<h2>
The required "option A) 20" is correct.</h2>
Step-by-step explanation:
Let x be the smaller than 4 ×
.
To find, the number of times smaller is 2 × 
than 4 × = ?
∴ x = 
= 2 × × 
Using the identity,
= 2 × 
Using the identity,
= 2 × 
= 2 × 10
= 20
Thus, the required "option A) 20" is correct.
Answer:
slope = 35; y-intercept = -45
Step-by-step explanation:
Function f(x) is written in the slope-intercept form, y = mx + b.
f(x) = -7x + 9
You compare it with
f(x) = mx + b, and you see that m, the slope, is -7, and b, the y-intercept is 9.
Now we deal with function h(x).
h(x) = -5(-7x + 9)
This is not written in the y = mx + b form, but we can put it in that form by distributing the -5.
h(x) = 35x - 45
Now, h(x) is written in the y = mx + b form. We see clearly that m = 35, so the slope of function h is 35. We also see that b, the y-intercept is -45.
Answer: slope = 35; y-intercept = -45
Answer:
-21.5
Step-by-step explanation:
-12-6=-18 minus 3.5=-21.5
The following list gives the number of public libraries in each of 11 cities. 7, 11, 8, 7, 8, 7, 8, 11, 8, 10, 7 Find the modes
AlladinOne [14]
Answer:
The mode are: 7, 8
Step-by-step explanation:
Given
Required
Determine the mode
We start by arranging the given data in ascending order
The ordered data are:
From the above data.
7 has a frequency of 4
8 has a frequency of 4
10 has a frequency of 1
11 has a frequency of 2
The data with the highest frequency is the mode.
We can see that 7 and 8 both have frequencies of 4
<em>Hence, the mode are: 7, 8</em>
10book=30mins
divide 10
1book=3mins
time=(time to read 1 book) times (number of books)
time to read 1 book=3 mins
15 books
15 books=15 times 3mins
15books=45mins
45 mins
