the height of a house having three rooms of the dimensional 9 feet into 12 feet 14 feet into 16 feet and 12 feet into 14 feet respectively is 90 Feet what will be the amount required to paint on all was from inside at the rate of 160 per square feet
Answer:
Amount required = 2,217,600
Step-by-step explanation:
Dimensions of the rooms are as follows;
Room 1; 9 feet × 12 feet
Room 2; 14 ft × 16 ft
Room 3; 12 ft × 14 ft
Perimeter of rooms;
P1 = 2(9 + 12) = 42 ft
P2 = 2(14 + 16) = 60 ft
P3 = 2(12 + 14) = 52 ft
Total perimeter; P = 42 + 60 + 52 = 154 ft
Height is 90 ft.
Thus, total area is;
A = 154 × 90
A = 13860 ft²
Rate of painting is 160 per Sq.ft.
Thus amount to paint entire area = 160 × 13860 = 2217600

Answer:
8
Step-by-step explanation:
So, the small red circles are the baskets.
Each 1 represents 1 basket.
We know that the two baskets on 4 wont be counted, as well as the two baskets on 4 1/2, since thats smaller than or equal to 4 1/2
We also know that the two baskets on 6 wont be counted either, since thats equal to 6.
So now lets count the baskets in between these values, which would be:
5 - 4 baskets
5 1/2 - 4 baskets
Lets add those up:
4+4
=
8

One number is five more than three times a second number. The sum of the numbers is 37. What are the numbers?
Answer:
11
Step-by-step explanation:
Answer:
29, 8
Step-by-step explanation:
1. let x = 1st number and y = 2nd number.
2. The 1st sentence translates into: x = 3y+5
3. 2nd sentence translates into: x + y = 37.
4. x+y = 37 --> y = 37-x
5. x = 3(37-x)+5
x = 111-3x +5
4x = 116
x = 29
y = 37-x = 37-29 = 8
6. x = 29, y = 8

A class consists of 23 women and 83 mean. If a student is random selected, what is the probability that the student is a woman?
Answer:
[tex]P(Woman) = \frac{23}{106}[/tex]
Step-by-step explanation:
Given
[tex]Women = 23[/tex]
[tex]Men = 83[/tex]
Required
[tex]P(Woman)[/tex]
This is calculated as the number of women divided by the population of the class
i.e.
[tex]P(Woman) = \frac{Women}{Women + Men}[/tex]
So, we have:
[tex]P(Woman) = \frac{23}{23+83}[/tex]
[tex]P(Woman) = \frac{23}{106}[/tex]

It has been claimed that, for a penny minted in 1999 or earlier, the probability of observing heads upon spinning the penny is p = 0.3. Three students got together, and they would each spin a penny and record the number X of heads out of the three spins. They repeated this experiment 200 times, observing 0, 1, 2, and 3 heads 57, 95, 38, and 10 times, respectively. Use these data to test the hypotheses that X is b(3, 0.3) that is binomial with n = 3 and p = 0.3 using
Answer:
accept Null hypothesis at ∝ = 0.05

You are given the results of measurement of resistors. We are testing the
measurement tool. It will pass the technical control if the mean value will be
in the range [198-202] with standard deviation less than 3 Ohms. Will the tool
pass the technical control?
Answer:
As both the mean and standard deviation are in the desired ranges, the tool passes the technical control.
Step-by-step explanation:
Mean of the batch:
The mean of the batch is the sum of all values divided by the number of items. So
[tex]M = \frac{199+204+201+197+195+204+200}{7} = 200[/tex]
Mean in the desired interval.
Standard deviation:
Square root of the sum of the difference squared between each term and the mean, divided by the number of items. So
[tex]S = \sqrt{\frac{(199-200)^2+(204-200)^2+(201-200)^2+(197-200)^2+(195-200)^2+(204-200)^2+(200-200)^2}{7}} = 1.18[/tex]
As both the mean and standard deviation are in the desired ranges, the tool passes the technical control.
2. Solve 92n = 404n-7. Round to the nearest ten-thousandth, which is four places after the decimal
point.
Answer:
n = 0.0224
Step-by-step explanation:
The given expression is :
92n = 404n-7
We need to solve it for n.
Subtract 92n from both sides,
92n-92n = 404n-7-92n
7 = 404n-92n
7 = 312 n
n = 0.0224
So, the value of n is equal to 0.0224.

