Step-by-step explanation:
Find three consecutive integers such that the sum of the first two is three times the third.
Answer:
-3, -4, -5
Step-by-step explanation:
x = 1st integer
x+1 = 2nd integer
x+2 = 3rd integer
x+x+1 = 3(x+2)
2x + 1 = 3x + 6
1 = x + 6
-5 = x
-4 = x+1
-3 = x+2

Question 6
Write the first five terms of the geometric sequence where Q1
Sand r = 3
O {8, 24, 72, 216, 648}
O {8, , , ,
O {3, 24, 192, 1536, 9216}
O {8, 11, 14, 17, 20}
5 pt
Question 7
Answer:
{8, 24, 72, 216, 648}
Step-by-step explanation:
Geometric sequence:
In a geometric sequence, the quotient of consecutive terms is always the same, that is, each term is the previous term multiplied by the common ratio.
In this question:
First element is 8, common ratio of 3. So
Second term: 8*3 = 24
Third term: 24*3 = 72
Fourth term: 72*3 = 216
Fifth term: 216*3 = 648
So the answer is {8, 24, 72, 216, 648}
Does the point (3,25) lie on the line y = 6x + 7?
Answer
YesStep-by-step explanation:
Replace x and y
[tex](3 \: \: \: 25)[/tex]
[tex]y = 6x + 7 \\ 25 = 6 \times 3 + 7 \\ 25 = 18 + 7 \\ 25 = 25[/tex]
So, the point (3,25) lie on the line y=6x+7
hope this helps you.

Set D
Answer:
Set A
Step-by-step explanation:
A negative linear association will always have a negative slope , a negative association can also be be detected from the data given, as the y value will decrease as the x values increases or vice versa.
The plot of the set A is attached Below with a correlation of - 1, meaning a strong negative relationship exists between the x and y variables.

9) Solve the system of equations by substitution
y = 3x + 2
y = -2x + 12
Answer:
x= 2, y= 8
Step-by-step explanation:
y= 3x +2 -----(1)
y= -2x +12 -----(2)
Substitute (1) into (2):
3x +2= -2x +12
Move x terms to 1 side, constant to the other:
3x +2x= 12 -2
Simplify:
5x= 10
Divide both sides by 5:
x= 10 ÷5
x= 2
Substitute x=2 into (1):
y= 3(2) +2
y= 6 +2
y= 8

A doctor at a local hospital is interested in estimating the birth weight of infants. How large a sample must she select if she desires to be 90% confident that her estimate is within 4 ounces of the true mean
Answer:
The minimum sample size needed is [tex]n = (\frac{1.96\sqrt{\sigma}}{4})^2[/tex]. If n is a decimal number, it is rounded up to the next integer. [tex]\sigma[/tex] is the standard deviation of the population.
Step-by-step explanation:
We have that to find our [tex]\alpha[/tex] level, that is the subtraction of 1 by the confidence interval divided by 2. So:
[tex]\alpha = \frac{1 - 0.9}{2} = 0.05[/tex]
Now, we have to find z in the Z-table as such z has a p-value of [tex]1 - \alpha[/tex].
That is z with a pvalue of [tex]1 - 0.05 = 0.95[/tex], so Z = 1.645.
Now, find the margin of error M as such
[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]
In which [tex]\sigma[/tex] is the standard deviation of the population and n is the size of the sample.
How large a sample must she select if she desires to be 90% confident that her estimate is within 4 ounces of the true mean?
A sample of n is needed, and n is found when M = 4. So
[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]
[tex]4 = 1.96\frac{\sigma}{\sqrt{n}}[/tex]
[tex]4\sqrt{n} = 1.96\sqrt{\sigma}[/tex]
[tex]\sqrt{n} = \frac{1.96\sqrt{\sigma}}{4}[/tex]
[tex](\sqrt{n})^2 = (\frac{1.96\sqrt{\sigma}}{4})^2[/tex]
[tex]n = (\frac{1.96\sqrt{\sigma}}{4})^2[/tex]
The minimum sample size needed is [tex]n = (\frac{1.96\sqrt{\sigma}}{4})^2[/tex]. If n is a decimal number, it is rounded up to the next integer. [tex]\sigma[/tex] is the standard deviation of the population.

URGENT!! Use the compound interest formula A = P(1 + i)^n. Evaluate,
$1200 at 8.4% per year, compounded semi-annually, for 3 years 6 months
Answer:
$38,025.04
Step-by-step explanation:
First, convert R as a percent to r as a decimal
r = R/100
r = 8.4/100
r = 0.084 rate per year,
Then solve the equation for A
A = P(1 + r/n)nt
A = 1,200.00(1 + 0.084/2)(2)(42)
A = 1,200.00(1 + 0.042)(84)
A = $38,025.04

Challenge: Solve the following equation by completing the square and enter the answers from below from least to great.
Equation: x(2)+16x+62=7
Results: x= {____ , _____}
Answer:
Step-by-step explanation:
To begin, get everything but the x terms on one side of the equation by subtracting the 62. That gives us
[tex]x^2+16x=-55[/tex]
Next, take half the linear term, square it, and add it to both sides. Our linear term is 16. Half of 16 is 8, and 8 squared is 6, so add 64 to both sides:
[tex]x^2+16x+64=9[/tex]
The reason we do this is to get a perfect square binomial on the left, which looks like this:
[tex](x+8)^2=9[/tex]. Undo the squaring on the left by taking the square root of both sides. Doing this leaves x + 8 on the left, but + or - 3 on the right:
x + 8 = 3 and x + 8 = -3. Solving each of these equations gives you your 2 solutions:
x = -5 and x = -11

Jeremy needs to buy three pieces of wood to make a triangular frame. If the wood is cut in 1 l- foot increments, which set of wood length will form a triangle?
What is the square root of -1?
Find the area of this figure
Answer:
90ft²
Step-by-step explanation:
Figure shown is a triangle
Area of a triangle = ( base length times height ) divided by 2
The triangle has a given height of 12 ft and a given base length of 15 ft
Hence area = ( 12 * 15 ) / 2
12 * 15 = 180
180 / 2 = 90
area = 90ft²
Answer:
Area is 90 degrees.
Step-by-step explanation:
The formula for the area of a triangle is (h*b)/2=A
We know height is 12.
We know base is 15.
So lets plug these in:
(12*15)/2=A
180/2=A
90=A
So 90 is our answer!
Hope this helps!

When rolling a standard 6-sided die, what is the probability of rolling an odd number and then rolling a number greater than 1?
Answer:
You multiply the probabilities together. The probability of rolling an odd number is 1/2 (because half of the numbers on a number cube are odd). The probability of rolling a number greater than 1 is 5/6 because 5 of the 6 numbers are greater than 1. Then multiply those two fractions together to get your answer.
Step-by-step explanation:
Which sequence can be defined by the recursive formula f(1) = 4, f (n + 1) = f(n) - 1.25 for n 2 1?
O 1,-0.25,-1.5, -2.75, -4,...
O 1, 2.25, 3.5, 4.75, 6, ...
O 4,2.75, 1.5, 0.25,-1, ...
O 4,5.25, 6.5, 7.75, 8, ...
Answer:
the third option
4, 2.75, 1.5, 0.25, -1, -2.25, ...
Step-by-step explanation:
the first value in the sequence is 4.
that eliminates already answer options 1 and 2.
and the values are going down, as we continuously subtract 1.25 from the previous sequence number.
but answer option 4 shows a sequence, where the values go up.
so, only option 3 remains and is correct
4-1.25 = 2.75
2.75-1.25 = 1.5
1.5-1.25 = 0.25
0.25-1.25 = -1
