The probability of getting a green of a yellow marble can be determined like this:

Probability = (yellow marbles + green marbles) / total number of marbles

Probability = (1 + 4) / 10

Probability = 5 / 10

Probability = 1/2

By multiplying the given probability by the number of times a marble will be drawn, we get how many times we can predict that a green or a yellow marble will be picked, then we get:

Number of predictions = 150 × 1/2

Number of predictions = 75

Then, the answer is 75 times

Answer:

75 times.

Step-by-step explanation:

There are a total of 10 marbles in the bag.

Probability a green marble is drawn (in 1 draw) = 4/10 = 2/5.

In 150 draws you can expect to draw 150* 2/5 = 60 green marbles.

Probability a yellow marble is drawn (in 1 draw) = 1/10.

In 150 draws you can expect to draw 150* 1/10 = 15 yellow marbles.

So, the number of times for a green or yellow marble

= 60+15= 75.

Answer:

A

Step-by-step explanation:

It is given that lines k and p are parallel. You also know that angles 2 and 3 are equal because of vertical angles. Due to the parallel lines, you can say that angles 1 and 2 are equal because they are corresponding angles (same-side).

These two angles are not alternate interior angles because angle 1 is exterior and on the same side as angle 2. The third option would not make sense because you are trying to prove two angles are equal, not that lines are parallel.

Answer: A.

If the remaining balance for 48 months with an APR of 4.5%. the monthly payment that Jenna pays is: $595.17.

Using this formula to determine the monthly payment

P = A ×r × ( 1 +r)^n  ÷( 1+ r)^n -1

Where:

P = Principal = ?

A = Amount = $29,000 × ( 1- .10) = 26,100

r = Interest rate = 4.5% / 12 = 0.00375

n = number of months = 48 months

Let plug in the formula

P = 26,100 × 0.00375 × ( 1+ 0.00375)^ 48 ÷ ( 1+ 0.00375)^ 48 -1

P = 26,100 × 0.00375 × ( 1.00375)^ 48 ÷ ( 1.00375)^ 48 -1

P = 26,100 × 0.00375 × 1.196814377  ÷  1.196814377 -1

P = 26,100 × 0.00375 × 1.196814377  ÷  0.196814377

P = $117.1382456  ÷  0.196814377

P = $595.17

The researcher draws a random sample using a Multistage cluster sample

At each stage, you use smaller and smaller groups (units) to select a sample from a population. National surveys are frequently used to collect data from a large, geographically dispersed group of people. To use as your sample, you randomly select individual units from the cluster.

In multistage cluster sampling, the population is divided into clusters and some clusters are chosen in the first stage. You continue to break up the selected clusters into smaller clusters at each subsequent stage, and you do this until you reach the final step. In the final step, only a few members of each cluster are chosen for your sample.

Vector a = (3, 2), then;

Also, vector b = (-5, 6), then;

Then, -3a + 2b = (-9, -6) + (-10, 12)

The answer is (-19,6)

Answer:

x = 3 and y = 5

Step-by-step explanation:

1st: The sum of the same side interior angles equal 180°. Use this to solve for x.

45x - 5 + 16x + 2 = 180

61x - 3 = 180

61x - 3 + 3 = 180 + 3

61x/61 = 183/61

x = 3

2nd: find the measure of angle 16x + 2

16x + 2

16(3) + 2

48 + 2

50°

3rd: the sum of the 50° angle and the angle 26y° is 180 since they make a straight angle. Make an equation and solve for y.

50 + 26y = 180

50 - 50 + 26y = 180 - 50

26y = 130

26y/26 =130/26

y = 5

The two linear equations are perpendicular.

Here we have the two linear equations:

12y - 4x = 84

y = -3x + 8

If we write both of them in the slope-intercept form (as the second one) we will get:

12y - 4x = 84

12y = 4x + 84

y = (4x + 84)/12

y = (1/3)*x + 7

Now, if we take the product of the slopes of the two lines, we get:

p = -3*(1/3) = -1

when this product is -1, the lines are perpendicular, so that is the relation between our lines.

b) Between 210 and 220 for the average of 25 eggs: 0.8164 = 81.64%.

c) Third quartile for the average of 25 eggs: 213 milligrams.

d) Less than 220 if less than 210: 0.1011 = 10.11%.

