What is 10 times as much as .06
Answer:
0.6
Step-by-step explanation:
If you do 10 times .06 you get 0.6.
You are the coach of a basketball team that is currently looking for new players. One of the criteria for selection as a player is that the person must be above a particular height. Ideally, you want your next player to be as tall as possible. However, you do not want to rule out any potential players by making the cut-off height too strict. You decide that accepting players within the top 2.5% height bracket will be reasonable for your team. Assume that the height of all people follows a normal distribution with a mean of 70.3 in and a standard deviation of 2.1 in. Calculate the cut-off height (C) that ensures only people within the top 2.5% height bracket are allowed into the team. Give your answer in inches to the nearest inch.C = ______ in
Answer:
The value is [tex]x = 74.416 \ in[/tex]
Step-by-step explanation:
From the question we are told that
The mean is [tex]\mu = 70.3\ in[/tex]
The standard deviation is [tex]\sigma = 2.1\ in[/tex]
Generally the probability of getting people with height in the top 2.5% is mathematically represented as
[tex]P(X > x ) = P(\frac{X - \mu }{\sigma} > \frac{x - 70.3 }{2.1 } ) = 0.025[/tex]
Generally
[tex]\frac{X - \mu }{\sigma} = Z (The \ standardized \ value \ of X )[/tex]
=> [tex]P(X > x ) = P(Z > \frac{x - 70.3 }{2.1 } ) = 0.025[/tex]
Generally the critical value of 0.025 from the normal distribution table is
[tex]Z_{0.025} = 1.96[/tex]
So
[tex]\frac{x - 70.3 }{2.1 } = 1.96[/tex]
=> [tex]x = 74.416 \ in[/tex]
The cut-off height will be "74.416 in".
Probability:This same probability of an occurrence occurring is defined by probability. There are several real-life scenarios in something we should forecast the result of such an occurrence.
According to the question,
Mean, μ = 70.3 in
Standard deviation, σ = 2.1 in
Now,
The probability of getting people with height be:
→ P(X > x) = P([tex]\frac{X -\mu}{\sigma} > \frac{x-70.3}{2.1}[/tex])
= 0.025
We know,
Z = [tex]\frac{X- \mu}{\sigma}[/tex]
→ P(X > x) = P(Z > [tex]\frac{x-70.3}{2.1}[/tex])
= 0.025
The critical value be:
[tex]Z_{0.025}[/tex] = 1.96
hence,
The cut-off height be:
[tex]\frac{x-70.3}{2.1}[/tex] = 1.96
x = 74.416 in
Thus the above answer is correct.

Ok so I wanna know how to solve this. Is it like (3x+6)+24=(2x+8) or like (3x+6)+(2x+8)+24=180
Answer:
24+(2x+8)=3x+6 is the way you set it up
26 is the anser
Step-by-step explanation:
24+2x+8=3x+6
add the 24 and 8
2x+32=3x+6
subtract 6 from both sides
2x+26=3x
subtract 2x from both sides
x=26
Determine the value of X 12,9, 3
The value of x from the given proportion is 4.
The given numbers 12, 9 and 3 are proportions.
What are proportions?Proportion, in general, is referred to as a part, share, or number considered in comparative relation to a whole. Proportion definition says that when two ratios are equivalent, they are in proportion. It is an equation or statement used to depict that two ratios or fractions are equal.
To find the value of x:
So, 12:x::9:3
⇒ 12×3=x×9
⇒ 9x=36
⇒ x=36/9
⇒ x=4
Therefore, the value of x from the given proportion is 4.

Answer:
use the ASA postulate with alternate interior angles
Step-by-step explanation:
Congruence in general
For proving triangle congruence, there are basically 4 ways to do it. All require at least one side. They are ...
SSS - 3 corresponding sides are shown to be congruentSAS - two corresponding sides and the angle between them are shown to be congruentASA - two corresponding angles and the side between them are shown to be congruent (this one is used here)AAS - two corresponding angles and the side next to (a particular) one of them are shown to be congruentWhen applied to right triangles, the right angle counts as one of the angles, and two sides determine the third, so these can become the LL, HL, HA, LA theorems, where the letters (H, L, A) stand for (hypotenuse, leg, angle), respectively.
__
Approach to this problem
Of course, you're familiar with the relationship between angles where a line crosses parallel lines. Those relationships can help you identify two congruent angles in each triangle. The fact that the triangles share a side between those angles gives you a clue that you will be using the ASA postulate for your proof.
Specifics
1. AB ║ CD and AD ║ BC . . . . given
2. ∠1≅∠3 . . . . alternate interior angles at a transversal of parallel lines are congruent
3. AD≅DA . . . . reflexive property of congruence
4. ∠2≅∠4 . . . . alternate interior angles at a transversal of parallel lines are congruent

(2x + 21) + 90 degrees + x = 180 degrees
(2x + 21) + x = 90 degrees
3x + 21 = 90
3x = 69
x = 23 degrees

Which is the equation of a line that has a slope of -2/3 and passes through point -3 -1?
Answer: y= -2x/3 -3
Step-by-step explanation:
Substitute the x and y values from the given coordinate into the slope-intercept formula and solve for b
y = mx + b
-1 = -2/3(-3) + b
-1 = 2 + b
-1 -2 = b
-3 = b The y-intercept is -3
the equation: y = -2x/3 - 3

A school sold 51 less children’s tickets than adult tickets for the school play. Adult tickets cost $1.25 and children’s tickets cost $0.75. A total of $129.75 was taken in. How many of each kind were sold?
-pls provide work :)
Answer:
80 adult tickets and 29 children tickets
Step-by-step explanation:
c + 51 = a
51 = a - c
c = a - 51
a*1.25 + c*0.75 = 129.75
a = 100 c = 49 a + c = 161.75
a = 80 c = 29 a + c = 121.75

Step-by-step explanation:
From the graph, we can tell that slope is 2 because if we go up 2 units up from (0,4) which is point Q and then go right 1 unit, the slope is 2. The y intercept is (0,4)
y = mx + b
m --> slope
b --> y-intercept
y = 2x+4

each basket?
Three baskets contain three consecutive odd numbers of apples. There are 105 apples in total. How many apples are
Enter the numbers from least to greatest.
==================================
Explanation:
Consecutive integers are integers like 1,2,3,... or 6,7,8... so they are integers that follow one after another.
Consecutive odd integers are sequences like 3,5,7,... or 21,23,35... meaning they are odd integers following one after another as close as possible.
If x is some integer, then 2x is always even and 2x+1 is always odd
let 2x+1 be that first odd integer
adding on 2 leads to the next odd integer: (2x+1)+2 = 2x+3
adding on another 2 leads to the next one: (2x+3)+2 = 2x+5
The three expressions
2x+1
2x+3
2x+5
represents three consecutive odd integers. They must add to 105
(2x+1)+(2x+3)+(2x+5) = 105
(2x+2x+2x)+(1+3+5) = 105
6x+9 = 105
6x = 105-9
6x = 96
x = 96/6
x = 16
Meaning that
2x+1 = 2(16)+1 = 33 = first odd integer
2x+3 = 2(16)+3 = 35 = second odd integer
2x+5 = 2(16)+5 = 37 = third odd integer
As a check
33+35+37 = 105
which confirms the answer
