Answer:105.7
Step-by-step explanation: 1.51 times 70
Answer:
[tex]151\% \: of \: 70 \\ \frac{151}{100} \times 70 \\ \boxed{105.7}[/tex]
105.7 is the right answer.Solve for the roots in simplest form using the quadratic formula:
4x^2 -28x= -53
Answer:
x = (28 +- root -64) / (8)
Step-by-step explanation:
4x^2 -28x= -53 = 0
x = [-(-28)+- root (-28)^2 - 4 * 4 * 53] / 2 *4
x = (28 +- root 784 - 848) / (8)
x = (28 +- root -64) / (8)

g Which statement is correct? Group of answer choices A sample size of 1 is never acceptable. Judgment sampling is preferred to systematic sampling. Cluster sampling is useful when strata characteristics are unknown. Sampling without replacement introduces bias in our estimates of parameters.
Answer:
A sample size of 1 is never acceptable
Explanation:
A sample size of 1 is simply not statistically significant enough as to reach close to accurate conclusions based on sample data. Statistical tests using just one data point may not be enough to test data variability. Axrule of thumb or best practice is to have at least 10% sample size from the population. It is advised to have at least a sample size of 100 sayvpopulation is 1000 to be able to reach more valid conclusions from sample data.

Jeffrey is 5 years older than his brother. If j represents Jeffrey’s age, the expression j−5 can be used to find his brother’s age. If Jeffrey is 23, how old is his brother?
If j=23 and j-5 is how old Jeffery's brother is then Jeffrey's brother is 17 years old.
So j=17

x=y-8;5x+y=-4
Step: Solve x=y−8for x:
Step: Substitute y−8 for x in 5x+y=−4:
5x+y=−4
5(y−8)+y=−4
6y−40=−4(Simplify both sides of the equation)
6y−40+40=−4+40(Add 40 to both sides)
6y=36
6y /6 = 36/ 6 (Divide both sides by 6)
y=6
Step: Substitute6foryinx=y−8:
x=y−8
x=6−8
x=−2 (Simplify both sides of the equation)
x=−2 and y=6
I hope this helps:

PLEASE HELP!! WHAT IS x???
9514 1404 393
Answer:
x = 90 degrees
Step-by-step explanation:
There are several ways to go about this (as is often the case with math problems). Here, we'll use the fact that an inscribed angle is half the measure of the arc it intercepts.
arc DE = 2×∠DFE = 60°
arc EF = 2×∠ECF = 60°
arc CF = 2×∠CEF = 60°
Then arc DEC is ...
arc DEC = arc DE +arc EF +arc FC = 60° +60° +60° = 180°
Angle DBC is half the measure of this arc, so is ...
∠DBC = 180°/2 = 90° = x
