Of 100 random student surveyed, 42 own a dog, 33 own a cat, and 16 own a dog and cat, and 9 own neigher a dog or cat. Based upon the results, how many of the next 150 students surveryed would you expect to own a dog and cat?

Answer:

The correct answer is C. 126 units².

Step-by-step explanation:

To solve this problem, we must first realize that this figure is a trapezoid. To find the area of a trapezoid, we should use the following formula:

Area = 1/2(b1 + b2)*h

In this formula, b1 and b2 represent the two bases of the trapezoid and h represents the height.

The height of the trapezoid is 9 units, and the bases are 16 units and 12 units.

Plugging in these values, we get:

A = 1/2(16 units + 12 units)(9 units)

A = (1/2)(28 units)(9 units)

A = 14 units * 9 units

A = 126 units²

Therefore, the correct answer is C. 126 units².

Step-by-step explanation:

this triangular prism can be divided into 3 rectangles(S = a*b) and 2 right angle triangles((a*b)/2)

so, the surface area of the triangular prism = ( 4*2 + 3*2 + 5*2) + ((4*3)/2 + (4*3)/2) = 2(1/2 * 3 * 4) + 4 * 2 + 3 * 2 + 5 * 2

Step-by-step explanation:

the product of Janelle's score and 3 is 39, using the variable J to represent Janelle's score.

which can be expressed mathematically as

[tex]j \times 3 = 39[/tex]

cause product is the same as multiplication ✖️

[tex]3j = 39[/tex]

finally, divide both sides by 3

[tex] \frac{3j}{3} = \frac{39}{3} [/tex]

therefore

[tex]j = 13[/tex]

Answer:

13

Step-by-step explanation:

j x 3= 39

so then you use the fraction thingy

[tex]\frac{3j}{3}= \frac{39}{3}[/tex]

so then its 39 divided by 3 gets 13

so its 13

Answer:

One pattern that can be observed in the repeated table is that each number is obtained by adding 0.09 to the previous number.

Step-by-step explanation:

For example, to get from 0.09 to 0.18, we add 0.09. To get from 0.18 to 0.27, we add 0.09 again, and so on. This pattern continues throughout the table, with each number being 0.09 greater than the previous number.

Part A - In the given table we can observe that there is a continuous table of 0.09 till 0.63.

Part B - The table is in the ‘Step by step explanation’

Step-by-step explanation:

The total number of candies in the jar is 70, out of which 14 are brown. Therefore, the number of candies that are not brown is 70 - 14 = 56.

To find the probability of drawing a candy that is not brown, replacing it, and then drawing an orange candy, we can use the multiplication rule of probability. According to this rule, the probability of two independent events occurring together is the product of their individual probabilities.

So, the probability of drawing a candy that is not brown on the first draw is 56/70. After replacing the candy, there are still 70 candies in the jar, so the probability of drawing an orange candy on the second draw is 28/70.

Multiplying these probabilities, we get:

(56/70) x (28/70) = 0.16

Therefore, the probability of randomly drawing a candy that is not brown, replacing it, and then drawing an orange candy is 0.16 or 16%.

The statement that is best supported by the information shown on the dot plots is A. The data of the two populations have different ranges.

The range of the data as shown in the dot plots of the weight of squirrels in the two populations can be found by the formula :

= Largest weight - Smallest weight

Range of population 1;

= 18 - 12

= 6 ounces

Range of population 2:

= 19 - 11

= 8 ounces

The range of the two populations is therefore different.

Answer:

Step-by-step explanation:

a^(-x) = 1/(pi^(1/x)) in fractional form.

1/a^x = 1/pi

Next, we can rewrite a^(-x) as 1/a^x and substitute the expression for 1/a^x from the above equation:

a^(-x) = 1/a^x = 1/(pi^(1/x))

The value of [tex]a^{-x}[/tex] when [tex]a^x = \pi \ is\ 1/\pi[/tex]. To find the value of [tex]a^{-x}[/tex] when [tex]a^x = \pi[/tex], we can use the properties of exponents.

First, recall that a^(-x) is the reciprocal of [tex]a^x[/tex]. In other words, [tex]a^{-x} = 1 / a^x[/tex].

Given that [tex]a^x = \pi[/tex], we have:

[tex]a^{-x} = 1 / a^x\\a^{-x} = 1 / \pi[/tex]

So, The value of [tex]a^{-x}[/tex] when [tex]a^x = \pi \ is\ 1/\pi[/tex].

Answer:

X= 4,469

Y=4,474

Z=4,478

Step-by-step explanation:

X = 4469

Y = 4474

Z = 4478

X = 4470 - 1 = 4469   OR   4480 - 11 = 4469

Because, X is 1 space behind 4470 and 11 spaces behind 4480.

Y = 4470 + 4 = 4474   OR   4480 - 6 = 4474

Because, Y is 4 spaces ahead of 4470 and 6 spaces behind 4480.

Z = 4470 + 8 = 4478   OR   4480 - 2 = 4478

Because, Z is 8 spaces ahead of 4470 and 2 spaces behind 4480.
