The table can be summarized as follows:
| | Has a dog | Does not have a dog |
|----------|-----------|---------------------|
| Has a cat | 2 | 3 |
| Does not have a cat | 12 | 10 |
To find the probability that a student chosen randomly from the class has a cat, we need to find the total number of students who have a cat (regardless of whether or not they have a dog), and divide it by the total number of students in the class.
The number of students who have a cat is 2 (those who have a dog and a cat) + 3 (those who have a cat but do not have a dog) = 5.
The total number of students in the class is the sum of all four categories: 2 (has a cat and a dog) + 3 (has a cat, does not have a dog) + 12 (does not have a cat, has a dog) + 10 (does not have a cat, does not have a dog) = 27.
So, the probability that a student chosen randomly from the class has a cat is 5/27.

Asaad invests $6800 in two different accounts. The first account paid 14 %, the second account paid 11 % in interest. At the end of the first year he had earned $856 in interest. How much was in each account?
Answers
Answer:
Step-by-step explanation:
Let x be the amount invested in the first account, which pays 14% interest. Then the amount invested in the second account, which pays 11% interest, is 6800 - x.
The interest earned on the first account is 0.14x, and the interest earned on the second account is 0.11(6800 - x). The total interest earned is the sum of these two amounts, so we have:
0.14x + 0.11(6800 - x) = 856
Simplifying and solving for x, we get:
0.14x + 748 - 0.11x = 856
0.03x = 108
x = 3600
Therefore, Asaad invested $3600 in the first account and $3200 (6800 - 3600) in the second account.
A painting contractor determined the average amount of time needed to paint a house. When 2 painters are used, it takes 15 hours to paint • When 6 painters are used, it takes 5 hours to paint. If p represents the number of painters and h represent the number of hours required to paint the house, which statement is true about this relationship?
Answers
The statement that is true about the proportional relationship is that; The time required to paint a house varies directly with the number of painters.
How to find proportional Relationship?The parameters are;
p represents the number of painters.
h represent the number of hours required to paint the house
In this case, the number of hours will be the output variable while the number of painters will be the input variable. Thus, we will have the relationship;
h = kp
where k is the constant of proportionality
When 2 painters are used, it takes 15 hours to paint and as such;
k = 15/2
k = 7.5 hours per painter
When 6 painters are used, it takes 5 hours to paint. Thus;
k = 5/6
k = 0.833 hours per painter
Thus, we can say that the time required to paint a house varies directly with the number of painters.

Using the distributive property, the expression is equivalent to
.
179% of 41 is about
Answers
The estimate of 179% of 41 by rounding is about 73.19.
To find this estimate, first convert the percentage to a decimal by dividing it by 100: 179/100 = 1.79. Then, multiply this decimal by 41: 1.79 * 41 = 73.39.
Since we are rounding, we round this value to the nearest whole number, which is 73. Therefore, the direct answer is 179% of 41 is about 73.When estimating by rounding, we look at the decimal places. In this case, the hundredth place is 3. Since 3 is less than 5, we round down. Hence, the estimate is 73.19. It is important to note that rounding introduces some degree of error, as the actual value is 73.39. However, for most practical purposes, an estimate provides a close approximation that is quick and easy to calculate.For more similar questions on whole number

Answers
The Simple Interest (SI) for a principal amount of $1000, a rate of interest of 3%, and a time period of 2 years is $60.
Using the formula for Simple Interest (SI):
SI = (P x r x t) / 100
where P is the principal amount, r is the rate of interest, and t is the time period in years.
Substituting the given values:
SI = (1000 x 3 x 2) / 100
SI = 60

Remember, the acceleration due to

Answers
The requried ball reached a maximum height of approximately 62 feet
Let the ball is thrown vertically upward, we can use the following formula to find the maximum height it reaches:
\(h(t) = -16t^2 + vt + h_0\)
here, h(t) is the height of the ball at time t, v is the initial velocity of the ball (in feet per second), and h0 is the initial height of the ball (in feet). We can also use the fact that the ball remains in the air for 3.8 seconds, which means that the time it takes to reach the maximum height is half of that or 1.9 seconds.
At the highest point, the ball's velocity is zero, so we can find the initial velocity by setting v = 0 in the above formula and solving for h₀:
h₀ = h(t) + 16t²
= 4 + 16(1.9)²
≈ 4 + 57.76
≈ 61.76
Therefore, the ball reached a maximum height of approximately 62 feet
