Which number line shows the solutions to n > -2?
please answer #3
i have only 5 points left ;(
Answer:
f(x) = 2,000(0.94)^x; 952 km^2
Step-by-step explanation:
Formula for exponential growth or decay:
f(x) = P(1 + r)^x
where
f(x) = future value in year x
P = present value
r = annual rate of growth (positive) or decrease (negative)
x = time in years
In this problem,
P = 2,000
r = -6% = -0.06; here r is negative since this is a decreasing function
The formula is
f(x) = 2,000(1 - 0.06)^x
f(x) = 2,000(0.94)^x
For year 12, x = 12.
f(x) = 2,000(0.94)^x
f(12) = 2,000(0.94)^12
f(12) = 952
Factor completely
w^2 + 12w -f^2+ 36
The IQ scores of the middle 50% of a population can be written as
I
100
15
where x is a person's IQ. Solve the inequality to find the IQ scores for the middle 50% of the population.
x 270 and x s 130
Ox570 and x 2 130
Oxs 90 and x 2 110
x 290 and x s 110
Complete question :
The IQ scores of the middle 50% of a population can be written as (x - 100) / 15 ≤ 2/3
Answer: 90 ≤ x ≤ 110
Oxs 90 and x 2 110
Step-by-step explanation:
Given the inequality:
The middle 50% of the population :
(x - 100) / 15 ≤ 2/3
The upper bound :
(x - 100) / 15 ≤ 2/3
multiply both sides by 15
(x - 100) / 15 * 15 ≤ 2/3 * 15
(x - 100) ≤ 2/3 * 15
x - 100 ≤ 10
x ≤ 10 + 100
x ≤ 110
The lower bound :
- (x - 100) / 15 ≤ 2/3
(-x + 100) / 15 ≤ 2/3
multiply both sides by 15
(-x + 100) / 15 * 15 ≤ 2/3 * 15
(-x + 100) ≤ 2/3 * 15
-x + 100 ≤ 10
-x ≤ 10 - 100
-x ≤ - 90
x ≤ 90
90 ≤ x ≤ 110

For this problem, 0.25 in = 50 m. So
11 in = (11 in) • (50/0.25 m/in) = 2200 m
Alternatively, if 0.25 in = 50 m, that means 1 in = 200 m. So 11 in = 11 (200 m) = 2200 m.

A team of five kids is randomly chosen from a class of 20 students. An outcome of the selection process is the set of five kids selected. What is the size of the same space
Answer:
[tex]S= 4[/tex]
Step-by-step explanation:
Given
[tex]Total = 20[/tex]
[tex]Selection = 5[/tex]
Required
Determine the size of sample space
Represent this with S
S is calculated by dividing the total number of kids by the number of selection.
[tex]S = \frac{Total}{Selection}[/tex]
[tex]S = \frac{20}{5}[/tex]
[tex]S= 4[/tex]
Hence, the sample space has a size of 4

in the term 4p, the variable p is raised to the power of 0 or 1 ?
Answer:
1
Step-by-step explanation:
anything raised to the power of 0 would equal 1 and p doesn't equal 1 here.
Answer:
4 or 0
Step-by-step explanation:
well if the variable p became 0 the term 4p would look more like this 4(0) or 4 * 0 making the answer be 0
If the variable was changed into 1 the term 4p would become 4(1) or 4 * 1 as of such the answer would be 4.
now if you are raising p to a 0 so the term is more like this: 4p to the power of 0 then your answer would be 1. Because p would change to 0.
Now if you had 4p to the raised power of 1 then your answer would be 4 because p was changed to a 4.
I hope this answers your question.

General form of a linear regression equation :
y = b1x + b0
b1 = slope ; b0 = intercept
Using an online regression calculator, the regression equation obtained is :
y = 5.8286 + 52.2286x
Comparing the equation ;
b1 = 52.23
b0 = 5.83
