Answer:
{0, 1, 2, 3, 4, 5,....} ;
{0, 1, 2, 3} ;
Step-by-step explanation:
Number of insect on a randomly selected plant
The number of insect in such an experiment will be an integer value ;
Hence, sample space will be ;
{0, 1, 2, 3, 4, 5,....}
B.) Event of at most three insects:
Number of insects = 0 ;
Number of insect = 1 ;
Number of insect = 2 ;
Number of insect = 3 ;
n ≤ 3 {x : x ≤ 3}
{0, 1, 2, 3}
3.)
Each possible outcome in the sample space cannot be equally likely due to the fact that the number of insects on the selected plants will vary. With some plants having none to large number of insects while some have small amount of insects.
The sum of 2 numbers is 30. Their product is 176. What are the 2 numbers?
Answer:
Step-by-step explanation:
x, 30 - x add to 30. The other condition says
x (30 - x) = 176. Multiply it out.
30x - x^2 = 176, so
x^2 - 30x = -176, complete square by adding 15^2 to both sides
(x - 15)^2 = 225 - 176 = 49, take square root
x - 15 = 7, so one number is:
x = 22 and the other is 30 - x = 8.
The price of a computer is reduced by 17.5%. The reduced price is £264 by how much is the price reduced
Answer:
Step-by-step explanation:
100%-17.5%= 82.5%
82.5% (divide) 82.5%= 1%
so (1% of the orginal price)=
£264 (divide) 82.5%= £320= original price
The price of the computer is reduced by £56 which is 17.5% of £320.
What is the percentage?A percentage is a value per hundredth. Percentages can be converted into decimals and fractions by dividing the percentage value by a hundred.
Given, The price of a computer is reduced by 17.5% and the reduced price is £264.
Let the original price be '£x'.
So, (100 - 17.5)% = 82.5% of '£x' is £264.
∴ (82.5/100)×x = 264.
0.825x = 264.
x = 264/0.825.
x = £320.
So, The price reduced is (320 - 264) = £56.

HELP ME PLZ!!!! A bakery sold 48 chocolate cupcakes in a day, which was 12% of the total number of cupcakes sold that day. How many total cupcakes did the bakery sell that day?
400 cupcakes will be sold by the bakery on that day if the percentage of total sales is 12%.
What is the percentage?It's the ratio of two integers stated as a fraction of a hundred parts. It is a metric for comparing two sets of data, and it is expressed as a percentage using the percent symbol.
A set of financial statements with a budgeted amount are created using the percentage-of-sales approach. The predicted sales level for the budget period is calculated by converting each historical cost into a percentage of net sales.
It is given that,
Total number of chocolate cupcakes sold = 48
Let the x be the cupcakes that will be sold by the bakery on that day
According to the given condition, 12% of the total number of cupcakes is 48.
⇒12% of x = 48
⇒(12/100) × x =48
⇒x=(48×100)/12
⇒x=400
Thus, 400 cupcakes will be sold by the bakery on that day if the percentage of total sales is 12%.

When Trudy planted a large bush in her garden, it was 2 feet tall. Now it is 50% taller. How tall is the bush now?
Answer: 3 feet tall
Step-by-step explanation:
50% of something is also 1/2 of it. So if we multiply 2 by 1/2 or .5, we get 1. So then we take 1 and add it to 2 because it is 50% taller than what it used to be.

Graham recruited student volunteers to participate in his dissertation study. He set up several times for students to come to a specified classroom and read various types of instructional materials and to be tested. He ran all of his control conditions first and then for each session he placed all students at the session in the same treatment condition. This is problematic because those who volunteered early are likely different than those who volunteered later. This problem is primarily due to 1. response bias. 2. instrumentation bias. 3. researcher bias. 4. sampling bias.
Answer:
Sampling bias
Step-by-step explanation:
Bias refers a prominent problem in statistical analysis whereby one or more analytical factor are favored than the other during an analysis which should be made random. The problem. With Graham's dissertation study is the fact that he failed to randomlyvplace his subjects or observation in the study groups, favoring a particular group with non random subset. When randomization is ejected or missing from an analysis or study, it becomes less and less representative. Here, allotting early Arrivals Into the treatment group has introduced a sampling bias as those who came later, this will also leads to less reproducibility of experiment.

Here are eight angles. Which of these angles are obtuse angles?
Enter your answer as a list of letters, separated by commas. For example, if you believe angles A, B, and F are obtuse, type A, B, F.
Help me please. Please, Please!!!
The obtuse angles from the given list are D (between 90° to 180°) and E (111° angle). Thus, the answer is D, E.
The angles are given as follows:
A: less than 45°
B: greater than 270°
C: right angle
D: between 90° to 180°
E: A 111° angle
F: A 222° angle
G: A 0.180° angle
H: A 180.180° angle
To identify which angles are obtuse, we need to determine the angles that are greater than 90 degrees but less than 180 degrees.
Among the given angles:
A: less than 45° (not obtuse)
B: greater than 270° (not obtuse)
C: right angle (not obtuse)
D: between 90° to 180° (obtuse)
E: 111° angle (obtuse)
F: 222° angle (not obtuse)
G: 0.180° angle (not obtuse)
H: 180.180° angle (not obtuse)
Therefore, the obtuse angles from the given list are:
D (between 90° to 180°)
E (111° angle)
The answer is D, E.

A statue of George Washington is also in Druids a 15 m away from the statue and places a mirror 12 m from the statue (3 m from her feet)she can see the top of the statue in the mirror. The girl's height is How tall is the statue(draw a diagram and solve)
Answer:

Let 'x' represent the height of the statue.
1 ft = 0.3048 m
5.5 ft = 5.5*0.3048 m
Using the similar triangles we can write:
x : 3 = 12 : (5.5*0.3048)
x = 21.47 m
The statue is 21.47 meters tall
