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
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).

Answer:
[tex] \frac{6}{8} \div \frac{2}{3} [/tex]
Simplify,
[tex] \frac{6}{8} = \frac{3}{4} [/tex]
So now,
[tex] \frac{3}{4} \div \frac{2}{3} \\ = \frac{3}{4} \times \frac{3}{2} \\ = \frac{3 \times 3}{4 \times 2} \\ = \frac{9}{8} \\ = 1.125[/tex]

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.

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.

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

Answer:
Step-by-step explanation:
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.

Answer: 48 sq km
Step-by-step explanation:
The length of the rectangular prism is 8 kilometers. The width is 3 kilometers. Lastly, the height is 2 kilometers. The formula for a rectangular prism is lwh, or length x width x height. 8 x 3 x 2 = 48 sq km.
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

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.
Can someone please help me?
Answer:
Question 1: The answer is "He could ask each person in his class who is the tallest person in the class."
Question 2: The mode is 56.
Step-by-step explanation:
Explanation 1: A statistical question is a question that can be answered by collecting data that varies. For example, “How old am I?" is not a statistical question, but “How old are the students in my school?” is a statistical question. Therefore, when we look at the options, the second option is the best.
Explanation 2: To find the mode we have to find which number is most frequent through out the set. When we look at the numbers, there are 3 numbers that have 56. Therefore, 56 is the mode.
Point P lies on circle C, x^2+y^2=36. There are two unique tangents to circle D, x^2+y^2=18 that pass through point p. What is the measure of the angle between the two tangent lines?
Answer:
90°Step-by-step explanation:
Refer to attached
Red circle is C with radius 6 and green circle is D with radius √18.
PM and PN are tangents to circle D.
M and N are right angles as tangents are perpendicular to radius.
We need to find the measure of ∠MPN.
We'll work out this angle using trigonometry:
OM / OP = sin (∠MPO) sin (∠MPO) = √18/6 = √2/2m∠MPO = arcsin ( √2/2) = 45°∠NPO is same as ∠MPO, therefore:
m∠MPN = 45°*2 = 90°
