Answer:
I think u forgot to mention the question?
Step-by-step explanation:
Using a two-tailed test with an alpha of 0.05, a research reports an obtained Z-score of -2. The researcher should reject the null
hypothesis.
True
False
Since the absolute value of the z-score is greater than the critical value, the statement is true.
When do we reject or do not reject the null hypothesis?For a two-tailed test:
If the absolute value of the test statistic is less than the critical value, we do not reject the null hypothesis.If it is more, we reject.The critical value for a two-tailed test with [tex]\alpha = 0.05[/tex] is of |z| = 1.96.
In this problem, we have that Z = -2, hence |Z| = 2, which is greater than the critical value, hence we reject the null hypothesis and the statement is True.

The first two questions have to with understanding the meaning of the English words. (It's reading comprehension.)
__
(iv) "no larger than 10" means "less than or equal to 10"
(b) x ≤ 10
__
(v) "at most 1600" means "less than or equal to 1600"
(c) c ≤ 1600

Leslie earned $12 Friday, $20 Saturday, and $56 Sunday selling bracelets. If she sold each bracelet for the same amount of money what is the most she could charge for each bracelet?
Answer:
$4
Step-by-step explanation:
For this, you want to find the greatest common factor
This basically means what number can be divided out of all of these.
So, you can find the factors for all of them and find which one appears in all three numbers and which is the greatest number
for 12:
1, 2, 3, 4, 6, 12
For 20:
1, 2, 4, 5, 10, 20
For 56:
1, 2, 4, 7, 8, 14, 28, 56
The numbers that appear in all of there are:
1, 2, and 4
And since we want to find the greatest amount she can charge for bracelet, the answer is:
$4

Answer:
n = 7
Step-by-step explanation:
simplify the logs according to their bases
Answer:
n = 7
Step-by-step explanation:
[tex]\sf \log_4(64)^{n+1}=log_5(625)^{n-1}[/tex]
Change 64 to an exponent with base 4 and 625 to an exponent with base 5:
[tex]\implies \sf \log_4(4^3)^{n+1}=log_5(5^4)^{n-1}[/tex]
Using exponent rule [tex](a^b)^c=a^{bc}[/tex]
[tex]\implies \sf \log_4(4)^{3(n+1)}=log_5(5)^{4(n-1)}[/tex]
Using log rule: [tex]\log_a(b^c)=c \log_a(b)[/tex]
[tex]\implies \sf 3(n+1)\log_4(4)}=4(n-1)log_5(5)[/tex]
Using log rule: [tex]\sf \log_a(a)=1[/tex]
[tex]\implies \sf 3(n+1)=4(n-1)[/tex]
[tex]\implies \sf 3n+3=4n-4[/tex]
[tex]\implies \sf 3+4=4n-3n[/tex]
[tex]\implies \sf n=7[/tex]

3. Jenny puts two wooden blocks together. One block has a length of 5 in., a width of 4 in., and a
height of 5 in. The other block has a height of 4 in., a length of 5 in., and a width of 2 in. What is the
combined volume of the blocks?
Answer:
140 inches cubed
Step-by-step explanation:
Use the formula V = length * width * height to find the volumes of each block, then add them together to get the combined volume. So, (5 * 4 * 5) + (4 * 5 * 2) = 140 inches cubed, which is the combined volume.

Garrett buys a bag of cookies that contains 8 chocolate chip cookies, 6 peanut butter cookies, 7 sugar cookies and 7 oatmeal cookies. What is the probability that Garrett reaches in the bag and randomly selects a chocolate chip cookie from the bag, eats it, then reaches back in the bag and randomly selects an oatmeal cookie
Answer:
p(chocolate chip) = 2/7
p(oatmeal) = 7/27
Step-by-step explanation:
probability = favorable outcomes/total outcomes
First, add up all the cookies in the bag.
8 + 6 + 7 + 7 = 28
Next find the probability of selecting a chocolate chip cookie. Since there are 8 chocolate chip cookies and 28 cookies in the bag, create a fraction.
p(chocolate chip) = 8/28
reduce by 4
p(chocolate chip) = 2/7
Now that the cookie was eaten that will reduce the number of chocolate chip cookies to 7 and the overall number of cookies to 27.
There are 7 oatmeal cookies and 27 total cookies, so create the fraction.
p(oatmeal) = 7/27

D. 10 ft. by 21.25 ft.
Pls explain how u got the answer!
Answer:
D.
Step-by-step explanation:
We know that each centimeter is equal to 2.5 feet. The way I solved it was this.
We start with the 4cm. We can multiply 4×2.5, and that gives us 10 feet. We can do 8.5×2.5, and that will equal 21.25 feet. So the final and correct answer is D. 10 feet by 21.25 feet
