+P(C|A)\times P(A)}[/tex]

Now, substitute the values of all the known terms in the above expression.

[tex]P(B|C) = \dfrac{0.6\times 0.75}{(0.6\times 0.75)+(0.3\times 0.25)}[/tex]

Simplify the below expression.

[tex]P(B|C) = \dfrac{0.45}{(0.45)+(0.075)}[/tex]

[tex]P(B|C) = \dfrac{0.45}{0.525}[/tex]

[tex]P(B|C) = 0.857[/tex]

So, the probability that the paint is latex is 0.857.

Step-by-step explanation:

Close.  You correctly set up the integrals.  When integrating e²ˣ:

∫ e²ˣ dx

½ ∫ 2 e²ˣ dx

½ e²ˣ + C

So the coefficient should be ½, not 2.

[eˣ − ½ e²ˣ]₋₁⁰ + [½ e²ˣ − eˣ]₀¹

[(e⁰ − ½ e⁰) − (e⁻¹ − ½ e⁻²)] + [(½ e² − e) − (½ e⁰ − e⁰)]

1 − ½ − e⁻¹ + ½ e⁻² + ½ e² − e − ½ + 1

-e⁻¹ + ½ e⁻² + ½ e² − e  + 1

Answer:

[tex]\mathrm{Solution: - e + \frac{1}{2e^2}-\frac{1}{e}+\frac{e^2}{2} + 1}[/tex]

Step-by-step explanation:

Your set up for the 'area of the shaded region' is absolutely correct. But when it comes to evaluating them, you are slightly off.

If we break this expression into parts, we have (eˣ - 2e²ˣ)dx on the interval [- 1 to 0] and (e²ˣ - eˣ)dx on the interval [0 to 1]:

(eˣ - 2e²ˣ)dx on the interval [- 1 to 0],

[tex]\mathrm{Apply\:the\:Sum\:Rule}:\quad \int f\left(x\right)\pm g\left(x\right)dx=\int f\left(x\right)dx\pm \int g\left(x\right)dx[/tex]

=> eˣdx - e²ˣdx on the interval [- 1 to 0]

=> [tex]1-\frac{1}{e}-\frac{e^2-1}{2e^2}[/tex]

(e²ˣ - eˣ)dx on the interval [0 to 1],

[tex]\mathrm{Apply\:the\:Sum\:Rule}:\quad \int f\left(x\right)\pm g\left(x\right)dx=\int f\left(x\right)dx\pm \int g\left(x\right)dx[/tex]

=> e²ˣdx - eˣdx on the interval [0 to 1],

=> [tex]\frac{e^2-1}{2}-e+1[/tex]

And now if we add the remaining fractions as expected, we will receive our answer. The set up would be as follows:

[tex]1-\frac{1}{e}-\frac{e^2-1}{2e^2}+\frac{e^2-1}{2}-e+1\\=> - e + \frac{1}{2e^2}-\frac{1}{e}+\frac{e^2}{2}-1 + 2\\=> - e + \frac{1}{2e^2}-\frac{1}{e}+\frac{e^2}{2} + 1\\\\\mathrm{Solution: - e + \frac{1}{2e^2}-\frac{1}{e}+\frac{e^2}{2} + 1}[/tex]

Answer: (total amount paid - $40) / 0.05

Step-by-step explanation:

Given the following :

Monthly fee = $40

Additional fee = $0.05 per minute on phone

Given the the amount paid for the month is available, number of minutes he was on phone can be determined thus :

Total amount to be paid = monthly fee + additional fee

Additional fee = $0.05 × n

Where n = number of minutes on phone

Hence,

Total amount paid = $40 + $0.05n

If the amount paid is known, the number of minutes on phone can be calculated thus;

(Total amount paid - monthly fee) = $0.05n

n = (Total amount paid - monthly fee) / fee per minute on phone

(total amount paid - $40) / 0.05
