Answer:
$4.40
Step-by-step explanation:
you do 24=5x-2 so first you do 24-2 and u get 22 so then divide that by 5 since they each pay 5. then u end up with 4 dollars and 40 cents
1. The probability of telesales representative making a sale on a customer call is 0.15.
Representatives are required to achieve a mean of at least 5 sales each day.
(C) Find the least number oftcalls each day a representative should make to achieve this
requirement
(d) Calculate the least number of calls that need to be made by a representative for the
probability of at least 1 sale to exceed 0.95
Answer:
1c
[tex]n = 33[/tex]
1d
[tex]n = 19[/tex]
Step-by-step explanation:
From the question we are told that
The probability of telesales representative making a sale on a customer call is [tex]p = 0.15[/tex]
The mean is [tex]\mu = 5[/tex]
Generally the distribution of sales call made by a telesales representative follows a binomial distribution
i.e
[tex]X \~ \ \ \ B(n , p)[/tex]
and the probability distribution function for binomial distribution is
[tex]P(X = x) = ^{n}C_x * p^x * (1- p)^{n-x}[/tex]
Here C stands for combination hence we are going to be making use of the combination function in our calculators
Generally the mean is mathematically represented as
[tex]\mu = n* p[/tex]
=> [tex]5= n * 0.15[/tex]
=> [tex]n = 33[/tex]
Generally the least number of calls that need to be made by a representative for the probability of at least 1 sale to exceed 0.95 is mathematically represented as
[tex]P( X \ge 1) = 1 - P( X < 1 ) > 0.95[/tex]
=> [tex]P( X \ge 1) = 1 - P( X =0 ) > 0.95[/tex]
=> [tex]P( X \ge 1) = 1 - [ ^{n}C_0 * (0.15 )^0 * (1- 0.15)^{n-0}] > 0.95[/tex]
=> [tex] 1 - [1 * 1* (0.85)^{n}] > 0.95[/tex]
=> [tex] [(0.85)^{n}] > 0.05[/tex]
taking natural log of both sides
[tex]n = \frac{ln(0.05)}{ln(0.85)}[/tex]
=> [tex]n = 19[/tex]

Which statement correctly describes the expression (-60)(-5)? A. Both factors are negative, so the product will be positive. B. Both factors are negative, so the product will be negative. O C. One factor is positive and one factor is negative, so the product will be negative. D. One factor is positive and one factor is negative, so the product will be positive. SUOMI
Answer:
a
Step-by-step explanation:
Answer:
A. Both factors are negative, so the product will be positive
Step-by-step explanation:
Remember negative times negative will always be positive
And use the process of elimination:
You know that negative times negative is not negative so that eliminates B.
And there are two negatives in the equation not one positive and one negative so it is not choice C.
The same concept applies is for choice D.

Facundo crochets and sells baby blankets, b. Each blanket requires 3 skeins of yarn, and the total number of skeins Facundo uses, y, varies
directly as the number of blankets he crochets, b.
Write an equation that models this relationship.
Answer: y = 3b
Step-by-step explanation:
Equation of given relationship model is y = 3b.
What is equation?Equation is the defined as mathematical statements that have a minimum of two terms containing variables or numbers is equal.
Given,
∵ each blanket requires 3 skeins of yarn
∴ b blanket requires 3b skeins of yarn
Total number of skeins = y = 3b
Hence, y = 3b

Step-by-step explanation:
Hehe Hope it helped yu.
The reflection across the x-axis is an illustration of transformation, and the coordinates of the transformed point is (-4,-5)
How to determine the coordinates of the transformed point?The point is given as:
Point = (-4,5)
The rule of reflection across the x-axis is:
(x,y) -> (x,-y)
So, we have:
(x,y) -> (-4,-5)
Hence, the coordinates of the transformed point is (-4,-5)

1. Find 0.08% of 720.
Answer:
0.576
Step-by-step explanation:
First, you would change the percent to a decimal which is 0.0008
Second, you would multiply that by 720 (0.0008 x 720)
Third you would find your answer by calculating it, which is 0.576.
Another way
0.0008/ 100 × a/720 ≡ 0.576
The value of 0.08% of 720 is 0.576.
What is a percentage?The percentage is calculated by dividing the required value by the total value and multiplying by 100.
Example:
Required percentage value = a
total value = b
Percentage = a/b x 100
Example:
50% = 50/100 = 1/2
25% = 25/100 = 1/4
20% = 20/100 = 1/5
10% = 10/100 = 1/10
We have,
0.08% of 720
= 0.08/100 x 720
= 0.576
Thus,
0.576 is the value of 0.08% of 720.

Answer:
X = 30°, y = 15° and z = 150°.
Reason: Look below.
Step-by-step explanation:
Hey there!
When we look into the figure, we find that;
For x:
x+ 2x + 90° = 180° {Being linear pair}
or, 3x = 180°-90°
or, 3x = 90°
or, x= 90°/3
Therefore, X = 30°.
For y :
2y = x = 30° {Alternate angles are equal}
or, 2y = 30°
y = 30°/2
Therefore, y = 15°
For z:
2y + z = 180° { Being linear pair}
or, 30°+z = 180°
or, z = 180°-30°
or, z = 150°
Therefore, z = 150°.
