-2, 0, and 4
1. x=-2, x=0
So, the equation in factored form would be x(x+2)=0.
2. x=0, x=4
So, the equation in factored form would be x(x-4)=0.
3. x=-2, x=0, x=4

What is the explicit formula for the arithmetic sequence 4/5, 29/30, 17/15, 13/10?
Answer:
The answer is D,
a(n) = 4/5 + 1/6(n- 1)
just took the test :)
Step-by-step explanation:
The explicit formula for the arithmetic sequence is D, a(n) = 4/5 + 1/6(n- 1)
What is arithmetic sequence?An arithmetic sequence is sequence of integers with its adjacent terms differing with one common difference.
The explicit formula is given by:
[tex]T_n = a + (n-1)d[/tex]
Where a is the first term (4/5) and d is the common difference (the difference is any 2 terms).
Therefore, to find d:
29/30 - 4/5
29/30 - 24/30
d = 5/30
d = 1/6
Now putting them into the formula:
a(n) = 4/5 + 1/6(n- 1)
The last answer choice is right.

Answer:
13 units is the answer.
Step-by-step explanation:
points (8,-4) and (3,8)
We can rewrite the Pythagorean theorem as,
[tex]d=\sqrt{(x_2 - x_1)^2+(y_2-y_1)^2} \\\\d= \sqrt{(3-8)^2 + (8-(-4))^2} \\\\d=\sqrt{(-5)^2 + (12)^2} \\\\d=\sqrt{25 + 144} \\\\d=\sqrt{169} \\\\d=13\\\\[/tex]
∴ distance between 2 points (8,-4) and (3,8) = 13 units.

40% of the children are girls.
The ratio of adults to children is 2:3
How many of the children attending are boys?
Can someone plz help me with this
Answer:
1000 children
Step-by-step explanation:
Find the total units of adults and children = 2 + 3 = 5
5 units = 5000
1 unit = 5000 ÷ 5 = 1000
100% ÷ 5 units = 20% each unit
3 units = 20% x 3 = 60%
Since we all know that 60% of the people are children and 40% of the children are girls...
60 - 40 = 20%
20% = 1000

7. The following numerical ordered sequence of numbers has a mean of 13 and a median of 14. 4. a. 8. 10. 13.b. 16. 18. 20:21 Gven this information, the values of a ondo must be:
Answer:
a = 9
b = 19
Step-by-step explanation:
DO B FIRST
The mean is the average of all the terms (numbers) in the sequence
To find the average you find the sum of the terms and divided the sum by the number of terms there are.
The mean times the number of terms equals the sum of all the terms subtract the terms that you know from the sum to get A
a = 17(10)-7-12-15-17-19-20-22-24-25
a = 170-161
a = 9
The median is found by taking the average of the two middle terms
Our middle terms are 17 and B
the median times 2 equals the sum of the two terms and then subtract the term you know from the sum
b = 18(2)-17
b = 36-17
b = 19

what is the value of a when we rewrite 8^x as a^-x/9
Answer:
[tex]a = \frac{1}{134217728}[/tex]
Step-by-step explanation:
Given
[tex]8^x = a^{-x/9}[/tex]
Required
Find a
Take log of both sides
[tex]log(8^x) = log(a^{-x/9})[/tex]
Apply law of logarithm
[tex]x\ log(8) = (-x/9) log(a)[/tex]
Divide both sides by a
[tex]log(8) = -\frac{1}{9} log(a)[/tex]
Multiply both sides by -9
[tex]-9\ log(8) = log(a)[/tex]
Apply law of logarithm
[tex]log(8^{-9}) = log(a)[/tex]
Cancel out log
[tex]8^{-9} = a[/tex]
Rewrite as:
[tex]a = 8^{-9}[/tex]
Apply law of indices
[tex]a = \frac{1}{8^9}[/tex]
[tex]a = \frac{1}{134217728}[/tex]

Step-by-step explanation:
A university interested in tracking its honors program believes that the proportion of graduates with a GPA of 3.00 or below is less than 0.16. In a sample of 200 graduates, 24 students have a GPA of 3.00 or below. The value of the test statistic and its associated p-value at the 5% significance level are _________, respectively.
Answer:
The value of the test statistic and its associated p-value at the 5% significance level are -1.54 and 0.9382, respectively.
Step-by-step explanation:
A university interested in tracking its honors program believes that the proportion of graduates with a GPA of 3.00 or below is less than 0.16.
This means that the null hypothesis is:
[tex]H_{0}: p \geq 0.16[/tex]
Testing this hypothesis, means that the alternate hypothesis is:
[tex]H_{a}: p > 0.16[/tex]
The test statistic is:
[tex]z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]
In which X is the sample mean, [tex]\mu[/tex] is the value tested at the null hypothesis, [tex]\sigma[/tex] is the standard deviation and n is the size of the sample.
0.16 is tested at the null hypothesis:
This means that [tex]\mu = 0.16, \sigma = \sqrt{0.16*0.84}[/tex]
In a sample of 200 graduates, 24 students have a GPA of 3.00 or below.
This means that [tex]n = 200, X = \frac{24}{200} = 0.12[/tex]
Value of the test statistic:
[tex]z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]
[tex]z = \frac{0.12 - 0.16}{\frac{\sqrt{0.16*0.84}}{\sqrt{200}}}[/tex]
[tex]z = -1.54[/tex]
Pvalue:
The pvalue is the probability of finding a sample mean above 0.12, which is 1 subtracted by the pvalue of z = -1.54.
Looking at the z-table, z = -1.54 has a pvalue of 0.0618
1 - 0.0618 = 0.9382
The value of the test statistic and its associated p-value at the 5% significance level are -1.54 and 0.9382, respectively.

Ms. Wall will roll two number cubes. What is
the probability that she will roll a sum of 9 ?
Express your answer as a fraction.
(I'll give brainlist if u get it right)
Answer: 9/1
Step-by-step explanation: Apologies for the mistake. Let's calculate the probability again.
To find the probability of rolling a sum of 9 on two number cubes, we need to determine the number of favorable outcomes and divide it by the total number of possible outcomes.
For a sum of 9, the following combinations are favorable:
(3, 6), (4, 5), (5, 4), (6, 3)
So, there are 4 favorable outcomes.
The total number of possible outcomes is still 6 × 6 = 36.
The probability of rolling a sum of 9 is:
Probability = Number of favorable outcomes / Total number of possible outcomes
Probability = 4 / 36
Simplifying the fraction, we get:
Probability = 1 / 9
Therefore, the probability of rolling a sum of 9 is 1/9, not 11/18 as previously stated.
