Answer:
C. 0.077
Step-by-step explanation:
Use binomial probability.
P = nCr pʳ qⁿ⁻ʳ
where n is the number of trials,
r is the number of successes,
p is the probability of success,
and q is the probability of failure (1−p).
n = 10, r = 4, p = 0.64, q = 0.36.
P = ₁₀C₄ (0.64)⁴ (0.36)⁶
P = 210 (0.64)⁴ (0.36)⁶
P = 0.077

The Earth's atmosphere is divided into layers including the troposphere, stratosphere, mesosphere, etc. The troposphere is the layer that is closest to the Earth's surface. The distance from Earth and the troposphere's temperature have a negative association. Interpret the meaning of the negative association with respect to the temperature. As you move closer to the Earth, the temperature decreases. As you move away from the Earth, the temperature increases. As you move closer to the Earth, the temperature remains the same. As you move away from the Earth, the temperature remains the same. As you move away from the Earth, the temperature decreases.

The atmosphere is divided into five different layers, based on temperature.
Which layer of the atmosphere is divided into layers?The graphic below illustrates how the layers of the atmosphere can be separated based on temperature.The troposphere, stratosphere, mesosphere, and thermosphere are those layers.The exosphere is a different zone that starts roughly 500 km above the surface of the Earth. Based on temperature, the atmosphere is separated into five distinct strata.The troposphere, which is located between five and ten miles (or seven and 15 kilometers) above Earth's surface, is the layer that is closest to the surface.The troposphere is significantly thinner near the North and South Poles than it is at the equator. The atmosphere of Earth includes five primary layers and a number of minor ones.The troposphere, stratosphere, mesosphere, thermosphere, and exosphere are the primary layers, in order from lowest to highest.Troposphere.

Answer:
y = -7, y = -3
Step-by-step explanation:
(y - 3)² = 2y² + 4y + 30
expand:
y² - 6y + 9 = 2y² + 4y + 30
subtract 30 from both sides
y² - 6y + 9 - 30= 2y² + 4y + 30 - 30
simplify:
y² - 6y - 21 = 2y² + 4y
subtract 4y from both sides
y² - 6y - 21 -4y = 2y² + 4y - 4y
simplify:
y² - 10y - 21 = 2y²
subtract 2y² from both sides
y² - 10y - 21 - 2y² = 2y² - 2y²
simplify:
-y² - 10y - 21 = 0

Ф = 67.38
tan Ф = 12 / 5
Ф = 67.38
-----------------------
3. find sin β, cos β, tan β
sin β = 4 / 5
β = 53.13
cos β = 3 / 5
β = 53.13
tan β = 4 / 3
β = 53.13
Answer: Step-by-step explanation
2.
cos Ф = 5 / 13 , Ф = 67.38
sin Ф = 12 / 13 , Ф = 67.38
tan Ф = 12 / 5 Ф = 67.38

3) Marvin bought a t shirt that was on sale for 20% off. He paid $14.21. for the t-shirt including
sales tax of 11 percent. Use this information to answer questions a and b.
a Circle the equation that can be used to find the original price of the t-shirt.
(c - 20c) +.11(e - 200) – 14.21
. 11(x - 20c) = 14.21
11(22.81 - 20(14.21)) = C
116.80c) + (c - 20c) = 14.21
b. Solve the equation and interpret the solution
Answer:
(a) 14.21 = 0.80x + 0.11 (0.80x)
(b) The original price of the t-shirt was $16.
Step-by-step explanation:
The information provided are:
Marvin bought a t shirt that was on sale for 20% off.He paid $14.21. for the t-shirt.The sales tax percent was 11%.(a)
Assume that the original price of the t-shirt was $x.
The discounted amount would be, x ( 1 - 0.20) = 0.80x.
The sales tax amount would be, 0.11 (0.80x).
Then the total amount paid by Marvin can be represented by the equation:
Total = Discounted amount + Sales tax amount
14.21 = 0.80x + 0.11 (0.80x)
Thus, the equation that can be used to find the original price of the t-shirt is:
14.21 = 0.80x + 0.11 (0.80x)
(b)
Compute the value of x as follows:
[tex]14.21 = 0.80x + 0.11 (0.80x)[/tex]
[tex]14.21=0.80\times 1.11\times x[/tex]
[tex]x=\frac{14.21}{0.80\times 1.11}\\\\x=16.0023\\\\x\approx \$16[/tex]
Thus, the original price of the t-shirt was $16.

