Keeping car tires inflated is essential to safe driving. For one type of car tire, the tire pressure in pounds per square inch (psi) is assumed to be approximately Normal, with a mean of 35 psi and a standard deviation of 2 psi. What percentage of tires are inflated to a pressure between 33.5 and 36 psi?
Find the z-table here.
22.55%
46.48%
53.52%
77.45%
Answer:
Step-by-step explanation:
The text is a statistics problem that asks to find the probability of a certain range of values in a normal distribution. A normal distribution is a bell-shaped curve that shows how data values are spread around the mean. The mean is the average of all the data values, and the standard deviation is a measure of how much the data values vary from the mean. To solve this problem, we can use the following steps:
Convert the given range of values to standard scores or z-scores. A z-score tells us how many standard deviations a value is away from the mean. To find the z-score, we use the formula: z=σx−μ
where x is the value, μ is the mean, and σ is the standard deviation. For example, to find the z-score for 33.5 psi, we plug in the values: z=233.5−35=−0.75
This means that 33.5 psi is 0.75 standard deviations below the mean. Similarly, to find the z-score for 36 psi, we plug in the values: z=236−35=0.5
This means that 36 psi is 0.5 standard deviations above the mean.
Use a z-table to find the area under the curve for each z-score. A z-table is a table that shows the probability of getting a z-score less than or equal to a given value. For example, to find the area under the curve for -0.75, we look up the row for -0.7 and the column for 0.05 in the z-table and get 0.2266. This means that there is a 22.66% chance of getting a z-score less than or equal to -0.75. Similarly, to find the area under the curve for 0.5, we look up the row for 0.5 and the column for 0 in the z-table and get 0.6915. This means that there is a 69.15% chance of getting a z-score less than or equal to 0.5.
Subtract the smaller area from the larger area to find the area between the two z-scores. This area represents the probability of getting a value between 33.5 and 36 psi in the normal distribution. For example, to find the area between -0.75 and 0.5, we subtract: 0.6915−0.2266=0.4649
This means that there is a 46.49% chance of getting a value between 33.5 and 36 psi in the normal distribution.
Multiply the area by 100 to convert it to a percentage and write it with the appropriate units: The percentage of tires that are inflated to a pressure between 33.5 and 36 psi is 0.4649×100=46.49%

Answer: 207^2 + 9km^2 = 216km^2
Step-by-step explanation:
(my explanation is wrong)
All you want to do is break this figure up into rectangles and triangles.
I see 3 rectangles and 1 triangle.
Three Rectangles:
The bottom one has the dimension of 5 and 20. 5 x 20 = 100 km^2
The middle one has the dimensions of 5+4 and 7. 9 x 7 = 63 km^2
The top one has the dimensions of 4 and 11. 4 x 11 = 44 km^2
Add them all up to get 207km^2
One Triangle:
We can see at the bottom rectangle that the left side is 5 and the right side is 3 + x. X being our missing height of the triangle. The height equals 2.
The triangle now has the dimensions of 2 and 6. 2 x 6 = 12. Then divide by 2 to get 6 km^2
Answer:
216 km²
Step-by-step explanation:
To solve this, you have to divide the figure into different parts. I divided the parts up into four sections. I will work on the parts in numerical order.
1. At the top of the rectangle, it is marked 4 km. On the left side, it is marked 11 km. This is the length and width.
A = lw
A = 11 × 4
A = 44 km²
2. On the left side of this rectangle, it is marked 7 km. At the top it is marked 5 km, but there is a portion that does not have a measurement (the part with a different color than the rest. Because this line is also part of rectangle 1, we know that the line is 4 km. Adding up the two numbers gives you 9 km.
4 + 5 = 9
A = lw
A = 7 × 9
A = 63 km²
3. On the left side, it is marked 5 km. On the bottom, it is marked 20 km.
A = lw
A = 20 × 5
A = 100 km²
4. This is one is a bit more tricky. This is a triangle, so we have to find the base and the height. The base is 6 km. You have to figure the height. Look at the picture with the red lines.
The red line on the right side has a length of 17 + 3 + x = 20 + x. The length is 20 + x because there is a portion of the line that is missing.
The red lines on the left side have a length of 5 + 7 + 11 = 23. The two side should be equal so
23 = 20 + x
x = 3
Now, you have the height. Use the equation for area of a triangle to solve.
A = 1/2bh
A = 1/2(3)(6)
A = 1/2(18)
A = 9 km²
Now you have to add up all the areas to find the total area.
44 km² + 63 km² + 100 km² + 9 km² = 216 km²
What is the value of the expression 9 + (1/2) with a power of 4 • 48? A. 12 B. 15 C. 17 D. 18
Answer:
Option A
Step-by-step explanation:
Given the following question:
\(9+(\frac{1}{2})^4\times48\)
In order to find this, answer we use order of operations and solve.
\(9+(\frac{1}{2})^4\times48\)
\(\frac{1}{2} ^4=\frac{1}{2} \times\frac{1}{2} \times\frac{1}{2} \times\frac{1}{2} =\frac{1}{16}\)
\(9+\frac{1}{16} \times48\)
\(\frac{1}{16} \times48=\frac{1}{16}\times\frac{48}{1} =\frac{3}{1} =3\)
\(9+3\)
\(9+3=12\)
\(=12\)
Which means your answer is option A or "12."

