Find the total surface area and volum of given prism
Answer:
Total surface area = 434 cm²
Total volume = 470 cm³
Step-by-step explanation:
1. The prism can be decomposed into two rectangular prisms which are the bigger rectangular prism and the smaller rectangular prism
✔️Total surface area of the prism = (surface area of the bigger prism - area of the face joined to the smaller prism) + (surface area of the smaller prism - area of the face joined to the bigger prism)
Surface Area of bigger prism = 2(LW + LH + HW)
L = 10 cm
H = 8 cm
W = 9 - 5 = 4 cm
Area of bigger rectangular prism = 2(10*4 + 10*8 + 8*4)
= 304 cm²
Surface area of the smaller prism = 2(LW + LH + HW)
L = 10 cm
H = 3 cm
W = 5 cm
Area of bigger rectangular prism = 2(10*5 + 10*3 + 3*5)
= 190 cm²
Area of the face joining both rectangular prisms = L*W
L = 10 cm
W = 3 cm
Area = 10*3 = 30 cm²
✅total surface area of the prism = (304 - 30) + (190 - 30) = 274 + 160 = 434 cm²
2. Volume of the prism = volume of the bigger rectangular prism + volume of the smaller rectangular prism
✔️Volume of the bigger rectangular prism = L*W*H
L = 10 cm
H = 8 cm
W = 9 - 5 = 4 cm
Volume = 10*8*4 = 320 cm³
✔️✔️Volume of the bigger rectangular prism = L*W*H
L = 10 cm
H = 3 cm
W = 5 cm
Volume = 10*3*5 = 150 cm³
✅Total Volume of the prism = 320 + 150 = 470 cm³

Answer:
3
Step-by-step explanation:
So, the little arow underneath lim that says x>1, this means that the qiuestion is asking:
What is the limit when x gets to 1?
We can use the quadratic they give us to solve this. Now, if you are doing this, you should know how to make a quadratic equation. So instead of making this long and tedious for you, I will use a graphing calculator.
So lets look at the graph below, specificly where x=1
as x reaches 1, what does the y coordinates look to be about? 3.
So we can conclude that the answer is that when x→1, y=3

Determine the decision criterion for rejecting the null hypothesis in the given hypothesis test; i.e., describe the values of the test statistic that would result in rejection of the null hypothesis. We wish to compare the means of two populations using paired observations. Suppose that d3.125, 2.911, and n8, and that you wish to test the hypothesis below at the 10% level of significance. What decision rule would you use? : 0 against : 0
Answer:
Decision Rule
The critical region for one tailed test with 7 d.f is t > 1.415 for
H0 : ud ≤ 0 against the claim Ha: ud > 0
Step-by-step explanation:
The data given is
Population mean = ud= 0
Sample difference mean = d`= 3.125
Sample difference standard deviation = sd= 2.911
Sample size= n= 8
Formulate the null and alternate hypotheses as
H0 : ud ≤ 0 against the claim Ha: ud>0
The significance level ∝= 0.1
The degrees of freedom = n-1 = 8-1 = 7
The critical region for one tailed test with 7 d.f is t > 1.415
The test statistic is
t= d`- ud/ sd/ √n
Putting the values
t= 3.125-0 / 2.911/√8
t= 3.125/1.0292
t= 3.036
since the calculated value of t falls in the critical region we reject the null hypothesis .

Answer:
R ≈ 7.4
Step-by-step explanation:
Substitute I = 25000000 into the equation
log(25000000 ) = R , then
R ≈ 7.4 ( to 1 dec. place )
Answer:
The Richter scale measurements of an earthquake with intensity 25,000,000 is R ≈ 7.4
Step-by-step explanation:
using the given formula R = log ISubstitute I = 25000000 into the equation
R= log(25000000 ) , then by using calculator we get
R =7.3979
R≈7.4

