Answer:

40 degrees

Step-by-step explanation:

We need to find angle 3

Since angle 2 and angle 4 are vertical angles, they will be congruent

To solve for x we can make the following equation:

x+70=2x

x=70

In this problem angles 2 and 3 are supplementary (they add to 180)

Angle 2 is 140 degrees

We can now make the following equation to find angle 3 using measures addition postulate

let angle 3 be x

180-140=x

The 140 is angle 2

x=40

Suppose A gas station monitors how many bags of ice they sell along with the maximum daily temperature for 100 days. A gas station data analysis plots the data in a scatterplot with temperature, in degrees Fahrenheit, on the horizontal axis and the number of bags of ice sword on the vertical axis. She calculates a linear correlation coefficient of r= 0.9972. The mean Temperature is 83.8959 degrees Fahrenheit with a standard deviation of 11.2921 Degrees Fahrenheit. The mean number of ice bags sold is 70.3873 with a standard deviation of 27.8 913.

Answers

Answer:

hello your question is incomplete attached below is the complete question

answer :

a ≈ - 136

b = 2.46

Step-by-step explanation:

A) we apply the formula for slope in regression

b = r * [tex]\frac{Sy}{Sx}[/tex]   --------- ( 1 )

where:

standard deviation (Sy)  = 27.8913

standard deviation ( Sx ) = 11.2921

Linear correlation coefficient ( r ) = 0.9972

substitute given values into equation 1

b = 2.46

for intercept A

a = Y - b * X  --------- ( 2 )

Mean number of ice bags sold ( Y )= 70.2873

b = 2.46

Mean temperature ( X )= 83.8959

substitute given values into equation 2

a = 70.2873 - ( 2.46 * 83.8959 )

  = - 135.997

Benjamin decided to himself to breakfast at Seva restaurant he ordered chocolate milk that cost $3.25 then he wants the bio as many pan cakes as he can but he wants to be able to be at most $30 before tax the restaurant only sells pancakes in stacks oh for pancakes cakes for $5.50. Let S represent the number of stacks of pancakes that Benjamin buys which any inequality describe this scenario

Answers

Answer: 3.25 + 5.50s ≤ 30

Step-by-step explanation:

The following information can be gotten from the question.

Cost of chocolate milk = $3.25

Cost of stack pancake = $5.50

Maximum amount to be spent by Benjamin = $30

Number of stacks of pancakes to be bought = s

First, we need to calculate the stacks of pancakes that Benjamin can buy. This will be:

= $5.50 × s

= 5.50s

Therefore, the total money that Benjamin will spend will be:

= 3.25 + 5.50s

Since he wants to be able to be at most $30 before tax, the inequality can be written as:

= 3.25 + 5.50s ≤ 30

What is transformation?

A transformation is a general term for four specific ways to manipulate the shape and/or position of a point, a line, or geometric figure.

Given are two triangles ABC and XYZ.

We have AB = XY = 25 cm, AC = YZ = 29 cm

and also angle A = angle X = 36 degrees

Thus, we find that corresponding congruent sides are

AB and AC with angles A and X

To map ABC onto XYZ,

Vertex B to Y, side AB to side XY with AC coinciding with XZ

Now all vertices x, y, z will perfectly match with transformed ABC

Hence, The correct answer is vertex B to vertex Y

The equation y = 1.2x represents the rate, in beats per second, that Lee's heart beats. The graph represents the rate that Nancy's hear beats. Determine whose heart is beating at a faster rate.

Answers

Answer:

Nancy's heart rate is higher than Lee's heart rate.

Step-by-step explanation:

Equation for the heart beats of Lee is,

y = 1.2x

And the heart beats of Nancy is represented by the graph.

Higher the slope of the line = Faster the hear rate.

Slope of line represented by y = 1.2x,

m = 1.2

Similarly, slope of the line given in the graph = [tex]\frac{\text{Rise}}{\text{Run}}[/tex]

                                                                           = [tex]\frac{5}{4}[/tex]

                                                                           = 1.25

Since, slope of the line representing Nancy's heart rate is greater than slope of the line representing Lee's heart rate.

Therefore, Nancy's heart rate is faster than Lee's heart rate.

Find the range of the function f(x) = 3x - 2, given the domain {-4, 0, 4}

Answers

Answer:

{-14, -2, 10}

Step-by-step explanation:

To find the range, you can use all the domain values and find the output.

f(-4) = 3(-4) - 2

f(-4) = -12 - 2

f(-4) = -14

f(0) = 3(0) - 2

f(0) = 0 - 2

f(0) = -2

f(4) = 3(4) - 2

f(4) = 12 - 2

f(4) = 10