What is the image of the point (0,5) after a rotation of 180° counterclockwise about
the origin?
Answer:
(0, -5)
Step-by-step explanation:
When we rotate a point around the origin 180°, the original coordinates (x, y) become (-x, -y).
So,
-0 is just 0 (since 0 is both negative and positive)
-(5) is -5
This makes our new point (0, -5).

complete the steps used to solve a system of linear equations by substituting the value of y into one of the original equation s to find the value of x. what is the solution to the system
Answer:
x = 3.5
Step-by-step explanation:
We are given;
1. 3(4x - 7y = 28) -> 12x - 21y = 84
-2(6x - 5y = 31) -> -12x + 10y = 62
2. 12x - 21y = 84
-12x + 10y = -62
-----------------------
-11y = 22
3. y= -2
Since y = - 2, let's put -2 for y into the equation; 12x - 21y = 84
This gives;
12x - 21(-2) = 84
This gives;
12x + 42 = 84
12x = 84 - 42
12x = 42
x = 42/12

What is psychology?Psychology is the scientific study of the mind and behavior, according to the American Psychological Association.
The only way to minimize this effect would be through randomization of students in morning and afternoon classes.
Doing so apply the factor of skill from an individual student to either time of day class greatly lessens the overall effect that it has on the results.
This therefore, minimizes the effect it has on the experiment itself, since the same students that have been studying in a certain time of day would be randomized and not have the same environment that they are used to.

A rectangle has a length of 20 inches. if its perimeter is 64 inches, what is the area?
Answer:
[tex] \boxed{ \bold{ \huge{ \boxed{ \sf 240 \: {inches}^{2} }}}}[/tex]
Step-by-step explanation:
Given,
Length of a rectangle = 20 inches
Perimeter of a rectangle = 64 inches
Area of a rectangle = ?
Let width of a rectangle be ' w ' .
First, finding the width of a rectangle
[tex] \boxed{ \sf{perimeter = 2(l + w)}}[/tex]
plug the values
⇒[tex] \sf{64 = 2(20 + w)}[/tex]
Distribute 2 through the parentheses
⇒[tex] \sf{64 = 40 + 2w}[/tex]
Swap the sides of the equation
⇒[tex] \sf{40 + 2w = 64}[/tex]
Move 2w to right hand side and change it's sign
⇒[tex] \sf{2w = 64 - 40}[/tex]
Subtract 40 from 64
⇒[tex] \sf{2w = 24}[/tex]
Divide both sides of the equation by 2
⇒[tex] \sf{ \frac{2w}{2} = \frac{24}{2} }[/tex]
Calculate
⇒[tex] \sf{w = 12 \: inches}[/tex]
Width of a rectangle ( w ) = 12 inches
Now, finding the area of a rectangle having length of 20 inches and width of 12 inches
[tex] \boxed{ \sf{area \: of \: rectangle = length \: \times \: \: width}}[/tex]
plug the values
⇒[tex] \sf{area \: of \: rectangle =20 \times 12 }[/tex]
Multiply the numbers : 20 and 12
⇒[tex] \sf{area \: of \: rectangle = 240 \: {inches}^{2} }[/tex]
Hence, Area of a rectangle = 240 inches²

Answer:
It will take approximately 9.3 weeks for Kevin to lose the
Step-by-step explanation:
current weight of Dog = 78 pounds
Required weight to be shed off = 14 pounds
weight lost in 1 week = 1.5 pounds
Let the number of weeks required to lose 14 pounds be w.
Assuming that the rate of weight loss per week is constant
(weight lost in 1 week) × (number of weeks) = 14 pounds
1.5 × w = 14
w = 14 ÷ 1.5 = 9.3 weeks
Therefore it will take approximately 9.3 weeks for Kevin to lose the weight
