In 1 month it rained 12 inches. Then it rained 3 inches per month for 9 months. How many inches did it rain in all?
Answers
Answer: 39
Step-by-step explanation: Just addition
Answer:
Total rainfall = 39 inches.
Step-by-step explanation:
The question is not properly qualified. I am assuming that the first month, 12 inches of rain fell (that is an awful lot) and for the next 9 months the rainfall was 3 inches per month.
Let R be the total rainfall.
R = first month + 9*3
R = 12 + 27
R = 39

the ratio of the age of father and his son is 9:4. if the son is 24 years old find the age of father
Answers
Answer:
The father is 54 years old
Step-by-step explanation:
Well from the ratio 9:4
We know the son is 24
we can divide 24/4 to get 6
now we know we have to multiply by 6 on each side of the ratio to get the final result
54:24
Answer:
54 years old
Step-by-step explanation:
Because the son is 24 years old, we know that that is 6 times the '4' in the ratio 9:4 therefore if we do 6*9=54 that is the age of his father!

A construction crew is lengthening a road that originally measured 44 miles. The crew is adding 1 mile to the road each day. The length, L (in miles), after d days of construction is given by the following function.
L(d)= 44+d
What is the length of the road after 35 days?
Answers
Answer:
The length of the road after 35 days is of 79 miles.
Step-by-step explanation:
The length of the road, after d days, is given by:
[tex]L(d) = 44 + d[/tex]
What is the length of the road after 35 days?
This is l when d = 35. So
[tex]L(35) = 44 + 35 = 79[/tex]
The length of the road after 35 days is of 79 miles.
A manufacturer of banana chips would like to know whether its bag filling machine works correctly at the 421 gram setting. It is believed that the machine is underfilling the bags. A 26 bag sample had a mean of 413 grams with a standard deviation of 24. Assume the population is normally distributed. A level of significance of 0.02 will be used. Find the P-value of the test statistic. You may write the P-value as a range using interval notation, or as a decimal value rounded to four decimal places.
Answers
Answer:
The p-value is approximately 0.0508
Step-by-step explanation:
The given parameters are;
The expected mass of banana chips bag filled by the machine, μ = 421 gams
The number of bags in the sample of bags filled by the machine, n = 26 bags
The mean mass of the bags in the sample, [tex]\overline x[/tex] = 413 grams
The standard deviation of the mass in the bags, s = 24 grams
The level of significance, α = 0.02
The null hypothesis, H₀; μ = 421 grams
The alternative hypothesis, Hₐ; μ < 421 grams
The test statistic is given as follows;
[tex]t=\dfrac{\bar{x}-\mu }{\dfrac{s}{\sqrt{n}}}[/tex]
We get;
[tex]t=\dfrac{413-421 }{\dfrac{24}{\sqrt{26}}} \approx -1.6996731712[/tex]
The t-value = -1.6996731712
The degrees of freedom df = n - 1 = 26 - 1 = 25
From an online source, we get the critical-t = 2.166587
The p-value is obtained using an online source as p(t ≤ -1.6996731712) = 0.0508
From the p-value table, we get
0.05 < p < 0.1
A store gives customers a markup of 13%. If the store sells a belt for $25, what was the wholesale price paid for the belt by the store?
Answers
Answer:
$22.12
Step-by-step explanation:
Let x be the wholesale price (the price before adding the markup).
The markup is 13%, so 13% of x is added to x.
x + 13%x = $25
x + 0.13x = 25
1.13x = 25
x = 25/1.13
x = 22.12

Step-by-step explanation:
The coordinate of A is (2,-4) currently. If we reflect that point over the x-axis, the y coordinate will change into the opposite sign. Because the y coordinate is -4, it will change to - (-4) = 4. Therefore, the coordinate of A' would be (2,4).

Step-by-step explanation:
I'm assuming this is asking for 3 separate fractions that are each equal to 2/3
Remember, multiplying the top and bottom of a fraction by a number will not change the fraction.
[tex]\frac{2}{3} *\frac{2}{2} =\frac{4}{6}[/tex]
[tex]\frac{2}{3} *\frac{3}{3} =\frac{6}{9}[/tex]

Melanie is going to invest $45,000 and leave it in an account for 20 years. Assuming
the interest is compounded continuously, what interest rate, to the nearest
hundredth of a percent, would be required in order for Melanie to end up with
$142,000?
Answers
Answer:
Rate of interest r = 5.20% (Approx.)
Step-by-step explanation:
Given:
Amount invested p = $45,000
Final amount A = $142,000
Number of year = 20
Find:
Rate of interest r
Computation:
A = p[1+r]ⁿ
142,000 = 45,000[1+r]²⁰
3.1556 = [1+r]²⁰
r = 5.194

A cell phone provider classifies its customers as Low users (less than 400 minutesper month) or High users (400 or more minutes per month). Studies have shownthat 80% of the people who were Low users one month will be Low users the nextmonth, and that 70% of the people who were High users one month will be Highusers the next month.
(a) Set up the 2x2 stochastic matrix with columns and rows labeled L and H that displays these transitions
(b) Suppose that, during the month of January, 50% of the customers were Low users. What percent of the customers will be Low users in February? In March? (Type an integer or decimal for each matrix element.)
Answers
1. The stochastic matrix for the given transitions is:
[tex]T = \left[\begin{array}{ccc}0.80 & 0.20\\0.30&0.70 \end{array}\right]\\[/tex]
2. 40.0% people in February and 32.0% people in March will be the low users if there are 50% low users in January.
It is given that,
80% of the people who were Low users one month will be Low users the next month.
That means for the transition low-low (L-L)
p = 0.80
So, for Low-high transition (L-H)
p = 1-0.80 = 0.20
It is also given that 70% of the people who were High users one month will be High users the next month.
That means, p = 0.70 for the transition high-high (H-H)
Then for H-L transition, p = 1-0.70 = 0.30
(a) The 2x2 stochastic matrix for these transitions is:
[tex]T = \left[\begin{array}{ccc}0.80 & 0.20\\0.30&0.70 \end{array}\right]\\[/tex]
(b) Given that 50% users are the low users in month of January.
[tex]\text{Percent of the customers will be Low users in February}= (\text{low users in month of January} \times \text{Probability of L-L transition.}) \times 100\%[/tex]= (0.50 x 0.80)x100%
= 0.4x 100%
=40.0%
Now, the percentage of people who will be low users in the month of march = (low users in February x probability of L-L transition)x100%
=(0.40x0.80)x100%
=0.32x100%
=32.0%
Hence, the percentage of people who will be low users in the month of February and in the month of March are 40.0% and 32.0% respectively.
Therefore, the results are:
1.2x2 stochastic matrix for the transitions is as:
[tex]T = \left[\begin{array}{ccc}0.80 & 0.20\\0.30&0.70 \end{array}\right]\\[/tex]
2. The percentage of people who will be low users in the month of February and in the month of March are 40.0% and 32.0% respectively.
