A lawn mower is pushed a distance of 100 ft. Along a horizontal path by a constant force of 60 lbs. Yhe handle of the lawn mower

stira [4]

For this case we have the following equation:
w = F • PQ
Where,
w: work done
F: is the force vector
PQ: is the vector of the direction of movement.
Rewriting the equation we have:
w = || F || • || PQ || costheta
Substituting values:
w = (60) * (100) * (cos (45))
w = (60) * (100) * (root (2) / 2)
w = 4242.640687 lb.ft
Answer:
The work done pushing the lawn mower is:
w = 4242.6 lb.ft

A new catalyst is being investigated for use in the production of a plastic chemical. Ten batches of the chemical are produced.

zzz [600]

Answer:

$CI=(66.54,78.46)$

Step-by-step explanation:

Given : A new catalyst is being investigated for use in the production of a plastic chemical. Ten batches of the chemical are produced. The mean yield of the 10 batches is 72.5% and the standard deviation is 5.8%. Assume the yields are independent and approximately normally distributed.

To find : A 99% confidence interval for the mean yield when the new catalyst is used ?

Solution :

Let X be the yield of the batches.

We have given, n=10 , $\bar{X}=72.5\%$ , s=5.8%

Since the size of the sample is small.

We will use the student's t statistic to construct a 995 confidence interval.

$\bar X\pm t_{n-1,\frac{\alpha}{2}}\frac{s}{\sqrt n}$

From the t-table with 9 degree of freedom for $\frac{\alpha}{2}=0.005$

$t_{n-1,\frac{\alpha}{2}}=t_{9,0.005}$

$t_{n-1,\frac{\alpha}{2}}=3.250$

The 99% confidence interval is given by,

$CI=72.5 \pm 3.25\frac{5.8}{\sqrt{10}}$

$CI=72.5 \pm 5.96$

$CI=(72.5+5.96),(72.5-5.96)$

$CI=(66.54,78.46)$

Please help me with this

Dvinal [7]

Answer:

a. E = {1, 2, 3, 4, 5, 6, 7, 8}
b. A ∩ B = {2, 3}
c. A ∪ B = {1, 2, 3, 4, 5, 7, 8}

Step-by-step explanation:

Locate the designated space on the diagram and list all the numbers in it.

a. E = {1, 2, 3, 4, 5, 6, 7, 8} . . . . all numbers in the rectangle

b. A ∩ B = {2, 3} . . . . where the circles overlap

c. A ∪ B = {1, 2, 3, 4, 5, 7, 8} . . . . only 6 is outside the circles

Scientists researching the effect of dietary supplements such as multivitamins and supplements of folic acid, magnesium or zinc

yarga [219]

Answer: Null hypothesis : $H_0: p_1=p_2$

Alternative hypothesis : $H_a: p_1\neq p_2$

Step-by-step explanation:

Let $p_1$ be the proportion of women using supplements and $p_2$ be the proportion of women who did not to have died during that period .

Then the set of hypothesis for testing if the proportion of women elderly women who use dietary supplements is different than those who do not will be :-

Null hypothesis : $H_0: p_1=p_2$ [∵ it takes equality sign]

Alternative hypothesis : $H_a: p_1\neq p_2$ [∵ it takes ≠ sign to show difference]
