in the diagram below of triangle C D E,F is a midpoint of C D and G is a midpoint of D E, if F G = 9x -59, C E = 34 - x, what is the measure of C E?
Answer:
Hey, I'm not sure if my assumptions were correct or not because there is no diagram. I assumed the triangle to be equilateral, the two lines are parallel and the height of the triangle is 1.
Step-by-step explanation:
Since the triangle is parallel*, we can just use ratio and proportion.
[tex] \frac{rise}{run} = \frac{1}{34 - x} = \frac{0.5}{9x - 59} \\ \frac{1}{34 - x} = \frac{0.5}{9x - 59} \\ 1(9x - 59) = 0.5(34 - x) \\ 9x - 59 = 17 - .5x \\ 9x + 0.5x = 59 + 17 \\ 9.5x = 76 \\ x = \frac{76}{9.5} \\ x = 8[/tex]
Now that we had found the value of x, we will now substitute that to both equations to get the respective distances.
CE = 34 - x = 34 - 8 = 26

The probability of tails of a weighted coin is 0.8. The number of tails is noted each of the 20 times the coin is tossed. If this procedure is repeated 75 times, what type of distribution is simulated?
Answer:
A sampling distribution of the sample proportion with n = 20 and p = 0.8
Step-by-step explanation:
We are given that
The probability of tails of a weighted coin, p=0.8
n=20
We have to find the type of distribution is simulated if this procedure repeated 75 times .
Random variable is a proportion of number of tails therefore, type of distribution is sampling distribution of the sample proportion.
We have n=20 and p=0.8
Hence, we can say that type of distribution is simulated is given by
A sampling distribution of the sample proportion with n = 20 and p = 0.8
Answer:
I chose answer D. A binomial distribution with n=20 and p=0.8, No clue if correct or not

6. Andre and Clare are discussing triangle ABC that has a right angle at C and a
hypotenuse of length 15 units. Andre thinks the triangle could have legs that are 9 and
12 units long. Clare thinks angle B could be 20 degrees and then side BC would be 14.1
units long. Do you agree with either of them? Explain or show your reasoning.
Answer:
BOTH ARE CORRECT
Step-by-step explanation:
Given that:
Triangle ABC Is right angled ;Angle ABC
Hypotenus = 15
If legs are 9 and 12 units long ;
From Pythagoras :
9² + 12² = hypotenus²
81 + 144 = 225²
2.) if:
B = 20° ; BC = will be
Using :
Cos θ = BC / 15
Cos 20 = BC / 15
BC = Cos 20 * 15
BC = 0.939692 * 15
BC = 14.09
BC = 14.1
Enter an algebraic equation for the word sentence. Use x as your variable. A number increased by 6.8 is 8.9.
Answer:
x + 6.8 = 8.9
Step-by-step explanation:
First let's break this sentence down into parts.
A number increased by 6.8 is 8.9.
"A number" - This value is unknown, therefore we will represent it with x.
"increased by" - This signifies that we will be adding.
"is" - This represents the equal sign (=)
Now let's put these together.
x + 6.8 = 8.9
This is your expression.

