x^3=27 what is the value of x?
Answer:
x = 3
Step-by-step explanation:
3*3*3 = 9*3 = 27
Step-by-step explanation:
Let's solve your equation step-by-step.
[tex]x^3 =27[/tex]
Step 1: Take cube root.
[tex]x = (27)^(1/3)[/tex]
[tex]x=3[/tex]
Explanation in words (Short Form)
- Move the variable to the left and the other values to the right to determine the value of x. To ascertain the outcome, simplify the values.
- In this equation (x^3=27), we can solve this equation by taking the cube root and then ascertaining the outcome. The answer will result as x = 3 at the end for the following equation: x^3=27 to finding the value for x.
Answer:
[tex]x=3[/tex]

A basketball league assigns 8 players to each team. How many players can sign up for the league if there are 24 teams?
Answer:
192
Step-by-step explanation:
If there are 8 players on a team, and a total of 24 teams, you will need to multiply 8 x 24 to find the answer.
8 x 24 = 192 players can sign up for the league.
(hope this helps can i plz have brainlist :D hehe)
Answer:
192 players
Step-by-step explanation:
8x24=192
8 is the 8 players per team, since there are 24 teams available, multiply 8 by 24.
You apply for a job and have to take a drug test. You are curious about the error rate for the test so you do some research. You find a study where 47 out of 382 test results using this test were wrong (either a false positive or a false negative). The company that produces the drug test claims that less than 14% of the test results are wrong. Test if this seems accurate.
Answer:
Test statistic Z = -1.0
|Z| = |-1.0| < 1.96 at 0.05 level of significance.
The null hypothesis is accepted
The company that produces the drug test claims that less than 14% of the test results are wrong
Step-by-step explanation:
Step(i):-
Given that the population proportion P = 14% =0.14
Given that the sample size 'n' = 382 tests
Given that find a study where 47 out of 382 test results using this test were wrong (either a false positive or a false negative).
Sample proportion
[tex]p = \frac{x}{n} = \frac{47}{382} = 0.1230[/tex]
Null hypothesis: H₀ : P = 0.14
Alternative Hypothesis:H₁ : P≠ 0.14
Step(ii):-
Test statistic
[tex]Z = \frac{p-P}{\sqrt{\frac{PQ}{n} } }[/tex]
[tex]Z = \frac{0.1230-0.14}{\sqrt{\frac{0.14 X0.86}{382} } }[/tex]
Z = - 1.0
|Z| = |-1.0| < 1.96 at 0.05 level of significance.
Final answer:-
The null hypothesis is accepted
The company that produces the drug test claims that less than 14% of the test results are wrong

O 116 miles
O 118 miles
120 miles
someone please help me answer this!
Answer:
72 mi is the answer.
Step-by-step explanation:
a = 30 mi
b = ?
c = 78 mi
According to the Pythagoras theorem,
a² + b² = c²
30² + b² = 78²
900 + b² = 6084
b² = 6084 - 900
b² = 5184
b = 72 mi
∴ the eastbound airplane has travelled 72 mi.

Answer:
120 square inches.
Step-by-step explanation:
This is a regular octagon. (It has 8 equal sides). You have enough information to find the area of 1 triangle.label the bottom line as 5.Draw two lines from the center to each end of the bottom 5 inch line.That gives you 1 triangle. Find the area of that 1 triangle.Area = 1/2 b * hb = 5h = 6Area = 1/2 * 5 * 6Area = 15.Now here's the actual answer.You have 8 such triangles. The area of the octagon is 8 * 15 = 120 square inches.

