Answer:
a. 68
b. 128 moderates
c. The percentage of females in the sample
Step-by-step explanation:
Total high school student = 347.
There are 95 liberals of which 27 are males and 68 are females.
Of 128 Moderates, 91 are females and males are 37 in number
To find the total number of conservatives, we have:
Total no - (total moderates + total liberals) = total conservatives
347 - (128 + 95)
347 - 223
= 124 number of conservatives of which females are 93 and males are 31.
a. The joint frequency for liberal females is 68
b. And the largest marginal frequency for political preference is 128 moderates
c. what does the relative frequency 252/347 represent?
answer: total females: 68 + 91 + 93 = 252 out of 347 students. The percentage of females in the sample
Answer:
Check the answers in the tables below
Step-by-step explanation:
First I will explain the steps done in each column
Column 1: Multiply 2 numbers
Column 2: Split the terms inside the bracket in such a way that adding or subtracting those numbers we get the same number.
Column 3: Using distributive property a(b+c) = (ab)+(ac)
Column 4: Solving the expression by adding or subtracting the terms
1)
Given: Data in Column 2 100(0.04+0.06)
Column 1 Column 2 Column 3 Column 4 Value
100(0.1) 100(0.04+0.06) 100.0.04+100.0.06 4+6 10
2)
Given: Data in column 3 
Column 1 Column 2 Column 3 Column 4 Value
4+2 8
3)
Given: Data in Column 4 9+12
Column 1 Column 2 Column 3 Column 4 Value
3(7) 3(3+4) 3(3)+3(4) 9+12 21
4)
Given: Data in Column 4 24-16
Column 1 Column 2 Column 3 Column 4 Value
4(2) 4(6-4) 4.6-4.4 24-16 8
<span>An actor invested some money at 9% simple interest, and $42,000 more than three times the amount at 12% per annum. </span><span>What we are after is amounts of interest invested at 9% and at 12%. Let's call them x and y respectively.
x=42000 at 9% = </span>$3,780.00 = $45,780.00
y=3x42000 at 12% = $15,120.00 = $141,120.00
x+y=$186,900.00
Answer:
2/9
Step-by-step explanation:
lets create a sample space
so
the pirates can be sold for $7 $6 or $9
p
6 7 9
under the sea can be sold for $6 $7 or $9
S
6, 7, 9
driving test can be sold for $6 $7 or $9
D
6, 7, 9
here are all the combinations:
p,6
p,7
p,9
s,6
s,7
s,9
d,6
d,7
d,9
since out of 9 combinations driving test is the only one that is not water related lets look at that. There are only 2 combinations of driving test which are less than or equal to $7, (d,7 and d,6) hence the probability of selling no water games for less than $7 is 2/9
