65 ÷ b + 8 x 4 = 20
Putting value of b = 5 in the equation
65 ÷ 5 + 8 x 4 = 20

13 + 32 = 20
45 = 20
Bringing like terms on one side
45 - 20 = 25

Step-by-step explanation:
Replace b for 45 in the equation
65/5+8x4=
According to the rules of PEMDAS (parentheses, exponents, multiplication, division (done in order they are given) addition and subtraction) You have to solve 65/5 first and then 8x4

Refer to the accompanying data set and use the 30 screw lengths to construct a frequency distribution. Begin with a lower class limit of 3.470 in., and use a class width of 0.010 in. The screws were labeled as having a length of 3 1/2 in
Answers
Answer:
Answer:
A) Total frequency = 30
B) Yes, the distribution is consistent with the label because the frequencies are greatest when the lengths are closest to the labeled size of 1/2 inches which is 0.5 inches.
Step-by-step explanation:
Since the class limit width is 0.010 from the question, we arrive at;
Class Limits Frequency
Length(Inches)
0.470 - 0.479 3
0.480 - 0. 489 5
0.490 - 0.499 9
0.500 - 0.509 12
0.510 - 0.519 1
Following is the frequency distribution table:
How to build a frequency table?The lower limit is given as 3.470 inches.
The upper limit is 3.500 inches.
And the width of each class is 0.010 inches.
Therefore, the intervals will be:
3.470-3.480
3.480-3.490
3.490-3.500

Line m passes through the point (1, 2) and has a slope of 2/5 What is the equation of line m in standard form?
Answers
Answer:
5y - 2x = 8
Step-by-step explanation:
First off we have to find the y-intercept with : b = y-mx
[tex]b=2-(\frac{2}{5})(1)[/tex]
[tex]b=\frac{10}{5}-\frac{2}{5}[/tex]
[tex]b=\frac{8}{5}[/tex]
now we have the point slope form
[tex]y=\frac{2}{5}x+\frac{8}{5}[/tex]
Multiply both sides by 5
[tex]5y=2x+8[/tex]
Subtract 2x from both sides
[tex]5y-2x=8[/tex]
