7. Eduardo has $150 in savings and makes $9.75 per hour. Jennifer has $90 in savings and earns $15.25 for each

Stells [14]

Answer:

a) 150-90 = h(15.25 -9.75)

b) 10.91

Step-by-step explanation:

a) Jennifer has 150 -90 = 60 less in savings than Eduardo, but she is earning 15.25 -9.75 = 5.50 more per hour. An equation she can use to figure her hours is ...

60 = 5.50h . . . . for h hours worked.

In 'raw' form, that might be ...

150 -90 = (15.25 -9.75)h

b) Solving the above equation, we get ...

60/5.50 = h ≈ 10.90909 ≈ 10.91 . . . hours

What is a statistical question and what is its purpose? Be sure to include the 3 characteristics that make it up.

sattari [20]

Answer:

Step-by-step explanation:

What is a statistical question and what is its purpose? Be sure to include the 3 characteristics. That makes it up.

Answer- and statistical question is a question that guides research by defining the population of a given topic and that anticipates variability in the collected data. The purpose of a statistical question is it is the first step of the statistical process. The 3 characteristics of a statistical question are allows for clear responses, includes a specific population, and anticipates variability of the data.

What does it mean for data to have variability as it refers to statistical questions? Give an example.

A statistical question has more than one possible answer

Example- how many chores do you have? Some people might say 5 or 2 or even 0. It just depends on the person's family.

Well a dot diagram is like this for example,

And a histogram is this,

Dot diagram uses dots and the histogram uses bars.

When would we use them? Well that I can explain, you can use the dot diagram to see what pets people have or even to see how many people scored how many points.

A histogram can be used for a concert. There would be like on the bottom, 0-6, 7-12, and so on. The bars show how many people from what age group are joining the concert.

Explain the difference between center and shape of a data set.

The center is the median and/ or mean of the data. The spread is the range of the data. And, the shape describes the type of graph.

hope this helps give brainiest.

15x-7=2+12x I need help with this

Amanda [17]

Answer:

$\huge{ \boxed{ \bold{ \tt{x = 3}}}}$

<h3>♁ Question : Solve for x</h3>

15x - 7 = 2 + 12x

<h3>♁ Step - by - step explanation</h3>

$\text{15x - 7 = 2 + 12x}$

Move 12x to L.H.S ( Left Hand Side ) and change it's sign

➛ $\sf{15x - 12x - 7 = 2}$

Move 7 to R.H.S ( Right Hand Side) and change it's sign

➛ $\sf{15x - 12x = 2 + 7}$

Subtract 12x from 15x

Remember that only coefficients of like terms can be added or subtracted.

➛ $\sf{3x = 2 + 7}$

Add the numbers : 2 and 7

➛ $\sf{3x = 9}$

Divide both sides by 3

➛ $\sf{ \frac{3x}{3} = \frac{9}{3}}$

➛ $\boxed{ \bold{ \sf{x = 3}}}$

The value of x is $\boxed{ \sf{3}}$

✄ ✄ ✄ ✄ ✄ ✄ ✄ ✄ ✄ ✄ ✄ ✄ ✄ ✄ ✄

☄ Now, let's check whether the value of x is 3 or not!

<h3>☥ Verification :</h3>

$\sf{15x - 7 = 2 + 12x}$

$\dashrightarrow{ \sf{15 \times 3 - 7 = 2 + 12 \times 3}}$

$\dashrightarrow{ \sf{45 - 7 = 2 + 36}}$

$\dashrightarrow{ \sf{38 = 38}}$

L.H.S = R.H.S ( Hence , the value of x is 3 ).

✄ ✄ ✄ ✄ ✄ ✄ ✄ ✄ ✄ ✄ ✄ ✄ ✄ ✄ ✄

<h3>✒ Rules for solving an equation :</h3>

If an equation contains fractions ,multiply each term by the L.C.M of denominators.
Remove the brackets , if any.
Collect the terms with the variable to the left hand side and constant terms to the right hand side by changing their sign ' + ' into ' - ' and ' - ' into ' + ' .
Simplify and get the single term on each side.
Divide each side by the coefficient of variable and then get the value of variable.

Hope I helped!

Have a wonderful time ! ツ
