J.V. Lin is an Olympic athlete competing in the women's javelin throw. The distances of her successful throws (in meters) are normally distributed with mean distance 60 meters and standard deviation 4 meters. (Round to the nearest percent and enter each of your answers as a whole number between 0 and 100.) (a) (2 points) What is the probability that on her first throw, J.v. Lin beats her mean distance? probability = ________%(b) (3 points) The current leader in the Olympics finals has thrown a distance of 66.5 meters. J.V. Lin has one attempt left to beat the leader's throw. What's the probability that Lin beats this throw? probability _______%
Answer:
a) 50%
b) 5%
Step-by-step explanation:
Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.
Normally distributed with mean distance 60 meters and standard deviation 4 meters.
This means that [tex]\mu = 60, \sigma = 4[/tex]
(a) (2 points) What is the probability that on her first throw, J.v. Lin beats her mean distance?
This is, as a proportion, 1 subtracted by the pvalue of Z when X = 60. So
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{60 - 60}{4}[/tex]
[tex]Z = 0[/tex]
[tex]Z = 0[/tex] has a pvalue of 0.5
1 - 0.5 = 0.5
0.5*100% = 50%
50% probability.
(b) (3 points) The current leader in the Olympics finals has thrown a distance of 66.5 meters. J.V. Lin has one attempt left to beat the leader's throw. What's the probability that Lin beats this throw?
This is 1 subtracted by the pvalue of Z when X = 66.5. So
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{66.5 - 60}{4}[/tex]
[tex]Z = 1.63[/tex]
[tex]Z = 1.63[/tex] has a pvalue of 0.95
1 - 0.95 = 0.05
0.05*100% = 5%
5% probability.

Find the 96th term of the arithmetic sequence-30,-32,34
Answer:
a = -30
d = -32 - (-30) = -2
n = 96
So, using A.P. formula-
Tn = a + (n-1) d
T96 = -30 + (96-1) -2
T96 = -30 + (95) -2
T96 = -30 - 190
T96 = -220

Enter the area of the triangle in square meters.Round your answer to the nearest hundredth.
Answer:
6.24
Step-by-step explanation:
To find the area of the triangle, it is base times height divided by 2 after you multiply. Height is 90 degrees from base so remember that.
In this example, do (2.6 x 4.8)/2
Equals 6.24

(b) ... because of the AA similarity postulate
Step-by-step explanation:
The problem statement tells you that you are showing ∠F≅∠C. We already know that ∠A≅∠D, because they are both marked as right angles. Thus the given mapping results in two of the three angles being shown congruent, allowing you to conclude ...
ΔABC ~ ΔDEF because of the AA similarity postulate . . . . choice B
Liliana used 4 dark power crystals to raise 14 zombie soldiers. She wants to know how many zombie soldiers (z) left parenthesis, z, right parenthesis she can raise with 10 dark power crystals.
Answer:
So.. Liliana used 4 crystals to race 14 zombie soldiers.
14 / 4 = 3.5. She can race 3.5 zombie soldiers if she uses 1 crystal. So, all you need to do it multiply 3.5 by 10 and you end up with 35.
So, Liliana is able to race 35 zombie soldiers with 10 power crystals.

what operation do you use to convert from a larger measurement unit to a smaller measurement unit?explain why.
Answer:
Multiplication
Step-by-step explanation:
To convert from a larger unit to a smaller unit, we multiply. This is because the number will become greater since the unit is smaller.
Example:
1 m ⇒ ×100 ⇒ 100 cm
We use division when converting from a smaller unit to a larger unit since the number will become smaller as the unit becomes greater.
Example:
100 cm ⇒ ÷100 ⇒ 1 m

Daniela painted a photo that was 4/5 afoot by 1 7/8 of afoot. What was the area?
Answer:
[tex]\frac{3}{2}[/tex] square feet
Step-by-step explanation:
The dimensions of the photo is 4/5 by 1 7/8 of a foot.
But,
1 7/8 = [tex]\frac{15}{8}[/tex] feet
So that,
length of the photo = [tex]\frac{15}{8}[/tex] feet
width of the photo = [tex]\frac{4}{5}[/tex] feet
The area of the photo = length x width
= [tex]\frac{15}{8}[/tex] x [tex]\frac{4}{5}[/tex]
= [tex]\frac{60}{40}[/tex]
= [tex]\frac{3}{2}[/tex]
Area of the painted photo is [tex]\frac{3}{2}[/tex] square feet.

Karim began his day by drinking 1 1/8
cups of milk at breakfast. By the end of the day, he drank a total of 2 2/3
cups of milk.
Which equation and solution correctly represent the amount of milk in cups, m , Karim drank after breakfast?
Answer:
A. 1⅛ + m = 2⅔
[tex] m = 1\frac{13}{24} [/tex]
Step-by-step explanation:
Cups of milk at breakfast = 1⅛
Cups of milk after breakfast = m
Total cups of milk by the end of the day = 2⅔
Thus:
Total cups of milk by the end of the day = cups of milk at breakfast + cups of drink after breakfast
Therefore:
1⅛ + m = 2⅔ (equation)
Solve for m
Subtract 1⅛ from each side
m = 2⅔ - 1⅛
Convert to improper fraction
m = 8/3 - 9/8
m = (64 - 27)/24 = 37/24
[tex] m = 1\frac{13}{24} [/tex]
