ACT scores are normally distributed and from 2015 to 2017, the mean was 20.9 with a standard deviation of 5.6.
To get accepted into OSU, you need at least a 27. What is the z-score you need to get accepted? Enter your answer, rounded to the nearest hundredth.
Answers
Answer:
You need a z-score of at least 1.09 to get accepted.
Step-by-step explanation:
Problems of normally distributed samples are solved using the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore 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 pvalue, we get the probability that the value of the measure is greater than X.
In this question, we have that:
[tex]\mu = 20.9, \sigma = 5.6[/tex]
To get accepted into OSU, you need at least a 27. What is the z-score you need to get accepted?
We need to find Z when X = 27. So
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{27 - 20.9}{5.6}[/tex]
[tex]Z = 1.09[/tex]
You need a z-score of at least 1.09 to get accepted.
In a school, 25 % of the teachers teach basic math. If there are 50 basic math teachers, how many teachers are there in the
school?
Answers
Answer:
200 teachers
Step-by-step explanation:
Let t= teachers
t * 25% = basic math teachers
t *.25 = 50
Divide each side by .25
.25t/.25 = 50/.25
t =200
Answer:
200
Step-by-step explanation:
The 50 basic math teachers are 25% of all the teachers of the school.
You can use a proportion.
50 is to 25% as x is to 100%
50/25 = x/100
10/5 = x/100
5x = 100 * 10
5x = 1000
x = 200
There are 200 teachers.

Ray PA is tangent to circle O at point A, PA= 12 units, and the measure of AR is 60°. Answer the following and justify your answer using angle, arc, and special segments relationships with circles,
a) Find the length of the radius of circle O.
b) Find the length of line OP
Answers
Answer:
a) radius = 6.9288 units
b) OP = 13.857 units
Step-by-step explanation:
a)
As PA is tangent to the circle, the angle OAP is 90°, and if the angle of the arc AR is 60°, the angle AOP is also 60°.
So we can find the angle APO with the sum of internal angles of the triangle AOP:
90 + 60 + APO = 180
APO = 30°
Now, we can find the radius AO using the tangent relation of the angle APO, where the opposite side is the radius AO and the adjacent side is AP:
tangent(30) = AO / AP
0.5774 = AO / 12
AO = 0.5774 * 12 = 6.9288 units
b)
To find the length of OP, we can use the Pythagoras' theorem in the triangle AOP:
OP^2 = AO^2 + AP^2
OP^2 = 6.9288^2 + 12^2 = 192.01
OP = 13.857 units

There are 16 pieces of fruit in a basket, including 2 nectarines. What is the probability that a randomly selected piece of fruit will be a nectarine? Type your answer as a fraction in simplest form.
Answers
Answer:
The probability is 1/8
Step-by-step explanation:
We have 2 nectarines in a total of 16 pieces of fruit in a basket, so the probability of random selected piece of fruit being a nectarine is the number of nectarines over the total number of pieces of fruit:
Probability = Number of nectarines / Total pieces = 2 / 16
To find the fraction in the simplest form, we divide the numerator and denominator by 2:
Probability = (2/2) / (16/2) = 1/8
Answer:
its actually 3/8 trust me

Work out the area of this circle take (pi) to be 3.142 and give your answers to 2 decimal places
Answers
Answer:
A = 63.63 m^2
Step-by-step explanation:
The area of a circle is given by
A = pi r^2 where r is the radius
r = d/2 = 9/2 = 4.5
A = 3.142 * (4.5)^2
A =63.6255 m^2
Rounding to 2 decimal places
A = 63.63 m^2
A cylindrical swimming pool is approximately 12 feet wide and 4 feet deep. About how many gallons of water can the swimming pool contain? Remember that 1 cubic foot is approximately 7.48 gallons.
Answers
Answer:
Step-by-step explanation:
Since the swimming pool is cylindrical, we would find its volume by applying the formula for determining the volume of a cylinder which is expressed as
Volume = πr²h
Where
r represents radius of the cylinder
h represents height
π = constant = 3.14
From the information given,
Diameter = 12 feet
Radius, r = diameter/2 = 12/2 = 6 feet
h = 4 feet
Volume = 3.14 × 6² × 4 = 452.16ft³
Since 1 cubic foot is approximately 7.48 gallons, the number of gallons of water that the swimming pool can contain is
452.16 × 7.48 = 3382.16 gallons

Solve the following system of equations.Express your answer as an ordered pair in the format (a,b),with no spaces between the number or symbols 3x+4y=16 -4x-3y=-19
Answers
Answer:
(4,1)
Step-by-step explanation:
3x + 4y = 16
-4x - 3y = -19
4( 3x + 4y = 16)
3( -4x - 3y = -19)
Distribute
12x + 16y = 64
-12x - 9y = -57
Now subtract both equations
7y = 7
/7 on both sides
y = 1
Substitute y = 1 in one of the equations.
3x + 4y = 16
3x + 4(1) = 16
-4 on both sides
3x = 12
/3 on both sides
x = 4

Work out the number of boxes of book marks and the number of packs of dust covers she
buys
You must show all your working
Answers
Answer:
12 boxes of bookmarks and 8 packs of dust covers.
Step-by-step explanation:
Shelley wants to have at least 250 bookmarks and dust covers for her 250 books.
One box of bookmarks contain 24 bookmarks.
One pack of dust cover contain 36 dust covers.
Shelley buys same number of bookmarks and dust covers.
So, we need to find out LCM(Least Common Multiple) of 24 and 36 to come to a common number that can be bought.
LCM of 24 and 36 is 72.
But, at least 250 bookmarks or dust covers have to be bought. So, we need to find a multiple of 72 which is greater than or equal to 250.
Let us consider the Table of 72:
72, 144, 216, 288, 360 .....
For having enough count of bookmarks and dust covers, at least 288 bookmarks and dust covers have to be bought.
Number of boxes of bookmarks bought = [tex]\frac{288}{24} \Rightarrow 12[/tex]
Number of packs of dust covers bought = [tex]\frac{288}{36} \Rightarrow 8[/tex]
12 boxes of bookmarks and 8 packs of dust covers.

If bracelet Y is chosen first, in how many ways can Jillian give out the bracelets? 1 2 3 4
Answers
Answer:
a) 0.09
b) 2 ways
Step-by-step explanation:
a) Probability Pedro's shot will score will be given as) :
P(score) = 0.30
The probability he will score in 2 consecutive shots will be calculated as:
P(score) * P(score)
= 0.30 * 0.30
= 0.09
Therefore, probability he will score in 2 consecutive shots is 0.09
b) Jillian has 3 bracelets: X, Y, & Z as a gift. If bracelet Y is chosen first, the number of ways Jillian can give out the bracelets since bracelet Y is chosen first, she will have 2 bracelets remaining. So, number of ways to distribute these 2 bracelets are :
= 2!
= 2 * 1
= 2
Which could be in this order:
YXZ or YZX
Therefore, the number of ways if Y is chosen first is = 2 ways
