One more than a number is at least seven. x + 1 > 7
The maximum value of a number is 29. x < 29
The difference of a number and ten is at least 91. x - 10 > 91

Answers

Answer 1

Answer:

Answer:

$3 < x$

$x + 1 \geq 7$

$x \leq 29$

$x - 10 \geq 91$

Step-by-step explanation:

Let the unknown number be x

Three is less than a number: for less than we use < symbol

3 < a number becomes $3 < x$

One more than a number is at least seven: Number atleast 7 means 7 or more than 7. So we use ≥ 7. One more than a number is x+1

$x + 1 \geq 7$

The maximum value of a number is 29: maximum value of x is 29 , so 29 or less than 29. Use ≤ symbol

$x \leq 29$

The difference of a number and ten is at least 91: The difference of a number and 10 is x-10. For at least we use ≥ because 91 is included.

$x - 10 \geq 91$

Answer 2

Answer: Three is less than a number.
3 < x

One more than a number is at least seven.
x + 1 ≥ 7

The maximum value of a number is 29.
x ≤ 29

The difference of a number and ten is at least 91.
x - 10 ≥ 91

Find value of x and y

4.)2x-3y=-15
x=4y

Answers

$\left\{\begin{array}{ccc}2x-3y=-15\nx=4y\end{array}\right\n\nsubstitute\n\n2\cdot4y-3y=-15\n8y-3y=-15\n5y=-15\ \ \ \ \ |both\ sides\ :5\ny=-3\n\nx=4\cdot(-3)=-12\n\nSolution:x=-12\ and\ y=-3.$

2x - 3y = -15
x = 4y
substitute x frm eq2 to eq1
2 (4y) - 3y = -15
8y - 3y = -15
5y = - 15
y = -3
substitute y in eq2
x = 4(-3)
x = -12
y = -3 , x = -12

Dawn and Pablo are members of a normally distributed population that is being sampled. If the chance of Dawn being included in the sample is 0.05%, what must the chance of Pablo being included in the sample be in order to be able to make inferences about the population based on the sample?A) 0%
B) greater than 0% and less than 0.05%
C) 0.05%
D) greater than 0.05%

Answers

Answer: option C) 0.05%

In a normal distribution there are no biases, the chances (probabilities) of any member to be selected are the same. So, the chance to choose Pablo are the same that the chance to choose Dawn.

Answer:

C. 0.05%
