The t-statistics that will ba calculated from the data about the steel housing will be -5.936.
How to calculate t-statistic?From the information given, the component part of the housing is a steel trough that is made out of a 14-gauge steel coil.
From the complete question that has the data, the t-statistic will be calculated thus:
u = 8.46
x bar = 8.422
s = 0.04
n = 49
Therefore, the t-statistics will be:
= (8.421 - 8.46) / (0.046 / ✓49)
= -5.936
In conclusion, the t-statistics is -5.936.

Find the mass of alcl3 that is produced when 10. 0 grams of al2o3 react with 10. 0 g of hcl according to the following equation. Al2o3(s) + 6hcl(aq) → 2alcl3(aq) + 3h2o(aq)
The balanced reaction
Al₂O₃ (s) + 6 HCl (aq) → 2 AlCl₃ (aq) + 3 H₂O (aq)
says that 1 mol Al₂O₃ reacts with 6 mol HCl to produce 2 mol AlCl₃.
We start with
• (10.0 g Al₂O₃) (1/101.96 mol/g) ≈ 0.0981 mol Al₂O₃
• (10.0 g HCl) (1/36.46 mol/g) ≈ 0.274 mol HCl
We can use up to
(0.274 mol HCl) (1 mol Al₂O₃ / 6 mol HCl) ≈ 0.0457 mol Al₂O₃
and consume all the HCl in the process (while also leaving an excess of about 0.0524 mol Al₂O₃) to produce approximately
2 (0.0457 mol Al₂O₃) (2 mol AlCl₃ / 1 mol Al₂O₃) ≈ 0.183 mol AlCl₃
This has a mass of about
(0.183 mol AlCl₃) (133.3 g/mol) ≈ 24.4 g AlCl₃

A doctor is measuring the mean systolic blood pressure of female students at a large college. Systolic blood pressure is known to have a skewed distribution. The doctor collects systolic blood pressure measurements from random sample of 28 female students. The resulting 90% confidence interval is (100. 4, 159. 6). Units of systolic blood pressure are mmhg. Which one of the following conclusions is valid?
Using the Central Limit Theorem, it is found that the valid conclusion is given as follows:
The sampling distribution will probably not follow a normal distribution, hence we cannot draw a conclusion.
Central Limit TheoremThe Central Limit Theorem establishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].
For a skewed variable, the sampling distribution is also approximately normal, as long as n is at least 30.
In this problem, we have a skewed variable with a sample size less than 30, hence the Central Limit Theorem cannot be applied and the correct conclusion is:
The sampling distribution will probably not follow a normal distribution, hence we cannot draw a conclusion.

A mixture of sodium hydroxide, naoh(s) and benzoic acid, hc7h5o2(s), consists of a total of 0. 50 moles. This mixture is dissolved in 1. 0 l of water and the ph of the resulting solution is determined to be 12. 52. Find the mole fraction of benzoic acid in the initial mixture
With a resulting solution of 12.52 and 1 m.l of water, the mole fraction of Benzoic acid that is in this mixture is 0.4669
How to solve for the mole fraction of Benzoic acidpH = 12.52
pOH = 14 - 12.52
= 1.48
OH⁻ = [tex]10^-^1^.^4^8[/tex]
= 0.0331
The concentration of excess ionsThe total number of excess OH⁻ that is required to make salt
= 0.5 - 0.0331
= 0.4669
H+ = 0.4669/2
= 0.2334
The mole fraction of Benzoic acid that would be here would be gotten by:

You are looking at comparable houses with the same asking prices in neighboring towns. The mill rate in the first town is 20 mills. The mill rate in the second town is 37 mills. Both houses are assessed at $175,000. Mill rate is the tax rate that is applied to the assessed value of a real estate property by a municipality. Your tax is calculated by multiplying the mill rate by the assessed value of a property and dividing by 1,000. What is the dollar difference in annual property taxes based on mill rate between the two towns?
The dollar difference in annual property taxes based on mill rate between the two towns is $2,975.
Dollar difference in annual property taxesFirst step is to calculate for first town
First town=Mill rate÷1,000×Property assessed value
First town=20 mills÷1000×$175,000
First town=$3,500
Second step is to calculate for second town
Second town=Mill rate÷1,000×Property assessed value
Second town=37mills÷1000×$175,000
Second town=$6,475
Third step is to calulate the difference
Difference=$6,475-$3,500
Difference=$2,975
Inconclusion the dollar difference in annual property taxes based on mill rate between the two towns is $2,975.

What right did women in the united states win by 1930? the right to work the right to vote the right to join the military the right to run for office
Answer: B! The right to vote!
Explanation:
just took test 100%
By 1930, women in the United States had won the right to work, which meant they were legally permitted to work outside the home.
What is right to work?The term "right-to-work laws" refers to state laws in the United States that prohibit union security agreements between employers and labor unions that require employees.
By 1930, women in the United States had won the right to work, which meant they were legally permitted to work outside the home.
The right to vote, however, had already been secured with the ratification of the 19th Amendment to the United States Constitution in 1920.
Women were also allowed to join the military in 1948 and to run for office in 1916, though it took many more years for women to break down gender barriers in politics and achieve high-level political leadership roles.
Thus, the answer is right to work.

A 20 kg box rests on a table. What force does the earth exert on the box?
Answer:
The normal force acting on the body is equal to its weight, hence;
N = W = 196N
The normal force that the 20.0-kg box exerts on the 10.0-kg box is 98N
The formula for calculating the weight of an object is expressed as:
W = mg
m is the mass of the object
g is the acceleration due to gravity.
Given the following parameters
Mass of the box = 20.0kg
a) The weight of the box = 20 * 9.8
Weight of the box = 196N
Hence the weight of the box is 196N
Note that the normal force acting on the body is equal to its weight, hence;
N = W = 196N
b) if a 10.0-kg box is placed on top of the 20.0-kg box, the total mass will be;
M = 10 + 20 = 30kg
total weight = 30 * 9.8
Total weight = 294N
Since the normal force is equal to the weight, hence W = N = 294N
Weight of the 10kg box = 10 * 9.8 = 98N
Since the 10kg box is on top of the 20kg box, hence the normal force that the 20.0-kg box exerts on the 10.0-kg box is 98N
