Answer:
1 hour
Step-by-step explanation:
Equation: 6 hours × 1/6 hours = 1 hour
If there are 6 hours and Tamela missed 1/6, that means she missed 1 hour of school.

Answer: 16
Step-by-step explanation:
All you have to do is plug 3.2 into the expression. So 5 * 3.2 is 16.
Help me out in this question please
20
Step-by-step explanation:There are two ways to solve this (both will end up with the same answer):
1st way:
You can find 4/9 of 36 to find how many displays the class explored so far. You can write it as 4/9 x 36, which is equal to 16. So, the class explored 16 displays so far. All you need to do is subtract 16 from 36 to find how many displays the class needs to explore, which can be written as 36-16, and is equal to 20.
Final answer: 20
2nd way:
You can do 1 minus 4/9 to find the left over fraction of the displays that the class needs to explore, which is equal to 5/9. Then, you need to find 5/9 of 36 to find how many displays are left for the class to explore. You can write it as 5/9 x 36, which is equal to 20.
Final answer: 20
Hope you understand and that this helps with your question :)

What is the probability that a randomly selected camper likes swimming or having a cookout, but not both?
A.
B.
C.
D
The probability that a randomly selected camper likes to have a cookout or swimming, but not both, is 0.10.
What is the probability?The Probability in mathematics is the possibility of an event in time. In simple words, how many times that incident is happening in any given time interval.
The Venn diagram displays the campers’ preferences.
One circle is labeled S, 0.06,
the other circle is labeled C, 0.04,
the shared area is labeled 0.89,
and the outside area is labeled 0.01.
The probability that a randomly selected camper likes to have a cookout or swimming, but not both,
= 0.06 + 0.04
= 0.10
Therefore, 0.10 is the required probability.

A store had 50 bottles of olive oil. Each week, 40% of the olive oil bottles were sold and 20 new bottles arrived in shipments. Which recursive function best represents the number of bottles in the store, given that f(0) = 50?
Answer:
f(n) = f(n-1)*.6 + 20
Step-by-step explanation:
f(0) = 50
f(n) = f(n-1)*.6 + 20
In fact, since f(0) = 50, f(n) = 50.

A researcher claims that the variation in the salaries of elementary school teachers is greater than the variation in the salaries of secondary school teachers (the claim). A random sample of 30 elementary school teachers has a variance of $ 8324, and a random sample of 30 secondary school teachers has a variance of $2862. At α= 0.05, can the researcher conclude that the variation in the elementary school teachers' Salaries is greater than the variation in the secondary teachers' salaries? Use the P-value method.
Assume that all variables are normally distributed.
a. State the hypotheses and identify the claim.
b. Find the critical value.
c. Compute the test value.
d. Make the decision.
e. Summarize the results.
Answer:
a
The null hypothesis is [tex]H_o : \sigma^2_1 = \sigma^2 _2[/tex]
The alternative hypothesis is [tex]H_a : \sigma_1 ^2 > \sigma^2_2[/tex]
b
[tex]F_{critical} = 1.8608[/tex]
c
[tex]F = 2.9085[/tex]
d
The decision rule is
Reject the null hypothesis
e
There is sufficient evidence to support the researchers claim
Step-by-step explanation:
From the question we are told that
The first sample size is [tex]n_1 = 30[/tex]
The sample variance for elementary school is [tex]s^2_1 = 8324[/tex]
The second sample size is [tex]n_2 = 30[/tex]
The sample variance for the secondary school is [tex]s^2_2 = 2862[/tex]
The significance level is [tex]\alpha = 0.05[/tex]
The null hypothesis is [tex]H_o : \sigma^2_1 = \sigma^2 _2[/tex]
The alternative hypothesis is [tex]H_a : \sigma_1 ^2 > \sigma^2_2[/tex]
Generally from the F statistics table the critical value of [tex]\alpha = 0.05[/tex] at first and second degree of freedom [tex]df_1 = n_1 - 1 = 30 - 1 = 29[/tex] and [tex]df_2 = n_2 - 1 = 30 - 1 = 29[/tex] is
[tex]F_{critical} = 1.8608[/tex]
Generally the test statistics is mathematically represented as
[tex]F = \frac{s_1^2 }{s_2^2}[/tex]
=> [tex]F = \frac{8324 }{2862}[/tex]
=> [tex]F = 2.9085[/tex]
Generally from the value obtained we see that [tex]F > F_{critical }[/tex] Hence
The decision rule is
Reject the null hypothesis
The conclusion is
There is sufficient evidence to support the researchers claim

