Answer:
16 minutes
Step-by-step explanation:
Given
Represent minutes with M and Phone calls with P.
When M = 8; P = 2
Required
Determine M when P = 4
First, we need to determine the constant of proportion using:
[tex]M = k * P[/tex]
Where k represents the constant:
[tex]8 = k * 2[/tex]
Divide through by 2
[tex]4 = k[/tex]
[tex]k = 4[/tex]
Solving for M, when P = 4
Substitute 4 for P and 4 for k in [tex]M = k * P[/tex]
[tex]M = 4 * 4[/tex]
[tex]M = 16[/tex]
Hence:
She spent 16 minutes in total

Ten students in your class put their names on slips of paper inside a box. Out of the ten students, four are girls, and six are boys. Five names are chosen.
What is the probability that three girls and two boys are chosen?
1.90%
350%
7.14%
23.81%
Answer:
23.81%
Step-by-step explanation:
The total number of ways to select 5 out of 10 will be;
10 C 5 = 252
The number of ways of selecting 2 boys out of 6 will be
6 C 2 = 15 ways
The number of ways of selecting 3 girls out of 4 will be
4 C 3 = 4 ways
The probability of both will be;
(4 * 15)/252 = 60/252 = 0.238095238095
To the nearest percentage, that will be 23.81%

6 blue slabs have a mean weight of 7 kg. 3 yellow slabs have a mean weight of 5 kg. 1 grey slab has a mean weight of 9kg. work out the mean of 10 slabs
Answer: 6.6kg
Step-by-step explanation:
6 blue slabs have a mean weight of 7 kg. The total weight of the 6 blue slabs will be:
= 6 × 7kg
= 42 kg
3 yellow slabs have a mean weight of 5 kg. The total weight of the 3 yellow slabs will be:
= 3 × 5kg
= 15kg
1 grey slab has a mean weight of 9kg.
To get the mean of the 10 slabs, we add their total weights together and divide by 10. This will be:
= (42kg + 15kg + 9kg)/10
= 66kg/10
= 6.6kg
Based on the information given the mean of 10 slabs is 6.6 kg.
Formulate
(9+5×3+6×7)/10
Calculate the quotient
9+15+6×7/10
9+15+42/10
Calculate the sum or difference
24+42/10
66/10
Reduce the fraction
33/5
Hence:
Mean=6.6 kg
Inconclusion the mean of 10 slabs is 6.6 kg.

1. Identify each of the following situations or equations as proportional or non-proportional and explain your reasoning.
(a) The total cost of rent is determined by recording x months of rent at $1400 per month, plus a $150
application fee.
(b) y =3/4x
(c) y=1/2x - 6
Answer:
a. Non proportional
b. Proportional
c. Non proportional
Step-by-step explanation:
Here, we want to determine if each situation is proportional or not
a) Non-proportional
This is because the amount y paid in a month will be;
y = 1400x + 150
Since the amount paid is not solely dependent on the number of months, then we do not have a proportional relationship
b) proportional
y = 3/4x
The value of y is dependent solely on that of x, so the relationship is proportional
c) non proportional
Since the value of y is not solely entirely dependent on x value, then the relationship is not proportional
Diane earns $14,500 a year. She pays 11% of her gross income for federal, state, and local taxes. She is taxed at the FICA rate of 7.65%. She has 3.5% of her income withheld for personal deductions. She is paid biweekly. What is her net pay for each pay period? Round to nearest cent.
Answer:
$434.16346
Step-by-step explanation:
Given that :
Gross earning= $14500
Federal, state and local taxes = 11%
0.11 * $14500 = $1595
FICA tax rate = 7.65%
0.0765 * 14500 = $1109.25
Personal deduction :
3.5% * 14500
0.035 * 14500 = $507.50
Total deduction :
$(1595 + 1109.25 + 507.50)
= $3211.75
Net earning : $(14500 - 3211.75) = 11288.25
Since she is paid bi weekly:
Number of biweeks in a year = 52 /2 = 26
Number of payments per annum = 26
Hence,
Net pay per period :
11288.25 / 26
= $434.16346
