Answer:
4.4in
Step-by-step explanation:
Answer:
x ≈ 4.4 in
Step-by-step explanation:
Using Pythagoras' identity in the right triangle
with legs 2.4 and (7.4 ÷ 2) = 3.7 , x is the hypotenuse, then
x² = 2.4² + 3.7² = 5.76 + 13.69 = 19.45 ( take square root of both sides )
x = [tex]\sqrt{19.45}[/tex] ≈ 4.4 in ( to the nearest tenth )
A band sold out 2 of it's last 6 shows. What is the experimental probability that the band's next show will be sold out
Answer:
1/3
Step-by-step explanation:
Probability calculates the likelihood of an event occurring. The likelihood of the event occurring lies between 0 and 1. It is zero if the event does not occur and 1 if the event occurs.
For example, the probability that it would rain on Friday is between o and 1. If it rains, a value of one ids attached to the event. If it doesn't a value of zero is attached to the event.
Experimental probability is based on the result of an experiment that has been carried out multiples times
Based on experience, the band sells out 2 out of its 6 shows. So, the experimental probability of selling out its next show = 2/6
To transform to the simplest form. divide both the numerator and the denominator by 2

The mean age of 5 women in an office is 23 years old. The mean age of 3 men in an office is 24 years old. What is the mean age (nearest year) of all the people in the office?
Answer:
23
Step-by-step explanation:
Women total age = 5 x 23 = 115
Men total age = 3 x 24 = 72
The mean age of all the people
= (115+72)÷(8)
= 23.375
= 23 (nearest year)
The mean age (nearest year) of all the people in the office is 23
How to determine the mean age?The given parameters are:
5 women = 23 years
3 men = 24 years
Mean is calculated using:
[tex]\bar x = \frac{\sum fx}{\sum f}[/tex]
So, we have:
[tex]\bar x = \frac{23 * 5 + 24 * 3}{5 + 3}[/tex]
Evaluate the quotient
[tex]\bar x = 23[/tex]
Hence, the mean age (nearest year) of all the people in the office is 23

1.3. If Sara draws a red ball and DOES NOT RETURN it, and then she goes to draw a green
ball, is this considered a dependent or independent event?
Answer:
Dependent Event
Step-by-step explanation:
Assume that are 10 balls, such that:
[tex]Red = 6[/tex]
[tex]Green = 4[/tex]
If the balls are replaced after taken, the probability is:
[tex]Pr(Red) = 6/10[/tex]
[tex]Pr(Green) = 4/10[/tex]
This is referred to as independent event; because each selection do not affect the next or previous selection
However, if the balls are not replaced, the probability is:
[tex]Pr(Red) = 6/10[/tex]
[tex]Pr(Green) = 5/(10 - 1) = 5/9[/tex]
We subtracted 1 because there is a reduction in the number of balls when the red ball is not returned.
This is referred to as independent event; because a selection affects the next selection

25 20 15 10 5 nth term
Answer:
-15
Step-by-step explanation:
Answer:
nth term = -5n + 30
Step-by-step explanation:
Given sequence:-
25 20 15 10 5
To find the nth term, we have to find the algebraic expression, Xn.
Xn = dn + b
Here, 'd' means the common difference and 'b' means 'first term -- common difference'
the common difference here is -5
So, b = 25 - (-5)
b = 25 + 5
b = 30
Xn = -5n + 30
Therefore, nth term equals -5n + 30

In parallelogram MNPT, IZM= (6x + 10)° and
mZN= (5x + 10.5)° . How many degrees is ZT?
Answer:
83 degrees
Step-by-step explanation:
We can use the consecutive angle theorem to find the the value of x.
We can do that by doing 5x+10.5+6x+10 = 180
After simplifying, we get 11x+20.5=180
Subtract 20.5 on both sides and you get 11x=159.5.
Divide by 11 on both sides and you get x=14.5
Now we can use opposite angle theorem and set angle N and angle T equal.
That means we could write 5x+10.5 = m<T
We can substitute 14.5 for x and we get 72.5+10.5 = m<T
Simplify and you get 83 = m<T

