37:53 Bok Suppose that x has a binomial distribution with n=202 and p= 0.44. (Round np and n(1-p) answers to 2 decimal places. Round your answers to 4 decimal places. Round z values to 2 decimal place
The mean (µ) and standard deviation (σ) of the binomial distribution with n=202 and p=0.44 are 88.88 and 7.8959, respectively. The probability of obtaining x=53 is approximately 0.0561, and the z-score for x=37 is -6.55.
To find the mean (µ) and standard deviation (σ) of the binomial distribution, we use the formulas µ = np and σ = sqrt(np(1-p)), where n is the number of trials and p is the probability of success.
Given n = 202 and p = 0.44, we can calculate the mean and standard deviation as follows:
µ = 202 * 0.44 = 88.88 (rounded to 2 decimal places)
σ = sqrt(202 * 0.44 * (1 - 0.44)) = 7.8959 (rounded to 4 decimal places)
Now, let's suppose we want to find the probability of obtaining a specific value of x, let's say x = 53. We can use the formula for the binomial probability:
[tex]P(x) = C(n, x) * p^x * (1 - p)^{n - x}[/tex]
Substituting the values, we have:
[tex]P(53) = C(202, 53) * (0.44)^{53} * (1 - 0.44)^{202 - 53}[/tex]
Using a binomial calculator or software, we can find the probability as approximately 0.0561 (rounded to 4 decimal places).
Finally, if we want to calculate the z-score for a given value of x, we can use the formula:
z = (x - µ) / σ
For x = 37, the z-score would be (37 - 88.88) / 7.8959 = -6.55 (rounded to 2 decimal places).
In conclusion, for a binomial distribution with n = 202 and p = 0.44, the mean is 88.88 and the standard deviation is 7.8959. The probability of obtaining x = 53 is approximately 0.0561. The z-score for x = 37 is -6.55.

Marsha’s scores on seven tests were: 82, 78, 77, 93, 85, 91, and 86. What does she need to score on her next test to have an 86 average?
Answer:
The score of her next test is 96
Step-by-step explanation:
If there is a set of data with x terms, then the average is the sum of their values divided by x
Average = sum of values of the x terms ÷ x
We will use this rule to solve the question
∵ Marsha's scores on 7 test were 82, 78, 77, 93, 85, 91, 86
→ Find her total scores on the seven tests
∴ Her total scores = 82 + 78 + 77 + 93 + 85 + 91 + 86 = 592
∴ Her total scores on the 7 tests is 592
∵ Her average score on the 8 test is 86
→ Use the rule of the average to find her total score in the 8 test
∵ 86 = total scores ÷ 8
→ Multiply both sides by 8
∴ 86 × 8 = total scores × 8 ÷ 8
∴ 688 = total scores
∴ Her total scores on the 8 tests is 688
∵ Her total scores on the 7 test = 592
∵ Her total scores on the 8 test = 688
→ The difference between both totals is the score of her next test
∴ The score of her next test = 688 - 592 = 96
∴ The score of her next test is 96

Answer:
x1 = -8 and x2 = 9?
= x - 8 / x = 2 / x + 9
= Let's solve your equation step-by-step.
= x − 8x = 2x + 9
= x + − 8x = 2x + 9
Multiply all terms by x and cancel:
xx + −8 = 2 + 9x
x² −8 = 9x + 2 ( Simplify both sides of the equation )
x² − 8 − (9x + 2) = 9x + 2 − (9x + 2) (Subtract 9x+2 from both sides)
x² − 9x − 10 = 0
( x + 1 )( x − 10 ) = 0 (Factor left side of equation)
x +1 = 0 or x − 10 = 0 (Set factors equal to 0)

At top cruising speed, a mako shark can swim 4 kilometers in 1/10 hour. A blue whale can swim 5 kilometers in 1/4 an hour which animal swims faster at a top cruising speed? How much faster? Show your work.
Answer: Mako shark
Step-by-step explanation:
We will calculate the speed of the sharks to know which is faster.
A mako shark can swim 4 kilometers in 1/10 hour.
Speed = Distance/Time
= 4/(1/10)
= 40km/hour
A blue whale can swim 5 kilometers in 1/4 an hour.
This shows that the Mako shark is faster as it swims at rate of 40km/hour and the blue whale swims at 5km/hour. It's faster by 35km.
= 40km - 5km
= 35km

