Answer:
c*(t)-((t-2)*(t+6)*(t-4))=0
Step-by-step explanation:
ct - ((t - 2) • (t + 6) • (t - 4)) = 0
ct - (t - 2) • (t + 6) • (t - 4) = 0
3.1 ct-t3+28t-48 is not a perfect cube
ct - t3 + 28t - 48 = 0
Solve ct-t3+28t-48 = 0
how do you calculate the standard error of the mean in SPSS?
Answer:
Hope this helps
Step-by-step explanation:
Std Error Mean – Standard Error Mean is the estimated standard deviation of the sample mean. This value is estimated as the standard deviation of one sample divided by the square root of sample size: 9.47859/sqrt(200) = . 67024, 10.25294/sqrt(200) = . 72499.
In Mr. Walker's 7th grade class, the 30 students created a pie chart showing their choices for favorite pet. Based on the class findings, how many students chose cat as their favorite pet? Explain.
A) 6
B) 10
C) 3
D) 9
Answer:
D - 9 students
Step-by-step explanation:
For this problem, you need to find the percentage of students left. Subtracting all the percentages you already know, you get 100 - 30 - 20 - 10 - 10, or 30. Since there are 30 students in the class, 30 percent of 30 is 9 students.

How long will it take for an investment of $9000 to double at 4% Interest compounded continuously? Round to the nearest tenth of a year.
Which equation can be used to find the length of AC?
Answer:
10*sin(40)=AC
Step-by-step explanation:
[tex]sin(x)=\frac{opposite}{hypotenuse}[/tex]
so
here it says
[tex]sin(40)=\frac{AC}{10}[/tex] multiply both sides by 10
[tex]10*sin(40)=AC[/tex]
answer quick pls!
Jose wants to plan a skate party for his younger cousin's birthday. Skate Land charges a $65 flat fee and $7.50 per person.
Skate Land uses the equation C = 7.50p + 65 (C = total cost; p = number of people ) to calculate the total cost
based on the number of people attending. Find the total cost, C, of the birthday party if Jose invites 30 friends and family
members.
Answer:
$290
Step-by-step explanation:
We can use the equation that Skate Land created to find the total cost
C = 7.50p + 65
p = people so if we have 30 people, we have to solve 7.50 x 30
C = 225 + 65
we can now add the flat fee of $65 to get the total cost for the birthday part
C = $290

Answer:
2 -- True
0 -- True
-3 -- True
-4 -- False
-6 -- False
Step-by-step explanation:
When solved the inequality, 3x + 7 > -5, it would turn out to be x > -4
Anything greater than -4 is a solution.

Answer:
x = 5 / 3 = 1.667
Step-by-step explanation:
8*x+10-5*x-(15)=0
Solve : 3x-5 = 0
Add 5 to both sides of the equation :
3x = 5
Divide both sides of the equation by 3:
x = 5/3 = 1.667
x = 5/3 = 1.667
In a recent Super Bowl, a TV network predicted that 25 % of the audience would express an interest in seeing one of its forthcoming television shows. The network ran commercials for these shows during the Super Bowl. The day after the Super Bowl, and Advertising Group sampled 150 people who saw the commercials and found that 30 of them said they would watch one of the television shows. Suppose you have the following null and alternative hypotheses for a test you are running:
H0:p=0.53H0:p=0.53
Ha:p≠0.53Ha:p≠0.53Calculate the test statistic.
Answer:
The right solution is "-8.25".
Step-by-step explanation:
The given values are:
Sampled people,
n = 150
Null and alternative hypotheses will be:
[tex]H_0:p=0.53[/tex]
[tex]Ha:p\neq 0.53[/tex]
The z-statistics will be:
⇒ [tex]z=\frac{\bar{p}-p_0}{\sqrt{\frac{p_0(1-p_0)}{n} } }[/tex]
On substituting the values, we get
⇒ [tex]=\frac{0.2-0.53}{\sqrt{\frac{0.53(1-0.53)}{150} } }[/tex]
⇒ [tex]=\frac{-0.33}{\sqrt{\frac{0.24}{150}} }[/tex]
⇒ [tex]=\frac{-0.33}{0.04}[/tex]
⇒ [tex]=-8.25[/tex]

x =5 and z = 4 z2 - 2x
Answer:
Whenever you see a letter beside a number, just know you should multiply that number by the letter. So z = 4, then 2z = 2×4, and x = 5, then 2× 5.
so : 2×4 = 8 - 2×5
so : 8-10
so the answer would then be -2.

Which of the following is equivalent to the complex number i24?
Answer: 1
Step-by-step explanation:
Rewrite as (i^4)^6
Rewrite i^4 as 1
Rewrite i^4 as (i^2) ^2
((i^2)) ^2)6
Rewrite i^2 as -1
((-1) ^2) 6
Raise -1 to the power of 2
1^6
One to any power is 1.
Using the same triangle as above, calculate the area of the triangle. You must show TWO methods for calculating the area of the triangle. Round both answers to nearest tenth. Hint: you should be using the same values you provided in question 3 and you can use any values you calculated in question 3 as well.
Answer:
Step-by-step explanation:
Area of a triangle is 1/2 * b * h
b = base, the one labeled b on the diagram
h = height, the dotted line in the middle
so, you do pythagorean theorem with a and b to find the dotted line
a² + b² = h² (h is for height)
h = [tex]\sqrt{a^{2} +b^{2}}[/tex]
Then, you just plug in the numbers from question 3 to find h and then you do
1/2 * b * h
plzzzzzzzzzzzzzzzz SOLVE THE PIc
Answer:
The area is 72.
Step-by-step explanation:
2 * 6 = 12