The third and the sixth term of a geometric progression are 24 and 64/9 respectively. Find
a) the first term and common ratio
b) the sum of the first five terms
Answer:
Ai. Common ratio = 2/3
Aii. First term = 54
B. Sum of the first five terms = 422/3
Step-by-step explanation:
From the question given above, the following data were obtained:
3rd term (T3) = 24
6Th term (T6) = 64/9
First term (a) =?
Common ratio (r) =?
Sum of the first five terms (S5) =?
Ai. Determination of the common ratio (r).
T3 = ar²
T3 = 24
24 = ar²....... (1)
T6 = ar⁵
T6 = 64/9
64/9 = ar⁵......... (2)
The equation are:
24 = ar²....... (1)
64/9 = ar⁵......... (2)
Divide equation 2 by equation 1.
64/9 ÷ 24 = ar⁵ / ar²
64/9 × 1/24 = r³
8/27 = r³
Take the cube root of both side
r = 3√(8/27)
r = 2/3
Thus, the common ratio is 2/3
Aii. Determination of the first term (a).
T3 = ar²
3rd term (T3) = 24
Common ratio (r) = 2/3
First term (a) =?
24 = a(2/3)²
24 = 4a/9
Cross multiply
24 × 9 = 4a
216 = 4a
Divide both side by 4
a = 216/4
a = 54
Thus, the first term (a) is 54
B. Determination of the sum of the first five terms.
Common ratio (r) = 2/3
First term (a) = 54
Number of term (n) = 5
Sum of first five terms (S5) =?
Sn = a[1 –rⁿ] / 1 – r
S5 = 54[1 – (⅔)⁵] / 1 – ⅔
S5 = 54 [1 – 32/243] / ⅓
S5 = 54 (211/243) × 3
S5 = 54 × 211/81
S5 = 6 × 211/9
S5 = 2 × 211/3
S5 = 422/3
Thus, the sum of the first five terms is 422/3

PLEASE HELP ME WITH THIS ALGEBRA QUESTION!! THANK YOU!!
Answer:
The first four terms of the sequence are: {-10,-23,-62,-179}
Step-by-step explanation:
Given recursive formula is:
[tex]a_n = 3a_{n-1}+7[/tex]
First term = a1 = -10
The first term is already known. In order to find the next terms, we will put n=2,3,4 in the recursive formula.
Putting n=2
[tex]a_2 = 3a_{2-1}+7\\a_2 = 3a_1+7\\a_2 = 3(-10)+7\\a_2 = -30+7\\a_2 = -23[/tex]
Putting n=3
[tex]a_3 = 3a_{3-1}+7\\a_3 = 3a_2+7\\a_3 = 3(-23)+7\\a_3 = -69+7\\a_3 = -62[/tex]
Putting n=4
[tex]a_4 = 3a_{4-1}+7\\a_4 = 3a_3+7\\a_4 = 3(-62)+7\\a_4 = -186+7\\a_4 = -179[/tex]
Hence,
The first four terms of the sequence are: {-10,-23,-62,-179}

1/4 divided 3 please help me
Answer: 1/12
Step-by-step explanation:
how many 2/3 size pieces are in 4 wholes
Divide 4 wholes by 2/3 pieces to fnd number of pieces.
4 / 2/3
When you divide by a fraction, flip the fraction over then multiply:
4 x 3/2 = (4 x 3)/2 = 12/2 = 6
There are 6 pieces.
Answer:
6
Step-by-step explanation:
lets put this in terms of 3, because of 2/3. the number above the three will be divided by three to get to four. So if we multiply three by four to get twelve, we can put that over 3, and then find our answer. 12/3=4, so we know that is correct. and since we need to find how many 2/3 pieces we need, we divide 12/3 by 2/3 to get 6. so you need 6 2/3 pieces to get four wholes.
