4/5 z = 2/7
7×4×z = 2× 5 (move the denominator of both fractions to the other side)
28z = 10
z = 10 ÷ 28
z = 5/14
Answer: The answer your looking for is 5/14
Step-by-step explanation: You want to leave the variable alone, so you divide both sides by 4/5. If you divide 2/7 by 4/5, you get 5/14.

Answer:
Option B. 4
Step-by-step explanation:
From the question given above, the following data were obtained:
Angle θ = 60 °
Opposite (Fe) = 4√3
Adjacent (DE) = x
The value of x can be obtained by using the Tan ratio as illustrated below:
Tan θ = Opposite / Adjacent
Tan 60 = 4√3 / x
√3 = 4√3 / x
Cross multiply
√3 × x = 4√3
Divide both side by √3
x = 4√3 /√3
x = 4
Thus, the length of DE is 4

Answers
Answer:
36 is the HCF of 108 and 72
Answer:
36.
Step-by-step explanation:
HCF of 108 and 72
108 = 2 * 2 * 3 * 3 * 3
72 = 2 * 2 * 2 * 3 * 3
So picking out the common factors we have
HCF = 2 * 2 & 3 * 3
= 4 * 9

Answers
Answer:
Step-by-step explanation:
hello :
An = 10 -10/2^n
the first 4 terms are :
A1 = 10 -10/2^1 = 10-5
A1 = 5
A2 = 10 -10/2^2 = 10-10/4 = 10-5/2 = (20-5)/2
A2 = 15/2
A3 = 10 -10/2^3 = 10-10/8 =10- 5/4 = (40-5)/4
A3 = 35/4
A4 = 10 -10/2^4 = 10-10/16 = 10-5/8 = (80-5)/8
A4 = 75/8

An economist conducts a nationwide survey to study the financial perceptions of US adults. Specifically, he asks a random sample of 1,000 US adults: “Financially, are you doing OK or are you struggling to get by?” The results of the survey show that 829 of the 1,000 participants said they are doing OK.
(a) Construct a 95% confidence interval for the proportion of US adults who would say they are doing OK.
(b) Shortly thereafter, a similar study is conducted in Mexico with the intention of constructing a 95% confidence interval for the proportion of Mexican adults who would say they are doing OK. What is the smallest sample size that can be used to guarantee that the margin of error will be less than or equal to 0.01?

Hjqjzjzj is a complete* of the following elements has the largest atomic size in the world is the difference between human rights
Answer:
We know:
A+2B=777
2A+B=789
Let's rearrange the first equation to solve for A:
A=777-2B
Now let's plug 777-2B in for A in the second equation, and solve for B:
2(777-2B)+B=789
1554-4B+B=789
1554-789=3B
765=3B
B=255
Now we can substitute 255 in for B in the first rearranged equation, and solve for A:
A=777-2(255)
A=777-510
A=267
So candy bar A has 267 calories, and candy bar B has 255

A marine biologist wants to estimate the average weight of a population of dolphins living in a certain region of the ocean. The biologist will collect a random sample of dolphins and use the sample weights to create the estimate Which of the following is an appropriate method for the biologist to use for inference to the population?
A A one-sample t-interval for a population mean
B A one-sample t-interval for a sample mean
C A one-sample 2-interval for a population proportion
D A matched-pairs t-interval for a mean difference
E A two-sample t-interval for a difference between means
Answers
Answer:
A A one-sample t-interval for a population mean
Step-by-step explanation:
The biologist will collect a random sample of dolphins and use the sample weights to create the estimate.
In a confidence interval, we take the data from the sample and want to estimate it for the entire population, so the interval is for a population mean.
The standard deviation will be taken from the sample, which means that the t-interval is used.
We want for one population, so it is a one sample for the population mean, and the correct answer is given by option A.

1. 7x + 2 = 5x + 22 (alternate interior angles are congruent)
Collect like terms
7x - 5x = -2 + 22
2x = 20
2x/2 = 20/2
x = 10
2. 13x - 6 = 10x + 24 (alternate interior angles are congruent)
Collect like terms
13x - 10x = 6 + 24
3x = 30
3x/3 = 30/3
x = 10
3. (12x + 26)° + 46° = 180° (same side interior angles are supplementary)
12x + 26 + 46 = 180
12x + 72 = 180
12x + 72 - 72 = 180 - 72
12x = 108
12x/12 = 108/12
x = 9
4. (5x + 5)° + 135° = 180° (same side interior angles are supplementary)
5x + 5 + 135 = 180
5x + 140 = 180
5x + 140 - 140 = 180 - 140
5x = 40
5x/5 = 40/5
x = 8

That means we can solve for y using the trigonometric function of tangent.

Multiply by 600 to both sides, then use a calculator to solve.

Fifteen students were registered in Section 1 and 15 students were registered in Section 2 of a research course. They took the same midterm exam, and their exam scores were distributed as follows: Section 1: 89, 56, 45, 78, 98, 45, 55, 77, 88, 99, 98, 97, 54, 34, 94 Section 2: 77, 88, 87, 67, 98, 87, 55, 77, 45, 44, 88, 99, 69, 67, 98 a.

Answers
Answer:
a)

Mode : 67 , 77 , 87 , 88 , 98
Median - 77
Mean - 76.4
Range - 55
Variance - 333.11
Standard Deviation - 18.25
b)
Section 2 did better overall on the exam
Step-by-step explanation:
As given,
Section 1: 89, 56, 45, 78, 98, 45, 55, 77, 88, 99, 98, 97, 54, 34, 94
Section 2: 77, 88, 87, 67, 98, 87, 55, 77, 45, 44, 88, 99, 69, 67, 98
a)
For Section 1 -
Mode : 45 , 98
Median - 78
Mean - 73.8
Range - 65
Variance - 537.03
Standard Deviation - 23.17

Median - 77
Mean - 76.4
Range - 55
Variance - 333.11
Standard Deviation - 18.25
b)
As,
Standard deviation of section 2 < Standard deviation of section 1
⇒ Students of Section 2 are more consistent.
Also,
mean of Section 2 > mean of Section 1,
⇒average score of Section 2 student > Average score of Section 1 student.
∴ we get
Section 2 did better overall on the exam.
