Answer:
P'(C) = 0.98
Step-by-step explanation:
Given that,
P(C) = 0.02 (The probability of getting C)
We need to find the complement of P(C) i.e. P'(C).
We know that,
P(C)+P'(C)=1
P'(C) = 1-P(C)
= 1-0.02
= 0.98
So, the complement of P(C) is equal to 0.98.
Tim is a postman that works at a local post office. The basic postage is $1.25 and cover any letter that is lighter than 7.5 grams. For heavier letters, extra postage of $.087 is needed for every 10 grams over 7.5 grams.Can a letter that is 705100 grams be covered by the basic postage
Answer:
705/100 grams cann be covered by the basic postage
Step-by-step explanation:
Given
Basic Postage
[tex]Weight < 7.5g[/tex]
Heavy letters
[tex]Weight \ge 7.5g[/tex]
Required
Can [tex]705/100[/tex] be covered in basic postage?
We have:
[tex]Weight = 705/100\ g[/tex]
[tex]Weight = 7.05\ g[/tex]
By comparing the above with the range of basic postage ---- [tex]Weight < 7.5g[/tex]
We have:
[tex]7.05g < 7.5g[/tex]
Since the above inequality is true, then the letter can be covered

The daily stock price for International Business Machines (IBM) historically has followed an approximately normal distribution (when adjusting for inflation) with a mean of $143.311 and standard deviation of $3.9988 Approximately 38.34% of days IBM had a stock price greater than what dollar amount
Answer:
Greater than $144.49.
Step-by-step explanation:
Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.
Mean of $143.311 and standard deviation of $3.9988.
This means that [tex]\mu = 143.311, \sigma = 3.9988[/tex].
Approximately 38.34% of days IBM had a stock price greater than what dollar amount?
Greater than X when Z has a p-value of 1 - 0.3834 = 0.6166, so X when Z = 0.295.
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]0.295 = \frac{X - 143.311}{3.9988}[/tex]
[tex]X - 143.311 = 0.295*3.9988[/tex]
[tex]X = 144.49[/tex]
Greater than $144.49.

The capacity of a water tank is 1000 litres. If 7/10 parts of the tank is emptied, how many litres of water are left in the tank?
Answer:
300litres
Step-by-step explanation:
capacity of water tank=1000litres
7/10 parts of tank is emptied,
method 1so, to know the litres of water left in the tank has to be equal to 1000litres-emptied tank
let X to represent water left in the tank
X=1000litres-(7/10*1000litres)
X=1000litres-700litres
X=300litres
hence, litres of water left in the tank =300litres
method 2since, full tank is 10/10 and you know the emptied tank has 7/10. meaning the remaining part of water is
10/10-7/10
3/10 of the tank with water
therefore, 3/10*1000litres
300litres.

Figure : 1The value of an exterior angle is equal to the sum of values of two opposite interior angles.
That is :
[tex]40 \degree + 40\degree = 3x + 20\degree[/tex][tex]80\degree = 3x + 20\degree[/tex][tex]3x = 60\degree[/tex][tex]x = 20\degree[/tex]Therefore, value of x is 20°
And the measure of missing angle is :

Hence,
[tex]v + 71\degree = 107\degree[/tex][tex]v = 36\degree[/tex]And therefore measure of missing angle is 36°, since v was the missing angle here.

The vertices of a rectangle in the coordinate plane are located at (4, -3), (4,5), (-5,5), and (-5, -3).
A bookmark is shaped like a rectangle with a semicircle attached at both ends. The rectangle is 17 cm
long and 4 cm wide. The diameter of each circle is the width of the rectangle. What is the area of the
bookmark? Use 3.14 for it.
The area of the bookmark is
cm?
Answer:
80.56
Step-by-step explanation:
To find the rectangle area you just multiply its length by its width:
17 * 4 = 68
You have to sum two semicircles on top of that. Since it is 2 semicircles you can just calculate one circle. Using the circle area formula: [tex]\pi*r^2[/tex]
Since the radius (r) is 2 and [tex]\pi[/tex] is 3.14, you have the following equation:
A = 3.14 * 2² ==> A = 3.14 * 4 ==> A = 12.56 (A is Area)
Sum the rectangle's area with the circle's area:
12.56 + 68 = 80.56

