1. Without computing, state whether the
sign is positive or negative in each of the
following cases:
32 * (-12)
; 4.75 × (-2.4) < 3;
(-2.15) * (-14.6); (-2) (-3) × (-7);
10.5*(-2)*(-3.5); (-3.7)*(-2.6)*(-0.7)x4​

Answer:

1. 32 * (-12) = negative

2. 4.75 * (-2.4) < 3 = negative

3. (-2.15) * (-14.6) = positive

4. (-2) (-3) × (-7) = negative

5. 10.5*(-2)*(-3.5) = positive

6. (-3.7)*(-2.6)*(-0.7)x4​ = negative

On a math quiz, you earn 10 points for each question answered correctly. In the equation below, x represents the number of questions that you answer correctly on this quiz, and y represents the total number of points you score on this quiz. The relationship between these two variables is modeled by the equation y = 10x.
What is the independent variable?
A) The value of 10 in the equation.
B) The total number of points scored on the exam.
C) The number of questions answered correctly on the exam.
D) The independent variable cannot be determined from the given information.​

Identify the multiplication problem that matches the model

Maria has two routes, E and W, she can take when commuting to work. Both routes go through a railroad crossing, and sometimes she needs to stop at the crossing to allow trains to pass. She claims that the proportion of times she needs to stop when taking route E is different from the proportion of times she needs to stop when taking route W. She conducted the following hypothesis test at the significance level of α=0.10.

H0: pE=pW
Ha: pE≠pW
In the hypotheses, pE represents the proportion of times she needs to stop at the crossing when using route E, and pW represents the proportion of times she needs to stop at the crossing when using route W.

All conditions for inference were met, and the resulting p-value was 0.37. Which of the following is the correct decision for the test?


The p -value is less than alpha , and the null hypothesis is rejected. There is convincing evidence to support the claim that the proportion of times she needs to stop at the crossing is different for the different routes.

The p -value is greater than alpha , and the null hypothesis is not rejected. There is convincing evidence to support the claim that the proportion of times she needs to stop at the crossing is the same for the different routes.

The p -value is greater than alpha , and the null hypothesis is rejected. There is not convincing evidence to support the claim that the proportion of times she needs to stop at the crossing is different for the different routes.

The p -value is greater than alpha , and the null hypothesis is not rejected. There is not convincing evidence to support the claim that the proportion of times she needs to stop at the crossing is different for the different routes.

The p-value is greater than α, and the null hypothesis is rejected. There is convincing evidence to support the claim that the proportion of times she needs to stop at the crossing is different for the different routes.

A school rewards students for good work by giving them merit points.
James has x merit points.
Sarah has four times as many merit points than James.
Robert has 31 fewer merit points than James.
Each merit point is worth 3 pence.
All three of the students have a total of £14.73
Work out how many merit points each student has.

Using the pattern, create an equation (rule) that describes this pattern.
