Answer:
Your answer is 1050 cards are from after the 2000s.
Step-by-step explanation:
25% of the cards are before 2000, so that means 75% of 1400 cards are after the 2000s.
.75*1400 = 1050
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

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

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. 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°

In ⊙C, DE ≅ FG, Which statement must be true? Select all that apply.
Answer:
E because is covered all angle
< DCE ≅ < GCF must be true
Hence Option A and E are true statements.
What are angles of circle?A circle has a total of 360 degrees all the way around the center, so if that central angle determining a sector has an angle measure of 60 degrees, then the sector takes up 60/360 or 1/6, of the degrees all the way around. In that case, the sector has 1/6 the area of the whole circle.
According to the given figure:
DE ≅ FG
So < DCE ≅ < GCF must be true
Because DE ≅ FG
< DCE ≅ <GCF is similar to DE ≅ FG
Hence, < DCE ≅ < GCF must be true
Hence Option A and E are true statements.

if the probability of rain tomorrow is 0.15 what is the probability that it will not rain
Answer:
85% or 99.85%
Step-by-step explanation:
If you mean 15% by 0.15 then the probability that it will not rain is 85% because, 100-15=85.
If you mean 0.15% by 0.15 then the probability that it will not rain is 99.85% because, 100-0.15 is 99.85.
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
Writing a linear equations
Answer:
y = 1/2 x - 2
Step-by-step explanation:
The standard linear equationof a line is expressed as y = mx+b
Using the coordinate points (0, -2) and (2, -1)
Slope m = -1-(-2)/2-0
m = -1+2/2
m = 1/2
Since the line cuts the y axis sat y = -2, hence the intercept b = -2
Get the required equation;
Recall that y = mx+b
y = 1/2 x + (-2)
y = 1/2 x - 2
This give the required linear equation
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.

Answer:
5/8 - 1/4
Step-by-step explanation:
because it makes more sense I don't know how to explain
Answer:
4th option.
Step-by-step explanation:
The number getting subtracted is 5/8 since there are 5 boxes shaded in.
The number subtracting from it is 2/8 but that is not an option so the only other option equivalent to 2/8 is 1/4.
5/8 - 1/4 = 3/8 so the answer would also need to include 3/8 as the difference.
The only choice with all this is the 4th one