The z-score of a measure X of a normally distributed variable that has mean represented by [tex]\mu[/tex] and standard deviation represented by [tex]\sigma[/tex] is given by the rule presented as follows:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The mean and the standard deviation for the cholesterol levels are given as follows:

[tex]\mu = 215, \sigma = 15[/tex]

For item a, the probability is the p-value of Z when X = 220 subtracted by the p-value of Z when X = 210, hence:

X = 220:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

Z = (220 - 215)/15

Z = 0.33

Z = 0.33 has a p-value of 0.6293.

X = 210:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

Z = (210- 215)/15

Z = -0.33

Z = -0.33 has a p-value of 0.3707.

Hence the probability is:

0.6293 - 0.3707 = 0.2586.

For item b, we are dealing with a sample of 25, hence we apply the Central Limit Theorem as follows:

n = 25, s = 15/sqrt(25) = 3.

X = 220:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

By the Central Limit Theorem

[tex]Z = \frac{X - \mu}{s}[/tex]

Z = (220 - 215)/3

Z = 1.33

Z = 1.33 has a p-value of 0.9082.

X = 210:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

Z = (210 - 215)/15

Z = -1.33

Z = -1.33 has a p-value of 0.0918.

Then the probability is:

0.9082 - 0.0918 = 0.8164 = 81.64%.

The third quartile is X when Z has a p-value of 0.25, so X when Z = -0.675, hence:

[tex]Z = \frac{X - \mu}{s}[/tex]

-0.675 = (X - 215)/3

X - 215 = -0.675 x 3

X = 213.

The conditional probability in item d is calculated as follows:

P(X < 210)/P(X < 220) = 0.0918/0.9082 = 0.1011 = 10.11%.

The rate of the slowest car is 86 km/hr using the concept of relative velocity.

Relative speed is the rate at which one moving body moves in relation to another. The differential between two moving bodies determines their relative speed while they are traveling in the same direction. However, when two bodies are traveling in opposition to one another, the relative speed is determined by averaging their respective speed.

Let the speed of 1st car is v₁.

Let the speed of 2nd car is v₂.

v₁- v₂ = 18 km/hr --- (1)

And using the concept of relativity.

S(rel) = D(rel)/time

S(rel) = 360 / 2

S(rel) = 190

v₁ + v₂ = 190 --- (2)

Adding equations 1 and 2 we get

v₁ = 104 km/hr

The rate of change of angle of elevation between the radar station and airplane is

                       [tex]\displaystyle \frac{-10}{109} \left(\frac{rad}{min}\right)[/tex]

The airplane is flying at the speed of 200 mph

The airplane is at an altitude of 3 miles over the radar station

The distance travelled by the airplane after 3 mins

      distance = speed x time

                     = 200 mi/hr x 3 min

Since the speed is hour let us convert it to mins

                     = 200 x 3 x 1/60

                     = 600 / 60

                    = 10 miles

So , let us assume that the airplane is exactly at the top of the radar station at an altitude of 3 miles

Then the elevation angle of the between radar station and airplane can be find by

                              tan θ = O / A
where O is the opposite side to the angle of elevation

          A is the adjacent side to the angle of elevation.

But we need the find the rate of change of angle of elevation , so let us differentiate on both side with respect to time

                                [tex]\displaystyle sec^{2}\theta\frac{ d\theta }{dt} = \frac{A \frac{dO}{dt} - O \frac{dA}{dt} }{A^{2}}[/tex]

                                        [tex]\displaystyle \frac{ d\theta }{dt} = \frac{A \frac{dO}{dt} - O \frac{dA}{dt} }{sec^{2}\theta A^{2}}[/tex]

                                       [tex]\displaystyle \frac{d\theta}{dt} = \frac{10 (0) - 3 (200 mi/hr)}{sec^{2}(10)^{2}}[/tex]

The altitude is gonna be a constant , thus the derivative of altitude will be zero whereas , the the distance travelled by airplane is changing with respect to time.

                                   [tex]\displaystyle \frac{d\theta}{dt} = \frac{10 (0) - 3 (200 mi/hr)}{\frac{109}{100}(10)^{2}}[/tex]

We had found the value of sec²θ = (hyp/adj)²

                                    [tex]\displaystyle \frac{d\theta}{dt} = \frac{-600}{109} \frac{rad}{hr}[/tex]

Now , let us convert in terms of rad/min

                                   [tex]\displaystyle \frac{d\theta}{dt} = \frac{-600}{109} \left(\frac{1}{60}\right)[/tex]

                                  [tex]\displaystyle \frac{d\theta}{dt} = \frac{-10}{109} \left(\frac{rad}{min}\right)[/tex]    

Therefore , the rate of change of angle of elevation is -10/109 (rad/min)
