You are gathering data in the classroom, recording the height that a ball bounces. The data you gather is A) bivariate B) catego
spin [16.1K]

Answer:

D) quantitative

Step-by-step explanation:

Bivariate data are two sets of items that are dependent to each other.

For example, coffee sales compared to the weather on a particular day.

Categorical data a collection of data representing quantities such as age, sex, educational level, blood group etc. It is a collection of data with different categories.

Discrete data can take only integer values.

For example, output of rolling a die is a number from 1 to 6.

Quantitative data are information that are measured and written with numbers.

Here, the height of a bouncing ball is measured and recorded.

Hence, the data we gather here is quantitative.

Consider the parent graph f(x) = x2 . Then, g(x) is a translation according the rule: y = (x + 3)2 + 4. Find the graph g(x).
krok68 [10]
For this case we have the following parent function:
 f (x) = x ^ 2
 We apply the following function transformation:
 Horizontal translations
 Suppose that h> 0
 To graph y = f (x + h), move the graph of h units to the left.
 We have then:
 y = (x + 3) ^ 2
 Vertical translations
 Suppose that k> 0
 To graph y = f (x) + k, move the graph of k units up.
 We have then:
 y = (x + 3) ^ 2 + 4
 Answer:
 
The graph g (x) is the graph f (x) 3 units to the left and 4 units up:
 
y = (x + 3) ^ 2 + 4

Ellis is painting wooden fenceposts before putting them in his yard. They are each 5 feet tall and have a diameter of 1 foot. Th
maksim [4K]

Answer:

Step-by-step explanation:

Comment

The first step is to find the surface area of 1 fence post.

The formula is

Area_ends = 2 pi r^2 for the ends.

Area_body = 2*pi*r * h

Givens

r = d/2          r is the radius ; d is the diameter

r = 1/2 foot

h = 10 feet

Solution

1 fence post

Area = ends + area body

Area =  2*3.14 * (1/2)^2 + 2 * pi * r * h

Area = 2*3.14* (1/2)^2 + 2 * 3.14 * 1/2 * 10

Area = 1.57 + 31.4

Area = 32,97 square feet.

10 fence posts

10*32.97 = 329.7 square feet

Answer

10 fence posts have 329.7 square feet in area.

sveta [45]

Answer:

Test statistic = - 2.33

Pvalue = 0.010 (3 decimal places)

Step-by-step explanation:

Given :

H0: p = 0.25 vs Ha: p < 0.25

Phat = 0.15

Sample size, n = 102

α = 0.05

The test statistic :

(Phat - p) / (√p(1 - p) /n)

1 - p = 1 - 0.25 = 0.75

(0.15 - 0.25) / (√0.25(0.75) /102)

-0.1 / √0.0018382

-0.1 / 0.0428742

Test statistic = - 2.33

The Pvalue using the test statistic score obtained :

P(Z < - 2.33) = 0.0099031 = 0.010

Pvalue < α ; Reject H0