In Triangle XYZ, measure of angle X = 49° , XY = 18°, and
YZ = 14°. Find the measure of angle Y.
Answer:
There are two choices for angle Y: [tex]Y \approx 54.987^{\circ}[/tex] for [tex]XZ \approx 15.193[/tex], [tex]Y \approx 27.008^{\circ}[/tex] for [tex]XZ \approx 8.424[/tex].
Step-by-step explanation:
There are mistakes in the statement, correct form is now described:
In triangle XYZ, measure of angle X = 49°, XY = 18 and YZ = 14. Find the measure of angle Y:
The line segment XY is opposite to angle Z and the line segment YZ is opposite to angle X. We can determine the length of the line segment XZ by the Law of Cosine:
[tex]YZ^{2} = XZ^{2} + XY^{2} -2\cdot XY\cdot XZ \cdot \cos X[/tex] (1)
If we know that [tex]X = 49^{\circ}[/tex], [tex]XY = 18[/tex] and [tex]YZ = 14[/tex], then we have the following second order polynomial:
[tex]14^{2} = XZ^{2} + 18^{2} - 2\cdot (18)\cdot XZ\cdot \cos 49^{\circ}[/tex]
[tex]XZ^{2}-23.618\cdot XZ +128 = 0[/tex] (2)
By the Quadratic Formula we have the following result:
[tex]XZ \approx 15.193\,\lor\,XZ \approx 8.424[/tex]
There are two possible triangles, we can determine the value of angle Y for each by the Law of Cosine again:
[tex]XZ^{2} = XY^{2} + YZ^{2} - 2\cdot XY \cdot YZ \cdot \cos Y[/tex]
[tex]\cos Y = \frac{XY^{2}+YZ^{2}-XZ^{2}}{2\cdot XY\cdot YZ}[/tex]
[tex]Y = \cos ^{-1}\left(\frac{XY^{2}+YZ^{2}-XZ^{2}}{2\cdot XY\cdot YZ} \right)[/tex]
1) [tex]XZ \approx 15.193[/tex]
[tex]Y = \cos^{-1}\left[\frac{18^{2}+14^{2}-15.193^{2}}{2\cdot (18)\cdot (14)} \right][/tex]
[tex]Y \approx 54.987^{\circ}[/tex]
2) [tex]XZ \approx 8.424[/tex]
[tex]Y = \cos^{-1}\left[\frac{18^{2}+14^{2}-8.424^{2}}{2\cdot (18)\cdot (14)} \right][/tex]
[tex]Y \approx 27.008^{\circ}[/tex]
There are two choices for angle Y: [tex]Y \approx 54.987^{\circ}[/tex] for [tex]XZ \approx 15.193[/tex], [tex]Y \approx 27.008^{\circ}[/tex] for [tex]XZ \approx 8.424[/tex].

1. Find the measure of arc ABC
110 °
Answer:
Arc ABC = 250°
Step-by-step explanation:
m<AOB = 110° (given)
Based on the central angle theorem, central angle m<AOB equals the intercepted arc AB
Therefore,
m<AOB = measure of arc AB = 110°
Thus:
Arc ABC = 360° - arc AB (Full circle = 360°)
Arc ABC = 360° - 110°
Arc ABC = 250°
A company rents out 18 food booths and 27 game booths at the county fair. The fee for a food booth is $50 plus $6 per day. The fee for a game booth is $65 plus $8 per day. The fair lasts for d days, and all the booths are rented for the entire time. Enter a simplified expression for the amount, in dollars, that the company is paid.
Answer:
$2655 + $324d
Step-by-step explanation:
total cost of a booth = fixed cost + (variable cost x number of days)
Fixed costs are costs that do not vary with output
Variable costs are costs that vary with production
cost of 18 food booths = 18(50 + 6d) = 900 + 108d
cost of 27 game booths = 27(65 + 8d) = 1755 + 216d
Add the total cost of the food and game booths together 900 + 1755 = 2655
108d + 216d = 324d

The dot plots compare the number of raffle tickets sold by boys and girls during a school fund-raiser. Which plot has an outlier?
Answer:
Girl's plot
Step-by-step explanation:
The exact question is as follows :
Given - The dot plots compare the number of raffle tickets sold by boys and girls during a school fund-raiser.
To find - Which plot has an outlier?
Proof -
The correct answer is - Girls
Reason -
Girls plot has an outlier because values way outside the majority of the data.
Definition of outlier -
A value that "lies outside" (is much smaller or larger than) most of the other values in a set of data.
Here in the Girl's plot we can see that, all the dots are close but there is one dot that is lies outside
But in Boy's plot all the dots are close to each other , no dot is lies outside to any other dots.
So,
The correct option is -
Girl's plot has an outlier.
