Step-by-step explanation:
5(2x-3)=24
Distribute
10x -15 = 24
Add 15 to each side

Answers
Answer:
Option 2
Step-by-step explanation:
If you multiply 2 by 2 you get 4. If you multiply 3 by 2 you get 6. If you multiply 4 by 2, you get 8. If you multiply 5 by 2 you get 10. A proportional relationship is where you can multiply all the numbers by a certain number to get the answer. In this case, all the numbers in the left column could get multiplied by 2 to get the number in the right column.
In a mid-size company, the distribution of the number of phone calls answered each day by each of the 12 receptionists is bell-shaped and has a mean of 48 and a standard deviation of 9. Using the Standard Deviation Rule (as presented in the book), what is the approximate percentage of daily phone calls numbering between 30 and 66?
Answers
Answer:
95.44%
Step-by-step explanation:
Mean (m) = 48
Standard deviation (sd) = 9
n = 12
Zscore = (x - m) /sd
X = 30
Zscore = (30 - 48) / 9
Zscore = - 2
X = 66
Zscore = (66 - 48) / 9
Zscore = 2
percentage of daily phone calls numbering between 30 and 66 = P(z < 2) - p(z < - 2)
P(z < 2) = 0.9772
P(z < - 2) = 0.0228
Hence,
0.9772 - 0.0228 = 0.9544
0.9544 * 100% = 95.44

Answer:
∠3 and ∠2
Step-by-step explanation:
Adjacent angles are angles that have a common side and common vertex which each other.
The first option is incorrect because they don't share a common side. They do share a vertex but that isn't enough to call them adjacent.
The second option is correct because they share a common side and vertex.
The third option is incorrect because they don't share a common side.
The fourth option is incorrect because they don't share a common side. These two angles are congruent and opposite angles.

6. A set of data points has a correlation coefficient r = -0.86. Your friend claims
that because the correlation coefficient is close to -1, it is reasonable to use the
line of best fit to make predictions. Is your friend correct? Explain your reasoning.
Answers
Answer:
Yes
Step-by-step explanation:
The line of best fit is used in linear regression models to make predictions, the line of best fit gives the relationship between the dependent and independent variables by obtaining the Coefficient of correlation. The Coefficient of correlation is a value which ranges from - 1 to 1. With values close to either - 1 or 1 depicting a strong negative and positive relationship respectively. Hence, with a correlation Coefficient of - 0.86, which signifies a strong negative relationship, then we can go ahead and make prediction using the model.

Answer:
Perimeter is all sides added together, while Area is one side height times length
Step-by-step explanation:
Since your shape is a square all sides are equal so the equation is the same for all sides
Perimeter = 4z+3+4z+3+4z+3+4z+3 or (4z+3)4
14z+12 <= answer for perimeter
Area = (4z+3) (4z+3)
16z^2+12z+12z+9
16z^2+24z+9 <= answer for area

Answers
16 square feet (also can be written with an exponent 2 as in 16 ft^2)
Cube root of 64 is 4.
Why cube root? Because you need to multiply three numbers to get volume ( length, width, height.)
4x4 is 16.
Area, so you have to add the square feet

Answers
Answer:
5 years
Step-by-step explanation:
1. if able's age is x, then his sister's is x-4, and his brother's is 2x
2. if these sum to 32, then we can formulate the equation x+(x-4)+2x=32
3. now solve for x, 4x-4=32, 4x=36, x=9
4. if able's sister is x-4 years old, she is 9-4, or 5 years old
