A cement mixer can hold up to 681 kilograms of cement. How many 100-pound bags of cement can be put into the mixer at one time?
Answer:
15 bags
Step-by-step explanation:
Given that :
Capacity of mixer = 681 kg
Pounds per bag of cement = 100 pounds
Number of bags mixer can hold =?
Converting the capacity of mixer to pounds :
1kg = 2.205 pounds
681 kg = (681 * 2.205) pounds = 1501.605 pounds
Number of 100 pound bag of cement :
Capacity in pounds / 100 pounds
1501.605 / 100
= 15.016
= 15 bags of 100 pound cement

Suppose that shoe sizes of American women have a bell-shaped distribution with a mean of 8.15 and a standard deviation of 1.52. Using the empirical rule, what percentage of American women have shoe sizes that are less than 11.19
Answer:
97.5% of American women have shoe sized less than 11.19
Step-by-step explanation:
Here, we want to use the empirical rule to find the percentage of women with shoe sizes less than 11.19
The first thing we shall do here is to find the z-score
Mathematically, that will be calculated using the formula;
z = (x-mean)/SD
z = (11.19-8.15)/1.52
z = 2
We can see that the given value is 2 standard deviation away to the right of mean
So, we want to get the percentage that is between the mean and two standard deviations away from it using the empirical rule
So according to the empirical rule
The percentage will be
100-2.35-0.15
= 100-2.5 = 97.5%

A farmer owns 24 acres of land. He plans to use 6 acres for an entrance into the farm and divide the remaining land into 1/3 acre lots. How many 1/3 acre lots will he have?
Answer:
54 one-third acre lots
Step-by-step explanation:
24 - 6 = 18
18 ÷ 1/3 = 18 × 3 = 54
Answer: 54
Step-by-step explanation:The remaining portion to be divided into 1/3 acre lots is the difference between the number of acres owned by the farmer and the number of arces used for the entrance. This difference is
= 24 arces - 6 arces
= 18 acres
These acres is to be divided into 1/3 arce then the number of 1/3 arce loits that will be available
= 18 ÷ 1/3
= 18 × 3/1
= 54
There are 120 students at Francis Howell North High School. Mr. Willott conducts a poll that asks 20 randomly selected students how many hours of sleep they got last night. They find that the mean amount of sleep is 6.7 hours. The population standard deviation is σ = 2 hours. Can we estimate the standard deviation of the sampling distribution of means by using σ divided by the square root of n (2/sqrt(20) = 0.557 hours)?
Answer:
Yes
Step-by-step explanation:
The central limit theorem says that If a random variable X from a population has mean u and finite variance σ² , then the sampling distribution of the sample mean X~ approaches a normal distribution with mean u and variance σ²/n as the sample size n approaches infinity.
It is interesting to note that we have neither assumed that the distribution of X is continuous nor we have said anything about the shape of the distribution , whereas the limiting distribution of X is continuous and normal. Thus the distribution of the sample means regardless of the shape of the population having a finite variance , is approximately normal with mean u and variance σ²/n .
Therefore
(standard deviation/ √sample size)²= variance / n
2/ √20
= 2/4.472
=0.44721
The sampling distribution of X` is therefore approximately normal with mean ux=u and σx =σ/n
Yes, we estimate the standard deviation of the sampling distribution of means by using σ divided by the square root of n and this can be determined by finding the mean and standard deviation for the distribution of the sample means.

help i can't figure this out it's algebra
Step-by-step explanation:
Part A:
The maximum point is (2.5, 2531.25). This represents that $2.5 should be decreased from the original price to achieve the most profit from t-shirt sales.
Part B:
The y-intercept is seen to be around (0, 2500). This tells us that the profit made from the original price is $2500.
Part C:
Yes. The point (25, 0) is a solution. It tells us that if we decreased the original price by $25, we would make no/zero profit.
Answer:
Step-by-step explanation:
A. The optimal decrease in price to gain the maximum profit in sale:
Meaning if you reduce the price by $2.5, you will gain the maximum profit of $2531.25
B. It represents the amount of profit without any change in the current price on the t-shirt.
By shifting and expanding the original equation [tex]y=-x^{2}\\[/tex]
[tex]y = -5(x-2.5)^{2} + 2531.25[/tex]
[tex]x = 0 => y = 2500[/tex]
C. The solution is as in part B
It represents by reducing the price of each t-shirt, there is an initial increase in profit but eventually it will drop.

Step-by-step explanation:
According to Pythagoras Theorem
(Hypotenuse)² = (Base)² + ( Perpendicular)²
We need to find Base so arranging the equation will give us
(Base)² = (Hypotenuse)² - ( Perpendicular)²
Taking under root on both sides
Base = √(Hypotenuse)² - ( Perpendicular)²
Base = √ (625 - 100)
Base = √525
Base = 23 feet

The correct answer is X=5
I'm 10000000000% sure
Answer:
x = 5
Step-by-step explanation:
First, to get rid of the fraction, multiply both sides of the equation by x.
— (14.8/x + 2.4) * x = 5.36 * x
— 14.8 + 2.4x = 5.36x
Next, subtract 2.4x from both sides of the equation.
— 14.8 + 2.4x - 2.4x = 5.36x - 2.4x
— 14.8 = 2.96x
Now, divide both sides of the equation by 2.96.
— 14.8/2.96 = 2.96x/2.96
— 5 = x
The waiting time for a bus has a uniform distribution between 2 and 13 minutes. What is the probability that the waiting time for this bus is less than 4.5 minutes on a given day
Answer: 0.2273
Step-by-step explanation:
Probability density function for uniform distribution is given by :-
[tex]f(x)=\dfrac{1}{b-a}[/tex], where x is uniformly distributed in [a,b].
Let x denotes the waiting time for this bus.
Given : The waiting time for a bus has a uniform distribution between 2 and 13 minutes.
Probability distribution function of x for interval [2,13] will be :-
[tex]f(x)=\dfrac1{13-2}=\dfrac{1}{11}[/tex]
Required probability : P(x<4.5) = [tex]\int^{4.5}_{2}f(x)\ dx[/tex]
[tex]=\int^{4.5}_{2}\dfrac1{11}\ dx\\\\=\dfrac1{11}[x]^{4.5}_{2}\\\\ = \dfrac1{11}(4.5-2)\\\\=\dfrac1{11}(2.5)\approx0.2273[/tex]
Hence, the probability that the waiting time for this bus is less than 4.5 minutes on a given day = 0.2273