Step-by-step explanation:
Mark wants to improve his free throw percentage in basketball. He has shot 1250 free throws over the last 20 days. He shot either 50 or 100 free throws a day. Formulate and solve a system of equations to determine how many times Mark has shot 100 free throws for the day.
Answer:
Let's use a for number of days when he shot 50 shots and b for number of days when he shot 100 shots.
We have:
a + b = 20
We also know that he shot total of 1250 shots:
50a + 100 b = 1250
We have two equations. We can solve them for a and b. Let's rearange first equation for a:
a= 20 - b
We insert this into second equation:
50 * (20 - b ) + 100b = 1250
1000 - 50b + 100b = 1250
50b = 250
b = 5
a = 20 - 5
a = 15
Mark shot 100 shots on 5 day
Answer: x = 15, y = 5
Step-by-step explanation:
x + y = 20 The number of days equals 20
50x + 100y = 1250 The free throws per day add up to 1250
Solve by substituion:
rewrite the first equation to get the value for x
x = -y +20 Subsstitute for x in the second equation
50(-y +20) + 100y = 1250
-50y + 1000 + 100y = 1250 Subtract 1000 from both sides and simplify y
50y = 250 Divide both sides by 50
y = 5
substitute in the first equation and solve for x
x + 5 = 20
x = 15
Substitute into the second equation to check
50(15) + 100(5) = 1250
750 + 500 = 1250
1250 = 1250 True

For the constraints given below, which point is in the feasible region of this maximization problem? 14X+4Y≤28
X−Y≤2
x=−1,y=2.5
x=−1,y=1
x=4,y=2
x=2,y=1
x=1,y=1
The points that lie in the feasible region of this maximization problem are (-1,1) and (1,1).
The given constraints are: 14X + 4Y ≤ 28 and X − Y ≤ 2
In order to determine which of the points belong to the feasible region of this maximization problem, we need to check each point one by one. Let's evaluate each point and check which of the points lie in the feasible region. The points are given as below:x = −1, y = 2.5
The two constraints are:14X + 4Y ≤ 28 and X − Y ≤ 2
For the point (x,y) = (-1,2.5), we have:
14(-1) + 4(2.5) = 7 > 0;
Therefore, the point (-1,2.5) satisfies the first constraint.
Next, we need to check whether the point (-1,2.5) satisfies the second constraint:X − Y = -1 - 2.5 = -3.5 < 2
Since the second constraint is not satisfied, (-1,2.5) is not in the feasible region.
x = −1, y = 1
For the point (x,y) = (-1,1), we have:14(-1) + 4(1) = 10 > 0;
Therefore, the point (-1,1) satisfies the first constraint
.Next, we need to check whether the point (-1,1) satisfies the second constraint:X − Y = -1 - 1 = -2 < 2
Since the second constraint is satisfied, (-1,1) is in the feasible region.
x = 4, y = 2For the point (x,y) = (4,2), we have:14(4) + 4(2) = 64 > 0;
Therefore, the point (4,2) satisfies the first constraint.Next, we need to check whether the point (4,2) satisfies the second constraint:X − Y = 4 - 2 = 2 < 2
Since the second constraint is not satisfied, (4,2) is not in the feasible region.
x = 2, y = 1
For the point (x,y) = (2,1), we have:
14(2) + 4(1) = 32 > 0;
Therefore, the point (2,1) satisfies the first constraint.Next, we need to check whether the point (2,1) satisfies the second constraint:X − Y = 2 - 1 = 1 < 2
Since the second constraint is satisfied, (2,1) is in the feasible region.
x = 1, y = 1
For the point (x,y) = (1,1), we have:
14(1) + 4(1) = 18 > 0;
Therefore, the point (1,1) satisfies the first constraint.
Next, we need to check whether the point (1,1) satisfies the second constraint:X − Y = 1 - 1 = 0 < 2
Since the second constraint is satisfied, (1,1) is in the feasible region.
Hence, the two points that belong to the feasible region are (-1,1) and (1,1).
Therefore, the correct answer is: The points that lie in the feasible region of this maximization problem are (-1,1) and (1,1).