From Barbie dolls to runway models, women in Western countries are exposed to unrealistically thin and arguably unhealthy body standards for their gender. A body mass index (BMI) between 18.5 and 24.9 is considered healthy. Using a 3D computer avatar, participants built what they considered the ideal body of an adult of their own gender. Below appears a summary of the results for a sample of 40 female heterosexual Caucasian undergraduate students from British universities that had been recruited by the researchers. Mean BMI was recorded to be 18.85 with standard deviation 1.75. Does the data provide evidence that young Caucasian women in British Universities, on average, aim for an unhealthy ideal body type (corresponding to a BMI less than 18.5)? Use α = 0.10.
Required:
a. Construct a 99% confidence interval for the mean BMI for young Caucasian women in British universities using R. Use at least 2 decimals in your answer.
b. Would a 99% CI (for the mean BMI) constructed using a smaller sample than the one used for part a) tend to be wider or narrower? Explain.
Answer:
(18.1361 ; 19.5639) ;
using a smaller sample will widen the margin
Step-by-step explanation:
Given :
Xbar = 18.85
Standard deviation, s = 1.75
Sample size, n = 40
Confidence interval is obtained using the relation :
Xbar ± Margin of error
Margin of Error = Zcritical * s/ √n
Zcritical at 99% = 2.58
Margin of error = 2.58 * (1.75/√40) = 0.7139
Lower boundary = 18.85 - 0.7139 = 18.1361
Upper boundary = 18.85 + 0.7139 = 19.5639
(18.1361 ; 19.5639)
B.)
The sample size, n being the denominator in the margin error formula increases the error value as it reduces or decreases in value Hence widens the interval. Conversely, increasing the sample size reduces the error margin value and ultimately narrows the interval.
Therefore, using a smaller sample will widen the margin
Write an equation of the line below.
Answer (assuming it can be in slope-intercept form):
[tex]y = \frac{4}{5} x[/tex]
Step-by-step explanation:
1) First, find the slope of the line. Use the slope formula [tex]m = \frac{y_2-y_1 }{x_2-x_1}[/tex] and substitute the x and y values of two points on the line into it. We can see that the line passes through (0,0) and (5,4), so let's use those points for the formula and solve:
[tex]m = \frac{4-0}{5-0} \\m = \frac{4}{5}[/tex]
So, the slope is [tex]\frac{4}{5}[/tex].
2) Next, identify the y-intercept of the line. The y-intercept is the point at which the line intersects the y-axis. We can see that the line intersects the y-axis at (0,0), so that must be the y-intercept.
3) Now, write the equation of the line in slope-intercept form using the [tex]y = mx + b[/tex] format. The number in place of [tex]m[/tex] represents the slope, so substitute [tex]\frac{4}{5}[/tex] in its place. The number in place of [tex]b[/tex] represents the y-intercept, so substitute 0 in its place. This gives the following answer and equation:
[tex]y =\frac{4}{5} x+0\\y = \frac{4}{5} x[/tex]
Answer:
y=4/5x
Step-by-step explanation:
y=mx+b where m=slope and b=y-intercept
In this problem, the slope is 4/5 because m=rise/run.

Choose all of the statements that indicate long-term advantages in placing a larger down payment on a car loan received from a bank.
A). Using a larger down payment often results in lower interest rates on the loan for the vehicle.
B) The amount of money placed upfront on a car loan is usually rebated back to the borrower at the end of the loan.
C) Placing a larger down payment on the loan typically lessens the total amount required to be paid back on the loan.
Eliminate
D) Using a larger down payment creates a larger principal on the loan, meaning the interest paid on the loan will be smaller.
E) Putting down more money upfront on a loan allows more money to be invested elsewhere by the borrower during the length of the car loan.

Consider the line y=7x+4.
Find the equation of the line that is parallel to this line and passes through the point ( -3, 5)
Find the equation of the line that is perpendicular to this line and passes through the point ( -3, 5)
Answer:
parallel y=7x+26
perpendicular y=1/7x+32/7
Step-by-step explanation:
parallel line have the same slope
y-5=7(x-(-3))
y-5=7(x+3)
y-5=7x+21
y=7x+21+5
y=7x+26
perpendicular slope is the opposite of the original slope of 7
y-5=-1/7(x-(-3))
y-5=-1/7(x+3)
y-5=-1/7x-3/7
y=-1/7x-3/7+5
y=-1/7x+32/7

Answer:
90°-33°=57°
57=2x+1
-1. -1
56=2x divide both sides by 2
28=x
x =28
Answer:
x = 28
Step-by-step explanation:
Both of these would add up to 90 degrees.
Equation → 2x + 1 + 33 = 90
Add like terms → 2x + 34 = 90
Subtract both sides by 34 → 2x + 34 - 34 = 90 - 34
Divide both sides by 2 → 2x = 56
→ x = 28

After multiplying both the numerators and the denominators, it's time to simplify or
reduce your product.
Example: 2/5x3/4 = 6/20.
The greatest common factor of 6 and 20 is 2. We divide the top and bottom by 2, which
simplifies to 3/10.
What is the reduced product of 2/3 x 5/8?
A
10/24
B
5/12
С
1/2
D
10/12
Answer: The answer is B, 5/12.
hope this helped :)
Answer:
B. 5/12
Step-by-step explanation:
2/3 x 5/8 = 10/24
The greatest common factor of 10 and 24 is 2.
Since the GCF is 2,
We divide the numerator and denominator by 2 and get 5/12.
Therefore, the simplified fraction of 10/24 is 5/12.
