Step-by-step explanation:
the length of a rectaangle 48 centimeters. The relationship between the length, the width, and the perimeter of the rectangle can be described with the equation 2x length +2w=48
find the length, in centimeters, if the if the width is:
10cm
3.6cm
w centimeters
Answer:
Step-by-step explanation:
We are told that the perimeter is 48 = 2L + 2W. This reduces to
24 = L + W. Next, substitute, one by one, the 3 widths 10 cm, 3.6 cm and w cm:
a) If W = 10 cm, 24 = L + W becomes 24 = L + 10, or L = 14 cm
b) If W = 3.6 cm, 24 = L + W becomes 24 = L + 3.6, or L = 20.6 cm
c) If W = w, 24 L + W becomes 24 = L + w, so that L = (24 - w) cm
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]
What is the value of the product (3 - 2i)(3+2i)?
Answer:
13
Step-by-step explanation:
1. Distribute each term in the first binomial to each term in the second binomial, FOIL (first, outer, inner, last)
(3 - 2i) (3 + 2i)
9 + 6i - 6i - [tex]4i^{2}[/tex]
2. Simplify
9 - [tex]4i^{2}[/tex]
3. Solve for i. [tex]i^{2}[/tex] = -1
9 - 4 (-1)
9 + 4 = 13

Mr Noris wrote a doubles fact. It has a sum greater than 6. The number that he added are each less than 6. What fact might he have written?
9514 1404 393
Answer:
4 + 4 = 8
5 + 5 = 10
Step-by-step explanation:
If we assume Mr Noris restricted himself to integer facts, we require both ...
2n > 6
n < 6
Dividing the first inequality by 2 gives ...
n > 3
Writing the two inequalities as a compound inequality, we have ...
3 < n < 6
There are two integers that satisfy this requirement:
n = 4 or n = 5
So, the doubles fact could have been either of ...
4 + 4 = 8
5 + 5 = 10

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°.
Hope it helps...

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.
