Since she can speak more than 7, you can mentally get rid of A and B because the circles on the number line show less than or equal to and more than or equal to, and we already know she can speak more than 7 languages.
So between the less than or greater than symbol you need to pick the line that has the arrow pointing in the direction of the greater than symbol because she can speak more than 7 languages
The answer would be C because greater than symbols point in the same direction of the line >

Consider random samples of size 80 drawn from population A with proportion 0.48 and random samples of size 66 drawn from population B with proportion 0.13 . (a) Find the standard error of the distribution of differences in sample proportions, . Round your answer for the standard error to three decimal places. standard error
Answers
Answer:
Standard error = 0.070
Step-by-step explanation:
Formula for the standard error of the distribution of differences in sample proportions is;
σ_(A - B) = √((p_a^(1 - p_a^)/n_a) + (p_b^(1 - p_b^)/n_b))
We are given;
p_a^ = 0.48
n_a = 80
p_b^ = 0.13
n_b = 66
Thus;
σ_(A - B) = √((0.48(1 - 0.48)/80) + (0.14(1 - 0.13)/66))
σ_(A - B) = √0.00496545455
σ_(A - B) = 0.070

An account earns simple annual interest.
$1500 at 4% for 5 years
Answers
Answer:
a) Interest earned = $300
b) balance = $1800
Step-by-step explanation:
a) I = Prt
P = $1500
r = 0.04
t = 5yrs
Substitute
I = ($1500)(0.04)(5)
Multiply
I = $300
b) balance = previous + interest earned
balance = $1500 + $300 = $1800
The account amounts to $1800 at 4% simple interest for 5 years.
What is simple interest?We know simple interest (SI) is given by SI = (p×r×t)/100, where
p = principle, r = rate in percentage, and t = time in years.
Given, An account earns simple annual interest $1500 at 4% for 5 years.
∴ P = $1500, r = 4%, t = 5 years.
So, SI = (1500×4×5)/100.
SI = 15×20.
SI = $300.
So, The total amount after 5 years at 4% simple interest is $(1500+300).
= $1800.

Five plumbers charge different hourly
rates: $35, $42, $52, $38, and $42.
Find the mean, median, mode, MAD,
and IQR of these values. Which
measure of center and which measure
of variability best describe the data?
Answers
Explanation: for mean you add all the numbers up and divide it based upon how much numbers there are in total, so for this problem it would be:
$35 + $42 + $52 + $38 + 42 ÷ 5 = 41.8
**The median is: $42**
Explanation: to find the median we arrange the numbers from least to greatest or greatest to least you’ll get the same answer for median.
Original: $*35, $*42, $52, $*38, $*42
Least to greatest: ($35, $38, $42, $42, $52)
Greatest to least: $52, $42, $42, $38, $35)
Then we find the number in the center which is: $42 for the median.
**The mode is: $42**
Explanation: To find the mode we just see what number was repeated the most which in this case is $42
**MAD (Mean Absolute Deviation) is: $4.24**
Explanation to find the MAD we need to first add all the numbers up and divide them by the number of elements there are in the data set in total.
So we do,
$35 + $42 + $52 + $38 + 42 ÷ 5 = 41.8
Just as we did for finding the mean the difference for this though is after we’ve found this number we subtract each number by 41.8
and when we subtract the rule is there is no negative numbers so if any you subtract turn out to be negative you change it to positive so it would be:
$35 - $41.8 = (-6.8) change to + = 6.8
$42 - $41.8 = 0.2
$52 - $41.8 = 10.2
$38 - $41.8 = (-3.8) change to + = 3.8
$42 - $41.8 = 0.2
Then we add all the numbers up we just got and divide it by the number of elements in the date set so we do, $6.8 + $0.2 + $10.2 + $3.8 + $0.2 = 21.2 ÷ 5 = $4.24
**IQR (Interquartile Range) is: $10.5**
Explanation to find the IQR we order the numbers least to greatest or greatest to least it doesn’t matter which order you do it.
Greatest to least: $52, $42, $42, $38, $35
Least to greatest: $35, $38, $42, $42, $52
Q1 is: $36.5
Explanation: we get this by adding:
$35 + $38 ÷ 2 = 36.5
Q2 is: $42
Explanation: it’s right in the center
Q3 is: $47
Explanation: we get this by adding:
$42 + $52 ÷ 2 = $47
In order to find IQR we need to do Q3 - Q1
So, $47 - $36.5 = $10.5
**Measure of the center: (Mean = $41.8, Median = $42, Mode = $42, Range = $17**
Explanation: for range we simply subtract the biggest number from the smallest one which would be $52 - $35 = $17
**Measure of variability: (range = $42, Standard deviation = $2.91, Variance = $8.48)**
Explanation for standard of deviation we first find the mean which is $41.8, then we subtract each number be $41.8 which will give us these numbers which we’ll multiple by 2:
$6.8 x 2 = $13.6
$0.2 x 2 = $0.4
$10.2 x2 = $20.4
$3.8 x 2 = $7.6
$0.2 x 2 = $0.4
Then the numbers you get you add up and divide it by the number of elements in the data, which would be $13.6 + $0.4 + $20.4 + $7.6 + $0.4 = 42.4 ÷ 5 = 8.48
So the variance is: $8.48
Then to find the standard deviation we square root $8.48 which gives us: $2.91

A cylinder has a base radius of 8ft and a height of 17ft. What is its volume in cubic ft, to the nearest tenths place?
Answers
Answer:
Step-by-step explanation:
Volume = πr²h = π·8²·17 = 1088π ≅ 3,418.1 ft³
Since this cylinder has a radius of 8 feet, its volume is equal to 3,418.5 cubic feet.
Given the following data:
Radius of cylinder = 8 feet.
Height of cylinder = 17 feet.
How to calculate the volume?Mathematically, the volume of a cylinder is given by this formula:
V = πr²h
Where:
h is the height.r is the radius.Substituting the given parameters into the formula, we have;
V = 3.142 × 8² × 17
V = 3.142 × 64 × 17
V = 3,418.5 cubic ft.
