Can someone please help me?

Answer:

1.

The explanatory variable is the level of education.

response variable is Rate of motor vehicle crash deaths

2. b

3. A) Without an experiment, no causal relationship can be made.

Step-by-step explanation:

1.

The explanatory variable is the level of education.

The explanatory variable tells us that more education among people over 25 years, brings about a reduction in motor deaths.

The response variable is the rate of motor vehicle deaths.

This variable actually responds to the changes in the explanatory variable. The rate of motor vehicle deaths could increase or decrease based on the level of education.

2.

They are lurking variables. option B

These variables are not known primarily as explanatory variables here in this relationship but they have the ability to affect the result of the study.

3. We have to carry out an experiment first in order to carry out a causal relationship.

Answer:

99.

Step-by-step explanation:

A palindrome number is one that can be read in the same way both from the front and from the back. A clear example is the number 242, which starts and ends in the same way from the front or back.

Between 10 and 100, there are 9 palindromes, from 11 to 99. In turn, between 100 and 200, 200 and 300 and so on, each hundred has within it 10 palindromes (101, 111, 121, 131, 141 , 151, 161, 171, 181 and 191, for example).

Therefore, considering the 9 hundreds between 100 and 1000, there will be 90 palindromes, which added to the 9 between 10 and 100 give a total of 99 palindromes.

Answer:

[tex]\frac{11}{36} = 0.3056[/tex] probability that at least one dies shows a 5.

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

Each dice:

6 sides, one of which is 5.

So 6-1/6 = 5/6 probability of rolling a 5.

Probability of not rolling a five in two rolls:

(5/6)^2 = 25/36

Probability of rolling a five in at least one of the rolls:

[tex]p = 1 - \frac{25}{36} = \frac{36}{36} - \frac{25}{36} = \frac{11}{36} = 0.3056[/tex]

[tex]\frac{11}{36} = 0.3056[/tex] probability that at least one dies shows a 5.

Answer:

3/5

Step-by-step explanation:

In the numbers 1 thru 10, there are 5 multiples of 2 (2, 4, 6, 8, 10) and 2 multiples of 5  (5, 10).  Since you cannot count 10 twice, there are 6 possibilities (2, 4, 5, 6, 8, 10)

So the probability of spinning a multiple of 2 or 5 is 6/10 = 3/5

Answer:2/10 probabilty for the multiple of 5 and a 5/10 or 50% chance that it will be a multiple of 2

Step-by-step explanation: 10 areas, there are 2 multiples of 5,( 5 and 10 )and there is a 2/10 chance of landing on landing 5 or 10 because there are 2 multiples of 5. There are also 5 multiples of 2, (2, 4, 6, 8, 10) 5/10 chance because there are 5 multiples out of 2

Answer:

y = -4/9x + 1/3 letter H

Step-by-step explanation:

Let's solve for y. 4x+9y=3 Step 1: Add -4x to both sides. 4x+9y+−4x=3+−4x 9y=−4x+3 Step 2: Divide both sides by 9. 9y 9 = −4x+3 9 y= −4 9 x+ 1 3

Let's assume the number as x

According to the question,

2/3x-6=22

2x-6=22×3

2x= 66-6

2x=60

x=60/2=30

Therefore, as x=30, The number is 30 itself.

Answer:

Divide a percent by 100 and remove the percent sign to change it  from a percent to a decimal.

Step-by-step explanation:

1. Example: 9 % is 0.09

2. Example: 8% is 0.08

3 .Example: 10% will change to 10/100 =decimal 0.10

That how it work just follow the example

Answer:

The Area of a Segment is the area of a sector minus the triangular piece (shown in light blue here). There is a lengthy reason, but the result is a slight modification of the Sector formula: Area of Segment = θ − sin(θ) 2 × r2 (when θ is in radians) Area of Segment = ( θ × π 360 − sin(θ)2 ) × r2 (when θ is in degrees)

For the solution [tex](3,\frac{1}{3})[/tex] of the given system of equations, the value of x - y is [tex]2\frac{2}{3}[/tex]

To determine the value of x - y, we will solve the two equations simultaneously

We have

7x + 3y = 8 ------ (1)

6x – 3y = 5 ----- (2)

Solving by the elimination method

Add equations (1) and (2) together

We get

[tex]7x + 6x +3y -3y = 8 + 5[/tex]

Then,

[tex]13x = 13[/tex]

Now, divide both sides by 13

[tex]\frac{13x}{13} = \frac{13}{13}[/tex]

∴ [tex]x = 1[/tex]

Now, substitute the value of x into equation (1)

[tex]7x + 3y = 8[/tex]

We get

[tex]7(1) + 3y = 8[/tex]

[tex]7 + 3y = 8[/tex]

[tex]3y = 8-7[/tex]

Then,

[tex]3y = 1[/tex]

Divide both sides by 3

[tex]\frac{3y}{3} =\frac{1}{3}[/tex]

∴ [tex]y = \frac{1}{3}[/tex]

The solution to the system of equations is [tex](3,\frac{1}{3})[/tex]

Now, for the value of x - y, we will input the values of x and y

That is,

[tex]x -y = 3 -\frac{1}{3}[/tex]

[tex]= 2\frac{2}{3}[/tex]

∴ [tex]x-y =2\frac{2}{3}[/tex]

Hence, the value of x - y is [tex]2\frac{2}{3}[/tex]
