Mathematics
1 answer:
Radda [10]4 years ago
7 0

Answer:

slope = \frac{1}{2}

Step-by-step explanation:

Calculate the slope m using the slope formula

m = \frac{y_{2}-y_{1}  }{x_{2}-x_{1}  }

with (x₁, y₁ ) = (- 1, 1) and (x₂, y₂ ) = (1, 2) ← 2 ordered pairs from table

m = \frac{2-1}{1+1} = \frac{1}{2}

A randomized study compared the effectiveness of two mosquito repellents. The treatment group using Spray A reported a mean of 3
BlackZzzverrR [31]

Answer:

The difference of the means is not significant because the re-randomizations show that it is within the range of what could happen by chance.​

Step-by-step explanation:

Given that:

The treatment group using Spray A reported a mean of 3.5 mosquito bites.

The treatment group using Spray B reported a mean of 5.6 mosquito bites.

After the data are  re-randomized; the differences of the means are shown in the dot plot. The dot plot is attached in the file below;

The best conclusion that can be make based on the data from the dot plot is :

The difference of the means is not significant because the re-randomizations show that it is within the range of what could happen by chance.​

Question 10(Multiple Choice Worth 1 points)
Radda [10]

Answer:

x = 15 and x = -9

(None of the answer choices fits. See explanation below)

Step-by-step explanation:

In mathematics, the modulus of a number, denoted by enclosing the number within vertical bars is the absolute value of the number. If the number is negative the sign is disregarded and the number is treated as positive

For example, | -10 | = 10 and | 10 |  is also 10

Solve for | x- 3 | in the equation

\frac{1}{2} | x-3 | + 4 = 10

Subtracting 4 on both sides yields  \frac{1}{2} | x-3 | + 4 -4 = 10 - 4

Simplifying \frac{1}{2} | x-3 | = 6

Multiplying by 2 on both sides yields | x-3 | = 12

We do not know if |x-3| is negative or positive since |-12| = |12| =12

So we have 2 possibilities

If x - 3  is negative, then x - 3 = -12 ==> x = -9

If x -3 is positive, then x-3 = 12  ==>  x = 15

So the possible values are x = -9 and x = 15

None of the answer choices fits these values indicating either an error in the answer choices or the original equation
