Answer:

-4

Step-by-step explanation:

Find the gradient of the line segment between the points (0,2) and (-2,10).

Given data

x1= 0

x2= -2

y1= 2

y2=10

The expression for the gradient is given as

M= y2-y1/x2-x1

substitute

M= 10-2/-2-0

M= 8/-2

m= -4

Hence the gradient is -4

Helene claimed that the expected value when rolling a fair die was 3.5. Steve said that wasn't possible. He said that the expect

Nesterboy [21]

Answer:

Helene is right

Step-by-step explanation:

Mathematically, the expected values is defined as the sum of all the possible outcomes that an event can have times the probality of the respective outcome:

x = ∑ p *i,

where x is the expected value, i represents every outcome that can occur, and p is the probability of said outcome.

Now, for the case of a dice, the expected value would be:

x = 1 * $\frac{1}{6}$ + 2 * $\frac{1}{6}$ + 3 * $\frac{1}{6}$ + 4 * $\frac{1}{6}$ + 5* $\frac{1}{6}$ + 6 * $\frac{1}{6}$ ,

as every outcome has the same chance of happenning. Solving we get that:

x= $\frac{1}{6}$ *(1 +2 +3 +4+5+6) = $\frac{1}{6}$ * 21 = 3.5

Helene is right.

Substitutions <br> y=x+4<br> y=3x+0

cluponka [151]

Answer:

x = 2

Step-by-step explanation:

since both equal y, you can set them equal to each other

x + 4 = 3x + 0

subtract x on both sides

4 = 2x

divide by 2 on both sides

2 = x

Using the box plots given:

1. Median for 6th graders = 2.5; 4th graders = 1.5

2. Difference of spread = 1

3. Variability for 6th graders = 1.9; 4th graders = 1

4. TRUE, TRUE, FALSE, TRUE

5. C.

<h3>What is the Five-number Summary Displayed by a Box Plot?</h3>

In a typical box plot as shown in the image attached below, the five-number summary that a box plot displays include min and max values, lower and upper quartiles, and the median.

The spread = the range = max value - min value

The variability = IQR = Q3 - Q1.

1. Median for 6th graders = 2.5

Median for 4th graders = 1.5

2. Spread for 6th graders = 4 - 0 = 4

Spread for 4th graders = 3 - 0 = 3

Difference of spread = 4 - 3 = 1

3. Variability for 6th graders (IQR) = 3.4 - 1.5 = 1.9

Variability for 4th graders (IQR) = 2 -1 = 1

4. TRUE, Q3 for 4th graders < Q3 for 4th graders

TRUE, Q1 for 6th graders = median for 4th graders

FALSE, rather the max for 6th graders > max for 4th graders

TRUE, both grades have at least 1 students who do not participate.

5. C. Max for April = median for March.
