Answer: z = 1/2
Step-by-step explanation: subtract 6 from both sides to get 2z=1 divide both sides by 2, you get z = 1/2 check by inputting 1/2 for z
2(1/2)+6= 7
1/2 of 2 is 1
1+6=7
it checks out :)
Answer: z= 1/2
explanation:
if 7=2z+6, z would be 1/2, because 2 times 1/2=1. then 6+1 s equal to 7

Solve the linear equation 1/3x - 5 + 171 = x
Answer: x = 249
Step-by-step explanation:
(6x^2+3x) + (x^2 - 4x -3)
plz help
Answer:
7x^2 - x -3
Step-by-step explanation:
(6x^2+3x) + (x^2 - 4x -3)
We have to use distributive property first to get rid of the parenthesis, so you simply have to multiply the positive (+) symbol with everything inside the second set of parenthesis.
+ * x^2 = x^2
+ * -4x = -4x
+ * -3 = -3
Now, we rewrite the equation which is
6x^2 + 3x + x^2 - 4x -3
Now you simply combine like terms.
6x^2 + x^2 = 7x^2
3x-4x = -x
The answer will be
7x^2 - x -3
Hope this helps!!

A rectangle has a length of (x + 3) centimeters and a width of image x centimeters. If the perimeter is 24 centimeters, what is the length of the rectangle? A. 9 cm B. 3 cm C. 14 cm D. 7 cm PLEASE HELP WILL MARK BRAINLIEST.
Answer:
The length of the rectangle is 9 cm.
Step-by-step explanation:
Given: The length of rectangle(l) = (x+3) cm and a width of rectangle (w) = cm a
Also, perimeter of rectangle is 24 cm.
Perimeter of rectangle is to add the lengths of all the four sides.
Perimeter of rectangle (P) is given by;
P=2(l+w)
Substituting the value of P = 24 cm , l = (x+3) cm and w =
then,
Divide by 2 both sides of an equation;
Combine like terms;
Subtract 3 from both the sides we get;
Simplify:
Multiply both sides by we get
Therefore, length of rectangle(l) = (x+3) = 6+3 = 9 cm

Mrs.Davis deposits $8,000 into each of 2 savings accounts account 1 earns 6.5% simple interest account 2 earns earns 3% simple interest what’s the difference between the amounts of interest in account 1 and account 2 after 6 years?
Answer:
$1680
Step-by-step explanation:
The equation for simple interest is I = PRT, where I = interest earned, P = principal/amount invested, R = rate as a decimal, and T = time in years.
Account 1:
I = (8000)(0.065)(6)
I = $3,120
Account 2:
I = (8000)(0.03)(6)
I = $1,440
$3120 - $1440 = $1680

Answer:
its in a graph?
Step-by-step explanation:
There is a 0.9987 probability that a randomly selected 31-year-old male lives through the year. A life insurance company charges $186 for insuring that the male will live through the year. If the male does not survive the year, the policy pays out $100,000 as a death benefit. Complete parts (a) through (c) below.
Parts a through c is missing and it is;
a) From the perspective of the 33-year-old male, what are the monetary values corresponding to the two events of surving the year and not surviving?
The value corresponding to surviving the year is $_____.
The value corresponding to not surviving the year is $_____.
b) If the 33-year-old male purchases the policy, what is his expected value?
The expected value is $_____.
c) Can the insurance company expect to make a profit from many such policies? Why?
_____ because the insurance company expects to make an average profit of $_____ on every 33-year-old male it insures for 1 year.
Answer:
A) the value that corresponds to surviving the year = - $186
The value corresponding to not surviving the year = $99814
B) μ = -$56
C) Yes, the company can make a profit from many such policies because it makes an average profit of $56 on every 31 year old male it insures for 1 year.
Step-by-step explanation:
A) The company charges $186 for insuring. Thus;
Amount paid out = - $186
Therefore, the value that corresponds to surviving the year = - $186
Therefore, the value corresponding to not surviving the year = $100000 - $186
The value corresponding to not surviving the year = $99814
B) since probability that a 31 year old male survives is 0.9987, then;
Probability that a male doesn't survive is;
P(doesn't survive) = 1 - 0.9987
P(doesn't survive) = 0.0013
The expected value is calculated from;
μ = Σx•P(x) = (0.0013 × 99814) + (-186 × 0.9987)
μ = -$56
C) Yes, the company can make a profit from many such policies because it makes an average profit of $56 on every 31 year old male it insures for 1 year.
PLS HELP BY TOMORROW!A dice has sides numbered 1-6. What is the probability of landing of double threes?
Answer:
1/6
The probability of rolling a specific number twice in a row is indeed 1/36, because you have a 1/6 chance of getting that number on each of two rolls (1/6 x 1/6). The probability of rolling any number twice in a row is 1/6, because there are six ways to roll a specific number twice in a row (6 x 1/36).
Answer:
0.46% I think I got it wrong and I'm kinda sure bout it
Step-by-step explanation:
So on any turn, the probability of rolling a double is 6/36 = 1/6. Now each roll of the dice is independent. So the probability that any given turn will result in the rolling of doubles three times in a row is (1/6) x (1/6) x (1/6) = 1/216. This is approximately 0.46%

Researchers would like to assess the overall health of white pine trees in a state park. Using a computer program,
the researchers selected 100 random points in the state park and assessed the trees closest to the selected
points. Of the 100 trees selected, 24 showed damage to their lower limbs. Which of the following describes the
sample in this setting?
all white pine trees in the world
the 24 trees that showed damage
the 100 trees checked for damage
all white pine trees in the state park
Anyways,
the sample is the 100 trees checked. Thats cause they checked all 100 and found 24 had damage. Which means they sampled 100 trees out of the whatever amount in the forest.

Separate question since people are confused about it in the previous answers comments "Which of the following statements best describes the bias that may arise from the results?":
I can confirm A is wrong. C just, feels wrong completely.
So that leaves us with B or D.
I think it's D: Trees near the road may have more damage than trees away from it, so the results may overestimate the overall damage of the trees.
I have not finished yet but I am 95% sure D is correct.
The reason why I don't believe it's B is because they want to resample near the same road, which can still result to biased results.

Among all the given descriptions, the one that is describing the sample in the given setting is: “all white pine trees in the state park.” Hence, Option D is correct.
What is the meaning of the term “sample”?
A sample is merely a subset of the population. Consider a scenario in which one wished to determine the average income for all Americans in the population. In terms of research, a sample is a collection of individuals, things, or things that are taken for measurement from a wider population.
To ensure that the findings from the research sample can be applied to the population as a whole, the sample should be representative of the population. 100 trees that were examined are the sample.
That's because they examined all 100 and discovered that 24 had damage, which means that they took 100 samples from the total number of trees in the forest.
The findings may exaggerate the total extent of the damage to the trees since trees close to the road may have sustained more damage than those farther away from it.
Therefore, Option D is correct.
