Answer:
0.2187
Step-by-step explanation:
Americans consume on average 92 pounds of chicken per year, with a standard deviation of 10.3 pounds. What is the probability that a sample of 50 people will have consumed an average of 100 pounds or more?
We to find
x ≥ 100 pounds
To solve for the above question, we use the z-score formula
z = (x-μ)/σ, where
x is the raw score = 100 pounds
μ is the population mean = 92 pounds
σ is the population standard deviation = 10.3
Hence:
z = (100 - 92)/ 10.3
z = 8/1.46
z = 0.7767
Probability value from Z-Table:
P(x<100) = 0.78133
P(x>100) = 1 - P(x<100) = 0.21867
Approximately = 0.2187
Therefore, the probability that a sample of 50 people will have consumed an average of 100 pounds or more is 0.2187

The distance between Rosa's house and her school is 4 1/2 of a mile. She ran 3 mile. What fraction of the distance between her house and her school, did Rosa run?
Answer:
Rosa ran [tex]\frac{2}{3}[/tex] of the total distance between her house and her school.
Step-by-step explanation:
Distance between Rosa's house and her school = [tex]4\frac{1}{2}[/tex] miles ≈ 4.5 miles
She ran distance = 3 miles
Therefore, fraction of the total distance between her house and school she run = [tex]\frac{\text{Distance run by Rosa}}{\text{Total distance between her house and school}}[/tex]
= [tex]\frac{3}{4.5}[/tex]
= [tex]\frac{30}{45}[/tex]
= [tex]\frac{2}{3}[/tex]
Therefore, Rosa ran [tex]\frac{2}{3}[/tex] of the total distance between her house and her school.
In the figure shown, BC is parallel to
AD and AB =
AB = CD. What is the
perimeter of quadrilateral ABCD ?
Answer:
52 units.
Step-by-step explanation:
If we drop a perpendicular line from point C to AD and call the point ( on AD) E we have a right triangle CED.
Now CE = 6 and as the whole figure is symmetrical about the dashed line,
ED = (26 - 10)/2
= 8.
So by Pythagoras:
CD^2 = 6^2 + 8^2 = 100
CD = 10.
So, as AB = CD,
the perimeter = 10 + 26 + 2(8)
= 52.
The perimeter of the Quadrilateral ABCD is 56
Given that :
BC = 10
AD = 26
AM = ND = (26 - 10) / 2 = 16 / 2 = 8
Using Pythagoras:
AB² = AM² + BM²
AB² = 8² + 6²
AB² = 64 + 36
AB² = 100
AB = √100
AB = 10
AB = CD = 10
THE PERIMETER OF THE QUADRILATERAL WILL BE :
AB + BC + CD + AD
10 + 10 + 26 + 10 = 56
HENCE, The PERIMETER of the quadrilateral ABCD = 56

Lance the alien is 5 feet tall. His shadow is 8 feet long. At the same time of day, a tree's shadow is 32 feet long. What is the height of the tree?
Answer:
20 feet
Step-by-step explanation:
Lance the alien is 5 feet tall. His shadow is 8 feet long. At the same time of day, a tree's shadow is 32 feet long. What is the height of the tree?
We solve this using proportion of
Height/ Shadow
= 5/8 = x/32
Cross Multiply
8x = 5 × 32
x = 5 × 32/8
x = 20 feet
The height of the tree is 20 feet

If two sweaters and four shirts cost $150, and four sweaters and three shirts cost $200, find the price of each shirt and each sweater.
Answer:
shirt = $20
sweater = $35
Step-by-step explanation:
This question would be solved using simultaneous equation
Let the price of sweater be represented by a
Let the price of shirt be represented by b
The following equations can be derived from the question
2a + 4b = 150 equation 1
4a + 3b = 200 equation 2
Multiply equation 1 by 2
4a + 8b = 300 equation 3
Subtract equation 2 from 3
5b = 100
divide both sides of the equation by 5
b = 20
substitute for b in equation 1
2a + 4(20) = 150
2a + 80 = 150
collect like terms
2a = 150 - 80
2a = 70
divide both sides by 2
a = 35
Price of sweater = $35
Price of shirt = $20

A father is 30 years older than his son. In 12 years the father will be three times as old as his son. Find their present ages.
ASAP PLZ
i am garbage dont listen to the old answer
Answer:
Son is 3. Father is 33.
Step-by-step explanation:
Let the present age of the son be 'x' years.
Then father's age will be (x + 30) years
Given : After 12 years, the father will be three times as old as his son. Therefore,
(x + 12)3 = x + 30 + 12
3x + 36 = x + 42
3x - x = 42 - 36
2x = 6
x = 3
The present age of son is 3 years and the present age of the father is 3 + 30 = 33 years.

Three teachers buy prizes to put in the prize bin at school. Mrs. Maiers spends $7.68 on stickers. Mr. Lang spends $11.52 on balloons. Mrs. Connor spends $17.64 on pencils.
Answer: $12.28
Step-by-step explanation:
Here's the complete question:
Three teachers bought prizes to put in a bin at school. Mrs. Maier spent $7.68 on stickers. Mr. Lang spent $11.52 on balloons. Mrs. Connor spent $17.64 on pencils. The teachers divided the cost evenly. How much did each teacher pay?
Cost of stickers = $7.68
Cost of balloons = $11.52
Cost of pencils = $17.64
Total spent = $7.68 + $11.52 + $17.64 = $36.84
The amount that each teacher will pay when the total cost is evenly shared will be:
= $36.84 / 3
= $12.28

Answer:
25% or .25
Step-by-step explanation:
fist find the number it increased by minus 250000 from 200000
250000 - 200000 = 50000
then divide the increase by the original
50000/200000 = .25 or 25%