A coach of a baseball team orders hats for the players on his team. Each hat costs $9.95. The shipping charge for the entire order is $5.00. The total cost of the coach's order is less than $125.00. What inequality can be used to determine the greatest number of hats, h, the coach orders
Answer: 11
Step-by-step explanation:
Based on the information that have been given in the question, we can use the information to form an inequality which goes thus:
5 + 9.95h < 125
9.95h < 125 - 5
9.95h < 120
h < 120/9.95
h < 12.06
h < 12
Therefore since h is less than 12, the greatest number of hat that can be ordered will be 11.
Find the length of BC and BE (show work please)
Answer:
BC = 4 cm
BE = 10.39
Step-by-step explanation:
ABCD is an isosceles trapezoid.
Measures of base angles of an isosceles trapezoid are equal.
[tex]\therefore m\angle ABC = m\angle DCB [/tex]
[tex]\because m\angle DCB = 120\degree [/tex]
[tex]\therefore m\angle ABC = 120\degree [/tex]
[tex] m\angle ABE = 120\degree-90\degree [/tex]
[tex] m\angle ABE = 30\degree [/tex]
in triangle ABE,
[tex]\cos 30\degree =\frac{BE}{12}[/tex]
[tex]\frac{\sqrt 3}{2} =\frac{BE}{12}[/tex]
[tex] BE = \frac{\sqrt 3\times 12}{2} [/tex]
[tex] BE =6\sqrt 3\: cm[/tex]
[tex] BE = 10.39 cm[/tex]
[tex]\sin 30\degree =\frac{AE}{12}[/tex]
[tex]\frac{1}{2} =\frac{AE}{12}[/tex]
[tex] AE = \frac{12}{2} [/tex]
[tex] AE =6 \: cm[/tex]
Next, Draw [tex] CF\perp AD [/tex]
FD = AE = 6
EF = 16 - (AE + FD) = 16 - (6+6) = 16-12
EF = 4 cm
BCFE is a rectangle.
Measures of the opposite sides of a rectangle are equal.
Therefore
BC = EF

In ΔFGH, g = 7.6 inches, h = 3.2 inches and ∠F=160°. Find the length of f, to the nearest 10th of an inch.
In ΔFGH, g = 7.6 inches, h = 3.2 inches and ∠F=160°. Find the length of f, to the nearest 10th of an inch.
=10.7
The length of f from the given triangle FGH is 10.7 inches.
What is cosine rule?The law of cosine states that the square of any one side of a triangle is equal to the difference between the sum of squares of the other two sides and double the product of other sides and cosine angle included between them. The law of cosine states that: a² = b² + c² − 2bc·cosA.
Given that, in ΔFGH, g = 7.6 inches, h = 3.2 inches and ∠F=160°.
Here, f² = 7.6² + 3.2² − 2×7.6×3.2×cos160°
f² = 57.76+10.24-48.64×(- 0.9396)
f² = 68+45.70
f² = 113.7
f = √113.7
f = 10.7 inches
Therefore, the length of f is 10.7 inches.

1. If y varies inversely as x and x = 2 when y = 8, find x when y= 5.
Answer:
16/5

Since y varies inversely as x, then xy = k
2(8) = 16 = k
Therefore, xy = 16
Now, 5x = 16
x = 16/5
How long will the path be.
Given:
The side of the square garden is 30ft.
To find:
The length of the diagonal of the square garden.
Solution:
We know that, the length of the diagonal of a square is
[tex]d=a\sqrt{2}[/tex] ...(i)
Where, a is the the side of the square.
We have,
Side of the square garden = 30 ft.
Putting a=30 in (i), we get
[tex]d=30\sqrt{2}[/tex]
The measure of the diagonal path is [tex]30\sqrt{2}[/tex] ft.
Therefore, the correct option is D.

What probability expression is equivalent to P( / z / > 1.96)?
Answer:
Please check the explanation.
Step-by-step explanation:
Given
P(Z > 1.96)
To determine
What probability expression is equivalent to P(Z > 1.96)
Suppose Z is a standard normal variable.
Therefore,
P(Z > 1.96) = 1 - P(Z ≤ 1.96)
solving
= 1 - Ф(1.96)
= 1 - 0.9750
= 0.0250
The probability of the expression being equivalent to P(z > 1.96) is calculated as 0.0250.
What is a z-score?The z-score is a numerical measurement used in statistics of the value's relationship to the mean of a group of values, measured in terms of standards from the mean.
The given information is P(z > 1.96)
Let z is a standard normal variable. Then we have
P(z > 1.96) = 1 – P(z ≤ 1.96)
P(z > 1.96) = 1 – 0.9750
P(z > 1.96) = 0.0250

Answer:
64 books
Step-by-step explanation:
The first step is to find the number of books that will fit in the shelve per foot
= 40/5
= 8
Therefore the number of books that will fit perfectly in 8-foot shelf can be calculated as follows
= 8×8
= 64
Hence 64 books would fit in 8-foot shelf