Keisha, Boris, and Jose sent a total of 126 text messages over their cell phones during the weekend. Boris sent 4 times as many messages as Jose. Jose sent 6 fewer messages than Keisha. How many messages did they each send?
Answer:
Boris=504 keisha=120
Step-by-step explanation:
First you would start off by Multiplying 4x126 the result of that is= 504 so thats how much Boris sent. To get the answer to how many jose sent you simply just subtract 6-126 and that should result in 120

system of equations show below?
Y+ 2x = 5
4y+ 5x=14
A. x=2 y=1
B. x= 1, y = 2
O C. More than 1 solution
O D. No solution
Answer:
x = 2 y = 1
Step-by-step explanation:
Given the system of equation
Y+ 2x = 5 ...1
4y+ 5x=14 ,,,,2
From 1;
y =5 - 2x ....3
Substitute 3 into 2
4(5-2x) + 5x = 14
20 - 8x + 5x = 14
20 - 3x = 14
-3x = 14-20
-3x = -6
x = 6/3
x = 2
Since y = 5-2x
y = 5-2(2)
y = 5-4
y = 1
Hence the required solution is (2,1)

What is the 31st term in the sequence 204,200,196
Answer:
a(31) = 84
Step-by-step explanation:
The first term, a(1) is 204, and the common difference is 4. That is, each new term is 4 less than the previous term.
The rule governing this arithmetic sequence is
a(n) = 204 - 4(n - 1)
and so the 31st term is
a(31) = 204 - 4(30) = 84

A car company hires a marketing firm to advertise a particular model of car. After a year the marketing company presents the following graph to show the increase in sales resulting from their advertising campaign.
Answer:
Yes, the graph makes it appear as if sales increased three folds.
Step-by-step explanation:
The graph presented by the advertising company is misleading, as it attempts to exaggerate the effect of its advert on sales. This can be attributed to the scale which is isn't uniform.
Last year sale was about 137000 and it grew to 150000 as a result of advertisement.
But from the bar chart, it seems there was three times increase in sales.
A survey of 300 students from a New York State School District reveals that 112 favor year round school with two week vacations every ten weeks. Construct the 98% confidence interval for the true population proportion of all New York students who favor year round school.
Answer:
The 98% confidence interval for the true population proportion of all New York students who favor year round school is (0.3083, 0.4383).
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of [tex]\pi[/tex], and a confidence level of [tex]1-\alpha[/tex], we have the following confidence interval of proportions.
[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
In which
z is the z-score that has a p-value of [tex]1 - \frac{\alpha}{2}[/tex].
A survey of 300 students from a New York State School District reveals that 112 favor year round school with two week vacations every ten weeks.
This means that [tex]n = 300, \pi = \frac{112}{300} = 0.3733[/tex]
98% confidence level
So [tex]\alpha = 0.02[/tex], z is the value of Z that has a p-value of [tex]1 - \frac{0.02}{2} = 0.99[/tex], so [tex]Z = 2.327[/tex].
The lower limit of this interval is:
[tex]\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.3733 - 2.327\sqrt{\frac{0.3733*0.6267}{300}} = 0.3083[/tex]
The upper limit of this interval is:
[tex]\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.3733 + 2.327\sqrt{\frac{0.3733*0.6267}{300}} = 0.4383[/tex]
The 98% confidence interval for the true population proportion of all New York students who favor year round school is (0.3083, 0.4383).

The function y = 45x + 300 can be used to model the cost of buying new furniture and making monthly payments over a period of x months. Which of the following best describes the y-intercept of the graph?
Group of answer choices-
the monthly payment amount
the amount of the down payment
the number of pieces of furniture bought
the number of months to pay off the balance
Answer:
The Answer is B
Step-by-step explanation:
If we are looking at money we are looking at the total amount u need to pay and if u are paying 45 a month times whatever x is. 300 would stand for the amount already paid or the down payment made.
Option B is correct, the best description of the y-intercept of the graph is the amount of the down payment.
What is slope intercept form of line?The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.
In the given function, y = 45x + 300
x represents the number of months and y represents the total cost of buying new furniture and making monthly payments over that period.
The term 300 is the y-intercept of the graph, which means it is the value of y when x is zero.
Since x represents the number of months, which is zero at the time of purchase, the y-intercept of the graph represents the cost of buying new furniture without making any monthly payments.
Therefore, the best description of the y-intercept of the graph is the amount of the down payment. Option B is correct.