please help!! If the wind is blowing at 20 miles per hour, you can find the wind-chill temperature W (in degrees Fahrenheit) by using the equation W = 1.42T - 38.5, where T is the actual temperature (in degrees Fahrenheit). Solve this equation for T and write a reason for each step. What is the actual temperature if the wind chill temperature is -24.3°F and the wind is blowing at 20 miles per hour? thank you
If the wind chill temperature is -24.3°F, actual temperature of the wind will be 10°F.
Equation for the chill temperature has been given as,
W = 1.42T - 38.5Here, W = Chill temperature
T = Actual temperature
Solve this equation for the value of T,
W = 1.42T - 38.5
W + 38.5 = 1.42T - 38.5 + 38.5 (Add 38.5 on each side)
W + 38.5 = 1.42T
[tex]T=\frac{W+38.5}{1.42}[/tex] (Divide each side by 1.42)
For W = -24.3°F
[tex]T=\frac{-24.3+38.5}{1.42}[/tex] (Substitute the value of W in the equation)
T = 10° F
Therefore, actual temperature will be 10°F if the wind chill temperature is -24.3°F.

the volume of a rectangular pyramid is 512 units 3 3 . if the length of the rectangular base measures 8 units and the width of the rectangular base measures 12 units, find the height of the pyramid.
The height of the rectangular pyramid is 16 units.
To find the height of the rectangular pyramid, we can use the formula for the volume of a pyramid:
Volume = (1/3) * base area * height
Given that the volume of the rectangular pyramid is 512 units^3, and the length of the rectangular base is 8 units and the width is 12 units, we can find the base area:
Base Area = length * width = 8 * 12 = 96 units^2
Now we can substitute the values into the volume formula:
512 = (1/3) * 96 * height
To solve for the height, we can isolate it by multiplying both sides of the equation by 3/96:
512 * 3/96 = height
Simplifying the right side of the equation:
16 = height
The rectangular pyramid is 16 units tall as a result.

P(X=x) 0.1 0.2 0.3 0.2 0.2
Step 3 of 5:
Find the standard deviation. Round your answer to one decimal place.
Step 4 of 5:
Find the value of P(X≥5)P(X≥5). Round your answer to one decimal place.
Step 5 of 5:
Find the value of P(X≤3)P(X≤3). Round your answer to one decimal place.
The standard deviation is approximately 1.3, rounded to one decimal place. The values for P(X≥5) and P(X≤3) are approximately 0.2 and 0.6, respectively, rounded to one decimal place.
To determine the standard deviation, we first need to calculate the mean. We can do this by multiplying each value of 'x' by its corresponding probability and summing them up:
Mean (μ) = (1*0.1) + (2*0.2) + (3*0.3) + (4*0.2) + (5*0.2) = 0.1 + 0.4 + 0.9 + 0.8 + 1.0 = 3.2
Next, we can calculate the variance (σ^2) by squaring the differences between each 'x' value and the mean, multiplying by their probabilities, and summing them up:
Variance (σ²) =
[tex][(1-3.2)^2 * 0.1] + [(2-3.2)^2 * 0.2] + [(3-3.2)^2 * 0.3] + [(4-3.2)^2 * 0.2] + [(5-3.2)^2 * 0.2]= \\(-2.2)^2 * 0.1] + [(-1.2)^2 * 0.2] + [(-0.2)^2 * 0.3] + [(0.8)^2 * 0.2] + [(1.8)^2 * 0.2]= \\4.84 * 0.1 + 1.44 * 0.2 + 0.04 * 0.3 + 0.64 * 0.2 + 3.24 * 0.2= 0.484 + 0.288 + 0.012 + 0.128 + 0.648 \\= 1.56[/tex]
Finally, the standard deviation (σ) is the square root of the variance:
Standard Deviation (σ) = √1.56 ≈ 1.25 (rounded to one decimal place)
To find P(X≥5), we add up the probabilities of all 'x' values greater than or equal to 5:
P(X≥5) = P(X=5) = 0.2
To find P(X≤3), we add up the probabilities of all 'x' values less than or equal to 3:
P(X≤3) = P(X=1) + P(X=2) + P(X=3) = 0.1 + 0.2 + 0.3 = 0.6
Therefore, the values are:
Standard Deviation ≈ 1.3
P(X≥5) ≈ 0.2
P(X≤3) ≈ 0.6
