Hello :
an equation in slope-intercept is : y=ax+b a is a slope

<span>18x – 4y = 5 .....
4y =18x- 5
y = (18/4)x -5/4

Based on a random sample of 25 units of product X, the average weight is 102 lbs., and the sample standard deviation is 10 lbs.

Alex

Answer:

Step-by-step explanation:

Given that for a sample size of 25, sample mean = 102 lbs. and sample std deviation = 10 lbs.

$H_0: \bar x = 100\\H_a: \bar x >100$

(Right tailed test)

Given that we assume population is normally distributed

Test statistic:

Mean difference = +2

Std error of sample = $\frac{10}{\sqrt{25} } =2$

t = test statistic = Mean diff/Std error $= 1$

degree of freedom $= n-1 =24$

Critical value of t = 1.711

Our test statistic >1.71

Accept alternate hypothesis

Because there is significant difference between the test statistic and test statistic lies above critical value.

By what percent will a fraction change if its numerator is decreased by 20% and its denominator is decreased by 60%?

Vedmedyk [2.9K]

Answer:

The fraction will increase by 100%

Step-by-step explanation:

Say the fraction is x/y. The question is telling us to decrease x by 20% (i.e. 0.8x) and to decrease y by 60% (i.e. 0.4y):

$= \frac{0.8x}{0.4y}\\= 2 (\frac {x}{y})$

You can see that by applying these changes, the new fraction is actually double the old fraction (i.e. will increase by 100%).

as part of her shop class, Jules made the figure below out of pieces of wood. how much spave does the figure she made take up?

OlgaM077 [116]

I suppose you want to find the Volume of this Figure.

you can separate it into two rectangular prisms
one that is 6 by 9 by 24
and the other that is 6 by 9 by 30

you multiply the three numbers to get the volume of each rectangular prism.
6 * 9 * 24 = 1296
6 * 9 * 30 = 1620

then we add the two numbers we got to get the overall volume of the figure
1296 + 1620 = 2916

Therefore the Figure takes up 2916 cm^3 of space.

Terry runs a snowplowing business. Income from snowplowing is given by the function f(x) = 35.5x + 6, where f(x) is the income i

eduard

It's C they are just out of order for the years.

f(x)=35.5x+6
For each year your plug in the snow total for x and solve
2006 x=53 so 35.5(53)+6=1887.5
2007 x=42 so 35.5(42)+6=1497
2008 x=55 so 35.5(55)+6=1958.5
2009 x=63 so 35.5(63)+6=2242.5
2010 x=58 so 35.5(58)+6=2065
2011 x=47 so 35.5(47)+6=1674.5

Hope that helps.
