Answer:
y=3/2x-17
Step-by-step explanation:
y-y1=m(x-x1)
y-(-5)=3/2(x-8)
y+5=3/2(x-8)
y=3/2x-24/2-5
y=3/2x-12-5
y=3/2x-17

Step-by-step explanation:
We can create the equation step-by-step:
Each row of bricks is 6.5cm and the number of row of bricks is r: 6.5r
Total of height of wall: = 259cm
Top row is 1cm shorter: -1cm
Combine all the terms together and we get: 6.5r - 1 = 259
Which means each row of bricks is 6.5cm but minus 1cm from the top to get 259cm the total :D

one bar of candy A and two bars of candy B have 769 calories. Two bars of candy A and one bar of candy B contain 776 calories. Find the caloric content of each candy bar.
Step-by-step explanation:
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
I Hope it helps

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
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.

What geometric term describes PQ and RS
Answer:
perpendicular lines
Step-by-step explanation:
Two lines in a plane are said to be perpendicular if they intersect in such a way that the angles formed between them are right angles. In the adjoining e, lines PQ and RS intersect at 0 such that ∠ROQ = ∠ ROP = ∠POS = ∠QOS = 90°. Therefore, we say that PQ is perpendicular to RS

Find the H.C.E of 108 and 72.
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
= 36.

In the diagram below, which distance represents the distance from point Qto
RS?
Answer:
QT
Step-by-step explanation:
Given
The attached diagram
Required
Which distance represents Q to RS
The distance from Q to RS is determined by drawing a perpendicular line from Q to RS.
From the diagram, the perpendicular from Q to RS meets RS at point T.
Hence, the required distance is represented by QT
A. 2 sqrt 3
B. 4
C. 8
D. 4 sqrt 6
E. 12
Please help
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
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?
Answer:
a) (0.806, 0.852)
b)Margin of error ≤ 0.01
1.96*√{0.5*(1–0.5)/n} ≤ 0.01
√n ≥ 98
n ≥ 9604
• Smallest sample size = 9604

a statement for the equation p-6=10
Answer:
See Explanation
Step-by-step explanation:
Given
[tex]p - 6 = 10[/tex]
Required
Write a statement for the expression
The statement is:
The cost of a grater is $6 less than the cost of an electric cooker, What is the of the electric cooker?
The above statement when translated to a mathematical expression is:
[tex]p - 6 = 10[/tex]
Where p represents the cost of the cooker
Solving for p.
[tex]p = 10 + 6 = 16[/tex]
what is the purpose of the dx in the integral ∫2x dx?
Answer:
[tex]dx[/tex] denotes an infinitesimal displacement along [tex]x[/tex]
Step-by-step explanation:
The integration refers to the antiderivative of a function. The inverse process of differentiation is the integration.
The integration is used to find the volume and area under the curve.
In ∫ [tex]2x\,\,dx[/tex]
∫ denotes the sign of integral,
[tex]dx[/tex] denotes an infinitesimal displacement along [tex]x[/tex],
[tex]2x[/tex] is the part to be integrated.
