Answer:
hmmmm im thinking
Step-by-step explanation:
A business school is conducting a study to investigate whether a students’ scores on a placement test can be used to predict students’ starting salaries. Based on a random sample of 200 graduates of the business school, a 98 percent confidence interval for the slope of the linear regression line relating placement scores and starting salary is calculated to be (315,336). Assume the conditions for inference are met.
Which of the following is a correct interpretation of the confidence interval?
a. There is a 98 percent probability that the slope of the population regression line is between $315 per point and $336 per point.
b. Ninety-eight percent of the time, a 10-point increase in placement score will result in an average increase between $3,150 and $3,360 in starting salary.
c. We are 98 percent confident that a 10-point increase in placement score will result in a predicted increase in starting salary of between $3,150 and $3,360.
d. We are 98 percent confident that predicted starting salaries will be between $315,000 and $336,000.
e. We are 98 percent confident that the regression equation can be used to make accurate predictions for placement scores between 315 and 336.

How many solutions does -2 + 5p + 10 = 10 + 3p have?
Answer:
Only 1 solution
Step-by-step explanation:
-2 + 5p + 10 = 10 + 3p
Subtract 10 from both sides:
-2 + 5p + 10 -10 = 10 + 3p- 10
Simplify:
-2+5p=3p
Add 2 to both sides:
-2+5p+2=3p+2
Subtract 3p from both sides:
5p-3p=3p+2-3p
simplify:
2p=2
Divide both sides by 2:
2p/2=2/2
Simplify:
p=1

How do I write “3 is less than a number”?
Answer:
3 - x
Step-by-step explanation:
Just think in order in bits.
3
So, write 3.
Less than = subtraction
So, write a subtraction symbol.
A number = a variable, such as x.
So, write a variable.
That will give you: 3 - x

Answer:
Radius = 7.5 cm
Diameter = 15cm
Step-by-step explanation:
Radius = 7.5 cm (because the slanting line is 7.5cm)
Diameter = Radius x 2
Diameter = 7.5 x 2
Diameter = 15 cm
Hope that helps!
what is the range of h
Answer:
-4 to 6
Step-by-step explanation:
The range is the y-axis, unlike the domain which is on the x-axis. So th points would go from -4, the lowest point, to 6 the highest point. If you need to specify, say intervals of 2 as -4 goes to -2, and 2 goes to 4.

Answer:
The two numbers are 45 and 46.
Step-by-step explanation:
Given: Sum of two numbers=91
To find: Two consecutive numbers which add up to form 91
Solution:
Consecutive numbers are those numbers which have a difference of one between them.
First divide 91 into two halves, we get 45.5
Now we know 45.5+45.5=91
But the numbers should differ by one in order for them to be consecutive.
Hence we subtract 0.5 to get one number and add 0.5 to get the second number from 45.5
So, the two numbers are 45.5–0.5=45
and 45.5+0.5=46
Hence the two numbers are 45 and 46.

which value of x makes the equation 12x -15 = 6 -3x
Answer:
x=7/5
Step-by-step explanation:
12x+3x=15+6
15x=21
x=7/5
Answer:
X= [tex]\frac{7}{5}[/tex]
Step-by-step explanation:
Ok...
Get ready to see Alot more numbers
1. Rearrange terms.
12x-15=6-3x
12x-15=-3x+6
2. Add 15 to both sides.
12−15=−3+6
12−15+15=−3+6+15
3. Simplify
If you add the numbers you will get:
12x=-3x+21
4. Add 3x to both sides of the equation.
12x=-3x+21
12x+3x=-3x+21+3x
5. Simplify
If you combine the like terms you will get,
15x=21
6. Divide both sides of the equation by the same term.
15x=21
[tex]\frac{15x}{15}[/tex] = [tex]\frac{21}{15}[/tex]
7. Simplify
If you cancel terms that are in both of the numerator and denominator, then divide the numbers you will get:
x= [tex]\frac{7}{5}[/tex]
