Answer:
Most people found the probability of just stopping at the first light and the probability of just stopping at the second light and added them together. I'm just going to show another valid way to solve this problem. You can solve these kinds of problems whichever way you prefer.
There are three possibilities we need to consider:
Being stopped at both lights
Being stopped at neither light
Being stopped at exactly one light
The sum of the probabilities of all of the events has to be 1 because there is a 100% chance that one of these possibilities has to occur, so the probability of being stopped at exactly one light is 1 minus the probability of being stopped at both lights minus the probability of being stopped at neither.
Because the lights are independent, the probability of being stopped at both lights is just the probability of being stopped at the first light times the probability of being stopped at the second light. (0.4)(0.7) = 0.28
The probability of being stopped at neither is the probability of not being stopped at the first light, which is 1-0.4 or 0.6, times the probability of not being stopped at the second light, which is 1-0.7 or 0.3. (0.6)(0.3) = 0.18

Step-by-step explanation:
There are five blue jelly beans, two red jellybeans, one orange jellybean and 2 pink jellybeans in a bag. Once a Jellybean is drawn, it’s not replaced. Find the probability of selecting a blue jellybean and then a pink jellybean.
A) 1/10
B) 1/9
C) 1/100
D) 1/125
Thank you! Have a great day! :D
Answer:
1/9
Step-by-step explanation:
Probability = Expected outcome/Total outcome
Since we have five blue jelly beans, two red jellybeans, one orange jellybean and 2 pink jellybeans in a bag
Total outcome = 5 + 2 + 1 + 2
Total outcome = 10
Probability of selecting a blue = 5/10 = 1/2
Since it is not replaced, the total ball remaining will be 9
If pink jellybean is picked after, the probability of picking a pink will be 2/9
Hence probability of selecting a blue jellybean and then a pink jellybean = 1/2 * 2/9 = 1/9

What is the approximate length of the missing side of a
right triangle with hypotenuse of 16 cm and other side of
15 cm?
Answer:
The approximate length of the missing side is of 5.57 cm.
Step-by-step explanation:
Pythagorean Theorem:
In a right triangle with sides a and b and hypotenuse c, the Pythagorean theorem states that:
[tex]a^2 + b^2 = c^2[/tex]
In this question:
[tex]a = 15, c = 16[/tex]
We want to find b. Then
[tex]a^2 + b^2 = c^2[/tex]
[tex]15^2 + b^2 = 16^2[/tex]
[tex]b^2 = 256 - 225[/tex]
[tex]b^2 = 31[/tex]
[tex]b = \sqrt{31}[/tex]
[tex]b = 5.57[/tex]
The approximate length of the missing side is of 5.57 cm.
please help on number 2 the table represents a linear relation use the table to identify the y-intercept please help i have an f and a couple zeros plz will give brainly
Answer:
y = 7x + 4
Step-by-step explanation:
From the table given in the picture attached,
Let the linear equation representing the table is,
y = mx + b
Here, m = Slope of the equation
b = Y-intercept
Since, slope of the line passing through [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is given by,
m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
Therefore, slope of the line passing through (20, 144) and (24, 172) will be,
m = [tex]\frac{172-144}{24-20}[/tex]
m = [tex]\frac{28}{4}[/tex]
m = 7
By substituting the value of m in the equation,
y = 7x + b
Since, this line passes through a point (20, 144),
By substituting the values of x = 20 and y = 144 in the equation,
144 = 7(20) + b
b = 144 - 140
b = 4
Therefore, equation of the line will be,
y = 7x + 4
Find the equation of this line.

Answer:
y = 3/4x + 2
Step-by-step explanation:
If we take the given points to be (0, 2) and (4, 5), then the slope is ...
m = (y2 -y1)/(x2 -x1) = (5 -2)/(4 -0) = 3/4
The y-intercept is given by the point (0, 2). So, the equation is ...
y = mx + b . . . . . . line of slope m with y-intercept b
y = 3/4x + 2

Maria and her friends eat pizza for lunch.
There are 6 pizzas with 10 slices each. If
Maria and her 15 friends eat 3 slices each,
how many slices are left over?
Answer:
15 slices
Step-by-step explanation:
The total number of slices is equal to 60 (6x10=60) and if each friend eats 3 slices, they will all collectively eat 45 slices (15x3). If they eat 45 out 60 slices they will have 15 slices left over (60-45=15).

Use the value of the linear correlation coefficient r to find the percentage of the total variation that can be explained by the linear relationship between the two variables. r = 0.234 (Your answer should be a percent rounded to two decimal places as needed.)
Answer:
5.47% of the total variation between the two variables can be explained by the regression line.
Step-by-step explanation:
Given :
R value = 0.234
The R value is the correlation Coefficient ; which gives the type and level of correlation between two variables.
However, to Obtian the percentage variation which can be explained by by the regression line, we have to obtain the Coefficient of determination, R².
R² value is Obtained by taking the squared of the correlation Coefficient
Hence,
R² = 0.234² = 0.054756
R² = 0.05476 * 100% = 5.4756%
Hence, R² = 5.48%
This is interpreted as ; 5.47% of the total variation between the two variables can be explained by the regression line.
Example 5:
Mrs. Williams writes the following number on the board.
276,954
She instructs her students to write a number where the value of the 6 in their number is 10
times greater than the value of the 6 in the number on the board. Duwan writes the number
286,123. Is his answer correct? Explain how you know.
Answer:
No Duwan is in incorrect.
Step-by-step explanation:
When it asks for a number to be 10x greater, the answer would be in a digit that is 1 greater. For example 10x greater than 10 would be 100. You move the digit up once. An answer that Duwan could have used is: 260,000.

You want to visit your friend, John, at his house. You leave your house and walk down Oak Street which is at an angle 45◦ from Elm Street which is the street in front of your house. After walking 6 blocks, you arrive at John’s house. How far is Oak Street from Elm Street? Round to the nearest tenth of a block.
Use SOH CAH TOA to find d.
Answer:
4.2 blocks
Step-by-step explanation:
Reference angle (θ) = 45°
Opposite side to θ = d
Hypotenuse = 6
Using SOHCAHTOA, we would apply SOH since the Hypotenuse and Opposite side is what we are concerned with.
Thus:
Sin θ = Opp/Hyp
Substitute
Sin 45° = d/6
Multiply both sides by 6
6 × Sin 45 = d
d = 4.24264069
d = 4.2 (nearest tenth)
Therefore, the distance of Oak Street from Elm Street = 4.2 blocks

Answer and Step-by-step explanation:
To get the x values, we can plug in the y values and solve for x.
1 = 0.5x + 2
Subtract 2 from both sides.
-1 = 0.5x
Divide both sides by 0.5.
-2 = x
2 = 0.5x + 2
Subtract 2 from both sides.
0 = 0.5x
Divide both sides by 0.5.
0 = x
3 = 0.5x + 2
Subtract 2 from both sides.
1 = 0.5x
Divide both sides by 0.5.
2 = x
Those are the answers.
