Answer:
x = 21/10
Step-by-step explanation:
3/10 = x/7
Cross multiply.
10x = 21
x = 21/10
Answer:
Option (C)
Step-by-step explanation:
From the given table,
Dependent variable is the weight of each load and independent variable is number of loads of crushed stones.
Let the equation that represents the total weight is,
W = mn + b
Where 'm' = slope of the line
b = y-intercept
n = number of loads
Since graph starts from the origin (0, 0), y - intercept 'b' will be 0.
Two points lying on the line are (0, 0) and (1, 2000)
Slope of the line 'm' = 
= 
=2000
Therefore, equation will be,
W = 2000n
Option (C) will be the answer.
Answer:
The function
is continuous for all real numbers
Step-by-step explanation:
To know the possible points of discontinuity of this function, we must find out when the denominator of the function is equal to 0.
The denominator is:

Then we equal 0 and clear x

for any real number.
This means that
<em>for all reals numbers</em>.
Therefore, the function
is <em>continuous</em> for all real numbers, that is, it does not have discontinuities.
The graphic of this function is shown in the image
Given:
<span>howler monkey: {15, 16, 17, 17, 17, 17, 18, 19}
</span><span>spider monkey: {12, 13, 13, 14, 14, 14, 16, 16}
The mean of the first set (howler monkey) = (15 + 16 + 17 + 17 + 17 +17 + 18 + 19)/ 8
The sum of all weights is divided by the number of monkeys weighed (n = 8)
mean = 17
Do the same for the second set (spider monkey) = 12+ 13 + 13+ 14 + 14+ 14 +14 +16 + 16 / 8
mean = 15.75
The ratio of the two is 17:15.75 or 1.08 is to 1. </span>
