Answer:
The number series 1, 2, 3, 4, . . . . , 99, 100. Therefore, 5,050 is the sum of positive integers upto 100.
Step-by-step explanation:
The sum of the numbers 1-100 would be equal to the number of pairs (50) multiplied by the sum of each pair (101), or 50 x 101 = 5,050.
Y-2=7(X -4) what form of an equation is this? please and thank you <3
9514 1404 393
Answer:
linear equation in the point-slope form
Step-by-step explanation:
There are many forms an equation for a line may take. Some of the ones commonly seen are ...
ax +by = c . . . . standard form (a,b,c mutually prime integers; a>0)
y = mx + b . . . . slope-intercept form (m=slope; b=y-intercept)
y -k = m(x -h) . . . . point-slope form (m=slope, (h, k)=point)
__
and some additional ones I commonly use are ...
x/(x-intercept) +y/(y-intercept) = 1
y = m(x -h) +k . . . . variation of point-slope form (m=slope; (h, k)=point)
y = (y2 -y1)/(x2 -x1)(x -x1) +y1 . . . . two-point form (points (x1, y1) and (x2, y2))
bx -ay = bh-ak . . . . line perpendicular to standard form line ax +by = c through point (h, k)
__
If you compare these forms to the equation you're given, you see it matches the "point-slope form" for point (4, 2) and slope 7.

Answer:
its b
Step-by-step explanation:
I scored 32 more points in my second unit test and I did it on my first my total points for both test were 164 what did I score on my two test
a = 66 points (first test)
b = 98 (second test)
Step-by-step explanation:Hi there !
a = first test
b = second test
a + b = 164
b = a + 32
replace b
a + (a + 32) = 164
2a = 164 - 32
2a = 132
a = 132 ; 2
a = 66 points (first test)
b = 66 + 32
b = 98 (second test)
Good luck !

The actual volumes of quart-size jars of Hellmann's mayonnaise are uniformly distributed from 31.58 to 32.51 fluid ounces. Find the standard deviation in volumes of quart-size Hellmann's mayonnaise jars (in fluid ounces). NOTE: There are 32 fluid ounces in a quart.
Answer:
0.27
Step-by-step explanation:
The standard deviation of a uniform distribution is:
σ² = (b − a)² / 12
σ² = (32.51 − 31.58)² / 12
σ² = 0.0721
σ = 0.268
Rounded to the hundredths place, the standard deviation is 0.27.
To solve this question, we use concepts of the uniform probability distribution.
Using this, we get that the standard deviation in volumes of quart-size Hellmann's mayonnaise jars is of 0.2685 fluid ounces.
Uniform probability distribution:
An uniform distribution has two bounds, a and b.
The standard deviation is:
[tex]S = \sqrt{\frac{(b-a)^2}{12}}[/tex]
The actual volumes of quart-size jars of Hellmann's mayonnaise are uniformly distributed from 31.58 to 32.51 fluid ounces.
This means that [tex]a = 31.58, b = 32.51[/tex]
Find the standard deviation in volumes of quart-size Hellmann's mayonnaise jars (in fluid ounces).
[tex]S = \sqrt{\frac{(32.51 - 31.58)^2}{12}} = 0.2685[/tex]
Thus, the standard deviation is of 0.2685 fluid ounces.

A coal company wants to determine a 95% confidence interval estimate for the average daily tonnage of coal that it mines. Assuming the company reports that the standard deviation of daily output is 200 tons, how many days should it sample so that the margin of error will be 39.2 tons or less?
Answer:
It should be 100 days sample so that the margin of error will be 39.2 tons or less
Step-by-step explanation:
We are given that A coal company wants to determine a 95% confidence interval estimate for the average daily tonnage of coal that it mines.
[tex]\alpha = 0.05[/tex]
To Find two tailed critical value using Z table
[tex]Z_{\frac{\alpha}{2}}=Z_{\frac{0.05}{2}}=\pm 1.96[/tex]
Margin of error = ME = 39.2
[tex]\sigma = 200[/tex]
Formula : [tex]n = (\frac{Z_{\frac{\alpha}{2}} \times \sigma}{ME})^2[/tex]
[tex]n = (\frac{1.96 \times 200}{39.2})^2[/tex]
n=100
Hence it should be 100 days sample so that the margin of error will be 39.2 tons or less
if the perimeter of a tennis court is 228 feet and the length is 6 feet longer than twice the width, then what are the length and the width?
Answer:
228-12 = 6w +12 -12
216 = 6w
divide both sides by 6
216/6 =6w/6
36 = w
so width = 36 feet
then the length is ..
l = 2w + 6
= 2*36 +6
= 72 +6=78
so the length = 78 feet
