Answer:
Her final average now is 68.
Step-by-step explanation:
In order to find the grade average, you have to multiply each item for its percentage and add the results. Since the statement indicates that the final is 20% of the grade and she forgot to do it, that means that she got 0 for that 20%. Also, we can say that the average she has of 85 represents 80% of her grade and you have to multiply the average for the percentage:
85*0.8= 68
According to this, the answer is that her final average now is 68.
Find the IQR (interquartile range).
19, 21, 18, 17, 18, 22,46
Answer:
4.
Step-by-step explanation:
Step 1: Formula.
[tex]IQR=Q3-Q1[/tex]
--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Step 2: Explain/define.
The interquartile range is the difference between quartile 3 and quartile 1.Quartile 1 is the median of the upper half of a data set.Quartile 3 is the median of the lower half of a data set.The median is the 'middle value.'--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Step 3: Order/arrange.
In order to find the median, you must first put the numbers in numerical order.
19, 21, 18, 17, 18, 22, 46
↓
17, 18, 18, 19, 21, 22, 46
The lower half of the data set, not including the median of the whole data set, is 17, 18, and 18.
The upper half of the data set is 21, 22, and 46.
--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Step 4: Solve.
17, 18, 1821, 22, 36Next, we find the medians of both sets.
The median of the lower half is 18 (Q1).
The median of the upper half is 22 (Q3).
Lastly, we subtract Q3 from Q1.
[tex]22-18=4.[/tex]
--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Step 5: Conclude.
I, therefore, believe the interquartile range of this data set is 4.

There are 40 more pennies than nickels.
Find a combination that meets all 3 criteria:
*
There are 240 coins in the jar (only pennies, nickels, and
dimes)
* There are twice as many dimes as nickels.
* There are 40 more pennies than nickels.
*
Answer:
50 Nickels, 90 pennys, 100 dimes
Step-by-step explanation:
x = Nickels
x+40+x+x2=240
Add similar elements x+2x+x=4x
4x+40=240
Subtract 40 both sides
4x+40-40=240-40
4x =200
Divide Both sides by 4
4x/4 = 200/4
x=50

(08.03 MC) The dot plot below shows the hourly rate of some babysitters in a city: Which statement best describes the shape of the data? (1 point) Question 7 options: 1) It is symmetric and has no gaps. 2) It is not symmetric and has a peak at $5.00. 3) It is a cluster from $1.00 to $5.00 and has gaps. 4) It is a cluster from $1.00 to $5.00 and has a peak at $5.00.
Answer:
A. It is symmetric and has no gaps.
Step-by-step explanation:
Given
See attachment for dot plot
Required
Select the true statement
From the attached plot, we can see that
The plot is bell shaped (by tracing the number of dots on each dataset) There is no gap between each dataset (from 4 to 7)Since (1) all bell shaped distribution are symmetric and (2) there is no gap between the dataset, then (a) is correct.

(c) f(-2) = 3

(f) [tex]\lim_{x \to 1^-} f(x)=2[/tex]
(g) [tex]\lim_{x \to 1} f(x)=[/tex] DNE, because the limit of x--> 1 from the left is 2, and the limit from the right is 1. Because they don't approach the same value from both sides, the limit doesn't exist.
In 2002, the membership of a club totaled 5 thousand. By 2005, there were 29 thousand members of this club.
a. Write two ordered pairs of the form (x,y), where x is years after 2002 and y is membership in thousands.
b. Assume that the membership is linear between the years 2002 and 2005. Use the ordered pairs from part (a) to write an equation in slope-intercept form of the line
relating year and membership.
c. Use the linear equation from part (b) to predict membership in 2014.
Answer:
a)
(0, 5)
(3, 29)
b) y = 8x + 5
c) 101 thousand
Step-by-step explanation:
slope m = (29-5)/(3-0) = 24/3 = 8
y-intercept = (0, b) = (0, 5)
y = mx + b
y = 8x + 5
2014 - 2002 = 12
y = 8(12) +5
y = 96 + 5 = 101

The spinner is shown has eight congruent sides the spinner is spun 200 times. What is a reasonable prediction for the number of times the spinner will land on 2 or 3
Answer:
50 times
Step-by-step explanation:
Total number of faces = total possible outcomes = 8
Number of 2 or 3 on spinner = required outcome = 2
Probability of obtaining a 2 or 3 = required outcome / Total possible outcomes
P(2 or 3) = 2 / 8 = 1/ 4
From 200 ; prediction for the number of 2 or 3
1/4 * 200
= 50 times

16 girls and 14 boys put their names in a bag. One name is drawn from the bag. What is the probability that a boy's name will be pulled
Answer: [tex]\dfrac{7}{15}[/tex]
Step-by-step explanation:
Given
There are 16 girls and 14 boys
The favorable chances that a boy name comes up are 14
Probability is given by the ratio of favorable chances to the total chances
So, the probability that a boy's name will be pulled is
[tex]\Rightarrow P=\dfrac{14}{14+16}\\\\\Rightarrow P=\dfrac{14}{30}\\\\\Rightarrow P=\dfrac{7}{15}[/tex]

If (x,83) is a solution to the equation 2y=1/2(98x+38), find x.
Answer:
X= 2y/49 - 19/49
Answer:
because (x; 83) is a solution to the equation
2y=1/2(98x+38)
=> 2.83 = 1/2(98x + 38)
<=> 4.83 = 98x + 38
<=> 332 = 98x + 38
<=> 98x = 294
<=> x = 3
