Step-by-step explanation:
4) 35° and x° are vertical angles, so they are congruent to each other. Therefore, x°=35°. Since y°+y°+35°=180° since they are all supplementary to each other, then y°=72.5° when solved.
5) A is true. Think of two adjacent angles measured 60° and 30° that are next to each other. They add up to 90° as well.
B isn't true. Vertical angles are congruent to each other, not supplementary.
C isn't true. The statement contradicts itself. Complementary angles add up to 90° while supplementary angles add up to 180°
What is the probability of rolling a 20-sided number cube to a number that is prime or a multiple of 3?
Answer:
Probability of rolling a prime or multiple of 3 = 13/20
Probability of rolling a prime = 2/5
Probability of rolling a multiple of 3 = 3/10
Step-by-step explanation:
let's list primes and multiples of 3 from 1 to 20
Primes:
2 3 5 7 11 13 17 19
Multiples of 3:
3 6 9 12 15 18
Primes OR multiples of 3
2 3 5 6 7 9 11 12 13 15 17 18 19
There's 13 of them, so the probability of rolling a prime or multiple of 3 is 13/20
Probability of rolling a multiple of 3 is 6/20 = 3/10
Probability of rolling a prime is 8/20 = 2/5
Answer:
0.6 or [tex]\frac{12}{20}[/tex] or [tex]\frac{3}{5}[/tex]
Step-by-step explanation:
Here are the multiples of 3 (that are 20 or below) :

what is the area of the white box
Answer:
12 m²Step-by-step explanation:
The white box is a rectangle with width of:
a = 2 m
and length of:
b = 7 m - 1 m = 6 m
So its area is A = 2 m × 6 m = 12 m²
{The shaded blue area is: (5 m + 1 m)(8 m) - 12 m² = 48 m² - 12 m² = 36 m²}
Abigail and Grace collected clovers. Abigail collected clovers with
4 leafs and Grace collected clovers with 5 leafs. They counted the
number of leafs in both collections and realized that it is the
same. What is the least number of leafs that each collection must
have?
Answer:
20
Step-by-step explanation:
To find the least number of leafs that each collection must have, we find the L.C.M of both numbers. So L.C.M of 4 and 5.
The prime factors of 4 = 2²
The prime factors of 5 = 5
So L.C.M of 4 and 5 = 2² × 5 = 20
So, the least number of leafs that each collection can have is 20 leafs.

the volume of a cube is 710 cm cubed work out the length of its side rounded to one decimal place
Answer:
8.9cm
Step-by-step explanation:
Volume of a cube = L × L × L = L³
710 = L³
L = ³√710
L= 8.9 cm
The length of each side of Cube is 8.9 cm.
What is Volume of Cube?The length is to be multiplied by itself three times to get the volume. The volume is measured in cubic units.
For example, cubic units.
Given:
Volume of a cube is 710 cm.
So, Volume of Cube = l³
710 = l³
l = ∛710
l = ∛ (71 x 10
l = 8.9 cm
Hence, the edge length is 8.9 cm.

Answer:
3x = 14
Step-by-step explanation:
Add the two equations.
5x + (-2x) = 3x
(-y) + y = 0
6 + 8 = 14
3x = 14.
Step-by-step explanation:
5x - y = 6 and -2x + y = 8
1/ 5x - y = 6
=> y = 5x - 6
2/ -2x + y = 8
Substitute 1/ into 2/ we will have:
-2x + (5x - 6) = 8
=> -2x + 5x - 6 = 8
=> 3x = 14
=> x = [tex]\frac{14}{3}[/tex] <=> y = [tex]\frac{52}{3}[/tex]
- However, the question asked for the final equation when adding 5x - y = 6 and -2x + y = 8 => The correct answer will be: 3x = 14
Investigators conducting a study regarding the effects of water pollution and peptic ulcer disease obtained the following data: A population of 9000 men and women, aged 45, were examined on January 1, 1985. Of these people, 6000 were exposed to toxins in the local water supply and 3000 were not. At the time of this exam, 90 cases of peptic ulcer disease were discovered; 60 of these cases were among those exposed to toxins in their local water. All the people at the initial exam who were free from peptic ulcer disease were followed with repeat exams over the following year. This study revealed 268 new cases in the total group; of these, 238 cases were among those exposed to toxins in their local water. A. Calculate the prevalence per 1000 people of peptic ulcer disease on January 1, 1986: Among the exposed Among the unexposed B. Calculate the 1985 incidence rate/1000 people of peptic ulcer disease: Among the exposed Among the non exposed
Answer:
Kindly check explanation
Step-by-step explanation:
The prevalence per 1000 among the exposed :
Total number of diseases among those exposed = 60 + 238 = 298
Prevalence per 1000 among the exposed :
(298 / 9000) * 1000 = 33.11
Prevalence per 1000 among the non exposed :
((90 - 60) + (268 - 238)) / 3000
(60 / 3000) * 1000 = 20
Incidence rate per 1000 among the exposed :
238 / 5940 * 1000
0.0400673 * 1000 = 40.07
Incidence rate per 1000 among the unexposed :
((90 - 30) / (3000-30)) * 1000
(60/2970) * 1000 = 20.2

A restaurant owner wants feedback on the items on the menu, so she leaves a customer satisfaction survey on the tables for customers to
complete if they wish. Which sampling method best describes this scenario?
O A) convenience sample
OB) simple random sample
O C) stratified random sample
OD) voluntary response sample
Answer:
O A) convenience sample
Step-by-step explanation:
O A) convenience sample
The sampling method which describes the situation is option D. voluntary response sample.
What are Sampling Methods?Sampling methods are methods used to select a sample using specific methods. This includes various types of probability sampling and non probability sampling methods.
This is included in the non probability sampling methods.
So it is either convenience sample or voluntary response sample.
Convenience sample is the selection of a sample which is convenient for you. That is, the sample which is most accessible is selected by the researcher.
Voluntary response sample is also the one which is most accessible. But the researcher is not selecting the sample. Instead the members of the population can decide whether to took part in the sample.
Here it is customer's wish to complete the survey.
So it is voluntary response sample.
Hence the correct option is D. voluntary response sample.