you're having a bbq this weekend, and you're in charge of hamburger meat. right now there is a sale where you can buy 5 pounds of meat for $10. At this rate how much meat could you buy for $30
Answer:
15 pounds
Step-by-step explanation:
we can set up a proportion:
5/10=x/30
solve for x:
5/10=x/30
10x=150
x=15
(or you could've done 5*3=15 since $30/$10=3)

The mean area of homes in a certain city built in 2009 was 2438 square feet. Assume that a simple random sample of 11 homes in the same city built in 2010 had a mean area of 2,293 square feet, with a standard deviation of 225 square feet. An insurance company wants to know if the mean area of homes built in 2010 is less than that of homes built in 2009. Compute the P-value of the test. Write down your P-value. You will need it for the next question.
Answer:
The p-value of the test is 0.029.
Step-by-step explanation:
The mean area of homes in a certain city built in 2009 was 2438 square feet.
An insurance company wants to know if the mean area of homes built in 2010 is less than that of homes built in 2009.
This means that at the null hypothesis we test if the mean is the same as in 2009, that is:
[tex]H_0: \mu = 2438[/tex]
At the alternate hypothesis, we test that if it is less, than is;
[tex]H_a: \mu < 2438[/tex]
The test statistic is:
[tex]t = \frac{X - \mu}{\frac{s}{\sqrt{n}}}[/tex]
In which X is the sample mean, [tex]\mu[/tex] is the value tested at the null hypothesis, s is the standard deviation and n is the size of the sample.
2438 is tested at the null hypothesis:
This means that [tex]\mu = 2438[/tex]
Assume that a simple random sample of 11 homes in the same city built in 2010 had a mean area of 2,293 square feet, with a standard deviation of 225 square feet.
This means that [tex]n = 11, X = 2293, s = 225[/tex]
Value of the test statistic:
[tex]t = \frac{X - \mu}{\frac{s}{\sqrt{n}}}[/tex]
[tex]t = \frac{2293 - 2438}{\frac{225}{\sqrt{11}}}[/tex]
[tex]t = -2.14[/tex]
Compute the P-value of the test.
Probability of finding a mean less than a value(in this case, 2293) is a one-tailed test.
The pvalue is found for a one-tailed test, with t = -2.14 and 11 - 1 = 10 degrees of freedom. With the help of a calculator, the pvalue of the test is of 0.029
The p-value of the test is 0.029.

Answer:
[tex]\boxed {\boxed {\sf x=28}}[/tex]
Step-by-step explanation:
This is a right triangle. The small square in the corner represents a 90 degree angle. We can use trigonometry. The three major ratios are:
sin(θ)=opposite/hypotenuse cos(θ)=adjacent/hypotenuse tan(θ)= opposite/adjacentThe angle, or θ, is 60 degrees. The side measuring 14 is adjacent to this angle. x is the hypotenuse because it is opposite the right angle. Since we have the adjacent side and the hypotenuse, we use cosine.
[tex]cos (\theta) = \frac {adjacent}{hypotenuse}[/tex]
[tex]cos(60)= \frac{14}{x}[/tex]
Since we are solving x, we must isolate the variable. First, cross multiply.
[tex]\frac {cos(60)}{1}= \frac{14}{x}[/tex]
Multiply the first numerator (cos60) by the second denominator (x).
Then, multiply the first denominator (1) by the second numerator (14)
[tex]cos (60)*x= 14*1[/tex]
[tex]cos(60)*x= 14[/tex]
The cosine of 60 is equal to 1/2,
[tex]\frac{1}{2} x= 14[/tex]
x is being multiplied by 1/2. The inverse of multiplication is division. Divide both sides of the equation by 1/2. Since this is a fraction, you can also multiply by the reciprocal: 2.
[tex]2* \frac{1}{2} x= 14 *2[/tex]
[tex]x=14 *2\\ x=28[/tex]
The hypotenuse, x, is equal to 28.