Help please!!! What was the number of small, medium, and large pizzas delivered to the college?
In the word problem above, 0 small pizzas, 1 medium pizza, and 5 large pizzas were delivered to the college.
How is this so?Let S = number of small pizzas delivered
Let M = number of medium pizzas delivered
Let L = number of large pizzas delivered
We'll start by solving equation 1 for one variable and substituting it into the other equations.
S + M + L = 12
We can rewrite this equation as -
S = 12 - M - L
Now, substitute this value of S in equations 2 and 3 -
4S + 10M + 15L = 109
4(12 - M - L) + 10M + 15L = 109
48 - 4M - 4L + 10M + 15L = 109
6M + 11L = 61
2S + 4M + 13L = 81
2(12 - M - L) + 4M + 13L = 81
24 - 2M - 2L + 4M + 13L = 81
2M + 11L = 57
Now we have a system of two equations with two variables -
6M + 11L = 61 ...(4)
2M + 11L = 57 ...(5)
Subtract equation (5)from equation (4) -
(6M + 11L) - (2M +11L) = 61 - 57
4M = 4
M = 1
Substitute the value of M into equation (5) -
2(1) + 11L = 57
2 + 11L = 57
11L = 55
L = 5
Now substitute the values of M and L into equation (1) -
S + 1 + 5 = 12
S + 6 = 12
S = 6 - 6
S = 0
Therefore, the solution is -
S = 0 (no small pizzas)
M = 1 (1 medium pizza)
L = 5 (5 large pizzas)

You are the purchasing manager of an airline company and have a spending goal of $4950 million for the purchase of new aircraft to seat a total of 5850 passengers. Your company has a policy of supporting U.S. industries, and you have been instructed to buy twice as many Boeings as Airbuses. Given the selection of three aircraft, how many of each should you order?
The number of order of each aircraft is an illustration of simultaneous equations.
You should order 7 Airbus A330-300s, 5 Boeing 767-300ERs and 9 Boeing Dreamliner 787-9s
To do this, we make use of the following representations:
A represents Airbus A330-300sB represents Boeing 767-300ERsC represents Boeing Dreamliner 787-9sFrom the question, we have the following equations
\(\mathbf{330A + 270B + 240C = 5850}\) ----the number of passengers
\(\mathbf{B + C = 2A}\) --- the relationship between the number of planes
\(\mathbf{250A + 200B + 240C =4950 }\) --- the budget
Make A the subject in \(\mathbf{B + C = 2A}\)
\(\mathbf{A=\frac{1}{2}(B + C)}\)
Substitute \(\mathbf{A=\frac{1}{2}(B + C)}\) in \(\mathbf{330A + 270B + 240C = 5850}\)
\(\mathbf{330 \times \frac{1}{2}(B + C) + 270B + 240C = 5850}\)
\(\mathbf{165B + 165C + 270B + 240C = 5850}\)
\(\mathbf{435B + 405C = 5850}\)
Divide through by 15
\(\mathbf{29B + 27C = 390}\)
Make C the subject
\(\mathbf{C = \frac{390 - 29B}{27}}\)
Substitute \(\mathbf{A=\frac{1}{2}(B + C)}\) in \(\mathbf{250A + 200B + 240C =4950 }\)
\(\mathbf{250 \times \frac{1}{2}(B + C) + 200B + 240C =4950 }\)
\(\mathbf{125B + 125C + 200B + 240C =4950 }\)
\(\mathbf{325B + 365C =4950 }\)
Divide through by 5
\(\mathbf{65B + 73C =990}\)
Substitute \(\mathbf{C = \frac{390 - 29B}{27}}\)
\(\mathbf{65B + 73\times\frac{390 - 29B}{27} =990}\)
Multiply through by 27
\(\mathbf{65B \times 27+ 73\times(390 - 29B) =990 \times 27}\)
\(\mathbf{1755B+ 28470 - 2117B =26730}\)
Collect like terms
\(\mathbf{1755B- 2117B =26730 - 28470}\)
\(\mathbf{-362B =-1740}\)
Solve for B
\(\mathbf{B =\frac{1740}{362}}\)
\(\mathbf{B =5}\) --- approximated
Substitute \(\mathbf{B =5}\) in \(\mathbf{C = \frac{390 - 29B}{27}}\)
\(\mathbf{C = \frac{390 - 29 \times 5}{27}}}\)
\(\mathbf{C = \frac{245}{27}}}\)
\(\mathbf{C = 9}\) --- approximated
Recall that: \(\mathbf{A=\frac{1}{2}(B + C)}\)
So, we have:
\(\mathbf{A = \frac{1}{2} \times (5 + 9)}\)
\(\mathbf{A = \frac{1}{2} \times 14}\)
\(\mathbf{A = 7}\)

Step-by-step explanation:
By cosine rule, we have:
AB² = AC² + BC² - 2(AC)(BC)cos(ACB)
⇒ AB² = 7² + 10² - 2(7)(10)cos(73)
⇒ AB² = 49 + 100 - 140cos(73)
⇒ AB² = 149 - 140cos(73)
⇒ AB² = 149 - 140cos(73)
⇒ AB² = 149 - 140(0.292)
⇒ AB² = 149 - 40.88
⇒ AB² = 108.12
⇒ AB = √(108.12)
