The probability that X is greater than 70 and less than 90 is; 0.85
How to find the probability?Let X be the binomial random variable with the parameters:
n = 200
p = 0.4
Then, the random variable Z defined as:
Z = (X - np)/(√(np(1 - p)
The probability that X is greater than 70 and less than 90 is expressed as; P(70 < X < 90)
At X = 70, we have;
Z = (70 - (200*0.4))/(√(200 * 0.4(1 - 0.4))
Z = -1.44
At X = 90, we have;
Z = (90 - (200*0.4))/(√(200 * 0.4(1 - 0.4))
Z = 1.44
Thus, the probability would be expressed as;
P(-1.44 < Z < 1.44)
From online p-value calculator, we have;
P(-1.44 < Z < 1.44) = 0.85
Complete question is;
Suppose that X is a binomial random variable with n = 200 and p = 0.4 Approximate the probability that X is greater than 70 and less than 90.

Mary and Keisha run with the same constant speed but in opposite directions. The girls have: A. The same position B. Different accelerations C. Different speeds D. Different velocities
Answer:
D
Explanation:
Mary and Keisha run with the same constant speed but in opposite directions. The girls have different velocities. Hence option D is correct.
What is velocity?According to a particular point of view and a particular unit of time, velocity is the rate at which an object changes position while travelling in one direction. Velocity is a vector quantity. It has both a magnitude and a direction. Therefore, it alters whenever either the speed or the direction do. The meter per second is the accepted unit of magnitude for velocity.
One might refer to an object as accelerating if either the magnitude or direction of the velocity vector changes. An object moving in a circle at a constant speed can be said to accelerate because the direction of the velocity changes. Although the object is moving at a constant speed, its velocity is changing. As a vector, velocity has a fixed magnitude but a fluctuating direction.
Thus, Mary and Keisha run with the same constant speed but in opposite directions. The girls have different velocities. Hence option D is correct.

THIS IS MY EXAM FOUR QUESTIONS CAN SOMEBODY PLZZ HELP ME AN SHOW THE WORK FROM THE BOTTOM OF MY HEART PLZZ
Answer:
Answer of question 1 :
Explanation:
Let x be the legs of ducks
And y be the legs of cows
According to the question,
2x + 4y = 52...…..(i) ( as ducks ahs two legs and as cows has 4 legs)
As he has 21 animals in total so,
x + y = 21...…..(ii)
We have make the equation. We will solve them by eliminatory method or substitution method. Here, I'll go for substitution method.
From equation (ii)
x = 21 - y....…..(iii)
Putting the value of x in equation (i),
2x + 4y = 52
2( 21 - y ) + 4y = 52
42 - 2y + 4y = 52
2y = 52 - 42
y = 10/2
y = 5 ( He has 2 cows)
putting the value of y in equation (ii)
x + y = 21
x + 5 = 21
x = 21 -5
x = 16 ( He has 16 ducks)

Psychology What is one source error associated with self-report inventories, and what is one of its solutions?
Answer:
one source error associated with self-report inventories is that some people aren't very self-aware or may jump to conclusions about their systems or disorders without taking a step back and assessing all of the possibilities. a solution to this would be having the assessment taker speak to a professional, or trying to make them report their symptoms as objectively as possible.
Explanation:
Answer:
One source error is deliberate deception, and one of its solutions is having a lie scale inserted into the assessment. Another source error is social desirability, and one of its solutions is locating questions sensitive to bias and changing or dropping them. Another source error is response set, and two of its solutions are using word variations and writing questions on the assessment in different ways.

Marisol is selling snacks at her school’s soccer games to raise money for a service project. She buys nuts in cases that contain 24 bags and granola bars in cases that contain 20 packages. She sells the nuts for $1.25 a bag and the granola bars for $1.75 a package. If she raised $160 and sold 112 items, how many cases of granola bars did Marisol buy?
Answer:
2 cases of granola bars
Explanation:
This is a classic system of equations type question.
24n + 20gb = 112 as she can only buy the items in these quantities and this is how many she bought in total
30n + 35gb = 160 as this is how much money she earns per case
I like to solve using elimination when possible. So we can multiply the first equation by 1.25
30n + 25gb = 140 then subtract this from the second equation
10 gb = 20 then divide by 10
gb = 2

What do organizations typically analyze as part of an internal analysis, and why?
A few of the factors that entities analyze as part of their internal analysis include the ability of the organization's employees to be competent and competitive in acquiring markets for its products, as well as the costs that all of this will necessitate because these are variables from within the establishment.
What do organizations typically analyze as part of an external analysis, and why?Providers, distribution companies, and consumers of the company's products and resources are some of the things that companies analyze as part of an environmental analysis because they are part of the outside world that gives an organization both possibilities to enhance output as well as threats that lag them behind.

Bramble Corp. manufactures a product with a standard direct labor cost of two hours at $17 per hour. During July, 1100 units were produced using 2400 hours at $17.3 per hour. The labor price variance was $4120 F. $4120 U. $720 U. $3400 U.
Based on the standard price, the actual price and the actual hours, the labor rate variance for Bramble Corp. is $720 Unfavorable.
What is the labor rate variance?Labor rate variance refers to the difference between the amount that a company budgeted to pay workers and the amount it will actually pay them.
The labor rate variance can be found as:
= (Standard price - Actual price) x Actual hours
Solving for labor rate variance gives:
= (17 - 17.30) x 2,400 hours
= 0.3 x 2,400
= $720 Unfavorable
The Variance is unfavorable because standard price is less than actual price.
This means that the company incurred more costs with the labor than they anticipated and so the budgeted income will be less than the actual income thanks to the higher labor expenses.
In conclusion, the labor price variance for Bramble Corp. is $720 Unfavorable.
