Ghella [55]3 years ago
4 0

Answer:

2

Step-by-step explanation:

The text translates to:

5x + 2 < 13

which simplifies to

x < 11/5

the greatest integer that does this is 10/5, a.k.a. 2

The tuft bind strength of a synthetic material used to make carpets is known to have a mean of 100 lb and standard deviation of
emmasim [6.3K]

Answer:

The null hypothesis is: H_{0}: \mu = 100

The alternative hypothesis is: H_{a}: \mu > 100

Step-by-step explanation:

At the null hypothesis, we test if the mean is equal to a certain value.

At the alternate hypothesis, we test if the mean is less than, more than, or different from the value tested at the null hypothesis.

The tuft bind strength of a synthetic material used to make carpets is known to have a mean of 100 lb and standard deviation of 20 lb.

This means that the null hypothesis is: H_{0}: \mu = 100

Could it be that the average tuft strength is above 100 lb?

The world above means that the appropriate alternative hypothesis is: H_{a}: \mu > 100

Gema has 4 <br> FT of wire how much wire does she need to wrap one meter of her garden?
Dmitry [639]

Answer:

3.28 feet

Step-by-step explanation:

One meter equals to 3.28 feet.

The question isn't exactly clear what Gema wants to use her wire for, because "wrap one meter" isn't correct.

You wrap something around something else...  and you can't wrap something around a meter.  You can wrap around a square meter by doing the perimeter... but then you'd need more than meter to do the perimeter of a square meter (the perimeter can be around 4 meters).

So, assuming she has a length of 1 meter to cover, she would need 3.28 feet.

This table gives a few (x,y) pairs of a line in the coordinate plane
blagie [28]

Answer:

The x-intercept of the line is the point (12,0)

Step-by-step explanation:

step 1

Find the slope of the lime

Take the points

(22,36) and (32,72)

The formula to calculate the slope between two points is equal to

m=\frac{y2-y1}{x2-x1}

substitute the values

m=\frac{72-36}{32-22}

m=\frac{36}{10}

m=3.6

step 2

Find the equation of the line in point slope form

y-y1=m(x-x1)

we have

m=3.6

point (22,36)

substitute

y-36=3.6(x-22)

step 3

Find the x-intercept

we know that

The x-intercept of a line is the value of x when the value of y is equal to zero

so

For y=0

substitute in the equation and solve for x

0-36=3.6(x-22)

0-36=3.6x-79.2

3.6x=79.2-36

3.6x=43.2

x=12

therefore

The x-intercept of the line is the point (12,0)