Solve the inequality below
6x - 5 < 55
Answer: x < 10
Step-by-step explanation: Just like any of your two-step equations, in this inequality, start by isolating the x term which in this case is 6x by adding 5 to both sides.
That leaves you with 6x < 60 and now just divide both sides by 2 and x < 10.
Notice that because we divide both sides of the inequality
by a positive number, not a negative, we did not change the
direction of the inequality sign.
Finally, put your answer in set notation, {x: x < 10}.
Unlike an equation which normally has one solution, the answer to an inequality must be stated as a solution set because an entire set of answers will work. In this problem, it's any number less than 10.

While remodeling their living room, the Smart family decided to repaint the walls. They
estimated that they could repaint 55 square feet every half-hour. How many square feet
can they paint per hour?
Answer:
The Smart family could paint 110 square feet per hour.
Step-by-step explanation:
Given that while remodeling their living room, the Smart family decided to repaint the walls, and they estimated that they could repaint 55 square feet every half-hour, to determine how many square feet can they paint per hour the following calculation must be performed:
1/2 = 0.5
0.5 = 55
1 = X
55 / 0.5 = X
110 = X
Therefore, the Smart family could paint 110 square feet per hour.

Suppose y varies jointly as x and z. Find y when x=9 and z=-3, if y=-50 when z is 5 and x is -10.
Answer:
y = -27 when x = 9 and z = -3
Step-by-step explanation:
y = kxz is the joint variation where k is a constant
Substitute the knowns in to find k
-50 = k( -10)(5)
-50 = -50k
k = 1
y = xz
Now find y
y = 9*-3
y = -27 when x = 9 and z = -3
28)A regression equation is obtained for a collection of paired data. It is found that the total variation is 24.488, the explained variation is 15.405, and the unexplained variation is 9.083. Find the coefficient of determination.
Answer: The coefficient of determination = 0.6291
Step-by-step explanation:
Given: Total variation is 24.488, the explained variation is 15.405, and the unexplained variation is 9.083.
The coefficient of determination is computed as:
[tex]\text{ coefficient of determination} =\frac{\text{explained variation }}{\text{total variation}}[/tex]
Substituting given values, we get
[tex]\text{coefficient of determination} =\frac{15.405}{24.488}[/tex]
[tex]=0.6291[/tex]
Therefore, the coefficient of determination = 0.6291
Lori downloaded all the pictures she took at Rita’s wedding into a single computer folder. She took 86 of the 134 pictures with her camera and the remainder of them with her cell phone. Of the pictures Lori took with her cell phone, one out of every five was blurry.
To the nearest whole percent, what is the probability that when she opens a random picture from the computer folder, it will be a blurry picture she took with her cell phone?
7%
13%
31%
56%
The probability that when she opens a random picture from the computer folder, it will be a blurry picture she took with her cell phone is 7%.
Probability is the likelihood or tendency that something will occur.
Probablility of blurry picture=(134-86)×0.2/134
Probablility of blurry picture=48×0.2/134
Probablility of blurry picture=9.6/134×100
Probablility of blurry picture=7.16
Probablility of blurry picture=7% (Approximately)
Thus, the probability that when she opens a random picture from the computer folder, it will be a blurry picture she took with her cell phone is 7%.

Step-by-step explanation:
Explanation for Number 7.
The exterior angle is always equl to the sum of the two opposite interior angles.
The two opposite interior angles: 62 and (7x + 14)
The exterior angle: (15x - 4)
So you would set it up like _____ = ______ to solve for x
62 + (7x +14) = 15x - 4
62 + 7x + 14 = 15x - 4
Then move the terms
76 + 7x = 15x - 4
Collect the like terms and Calculate
7x - 15x = -4 - 76
