The answer would be 16.

you have to multiply 4 and 8 which =32 and then divide 32 by 2 which =16

4*8=32 four boxes of 8 cookies equals 32 cookies total
32/2=16 32 cookies divided by 2 per child

16 kids can be served

Compute a 99% confidence interval for the mean weight of toxic substance per gram of mold culture. State the assumption you make

kow [346]

Complete Question

The complete question is shown on the first uploaded image

Answer:

The 99% confidence interval is $2.4309 < \mu < 4.9328$

Step-by-step explanation:

From the question we are told that

The data is 3, 2,5, 3, 2, 6, 5,4.5, 3, 3, and 4

The sample size is n = 11

Generally the sample mean is mathematically represented as

$\= x = \frac{\sum x_i}{n}$

=> $\= x = \frac{3+ 2+5+ \cdots +4 }{11}$

=> $\= x = 3.6818$

Generally the sample standard deviation is mathematically represented as

$\sigma = \sqrt{\frac{\sum [ x_i - \= x ] }{n} }$

=> $\sigma = \sqrt{\frac{[ 3 - 3.6818 ]^2 +[ 2 - 3.6818 ]^2 + \cdots + [ 4 - 3.6818 ]^2 }{11} }$

=> $\sigma = 1.3091$

Given that the confidence interval is 99% then the level of significance is mathematically represented as

$\alpha= (100 - 99) \%$

=> $\alpha= 0.01$

Given that the sample size is small we will making use of t distribution table

Generally from the t distribution table the critical value of at a degree of freedom of is

$t_{\frac{\alpha }{2} , 10 } =3.16927267$

Generally the margin of error is mathematically represented as

$E = 3.16927267 * \frac{1.3091 }{\sqrt{11} }$

$E = 1.251$

Generally 99% confidence interval is mathematically represented as

$3.6818 -1.251 < p < 3.6818 + 1.251$

=> $2.4309 < \mu < 4.9328$

i need to know how to find the x and y intercepts and then graph the linear equation for the problem x+y=2

gizmo_the_mogwai [7]

Answer:

The x-intercept of the straight line is at (2,0) and the y-intercept is at (0,2).

Join those two points with a straight line and get the graph.

Step-by-step explanation:

The intercept form of a straight line equation is $\frac{x}{a} + \frac{y}{b} = 1$ , where the x-intercept of the line is at (a,0) and the y-intercept will be at (0,b).

So, we have to arrange the equation of a straight line in the intercept form and then we can easily find the x-intercept and y-intercept of the line.

Given equation is x + y = 2

⇒ $\frac{x}{2} + \frac{y}{2} = 1$

Therefore, the x-intercept of the straight line is at (2,0) and the y-intercept is at (0,2).

Now, locate the two points as obtained on the graph and join them with a straight line and you will get the graph of the line. (Answer)

amid [387]

Answer:

Step-by-step explanation:

3x/y=x/2y

Since 2y is 2X greater than y, 6x is 2X greater than 3x.

So,

The answer is 6x.

A father of 12 at death orders his lawyer to share his properties amongest his 12 sons. if the man is worth 12.3 million, and ea

GuDViN [60]

Answer:

Step-by-step explanation:

The man has twelve sons. So we need an equation that has twelve numbers added to 12.3 million. The youngest son's share is what we want to find, so set it to x. Each son older will have 175 more than the one younger than him.

So the next to youngest will have x+175(1) and the next will have x+175(2) and so on to the twelfth one.

So....

x + x+175 + x+175(2) + x+175(3) + x+175(4) + x+175(5) + x+175(6) + x+175(7) + x+175(8) + x+175(9) + x+175(10) + x+175(11) = 12,300,000

Now simplify. Add all the x's and multiply all the numbers.

12x + 350+525+700+875+1050+1225+1400+1575+1750+1925+2100=12,300,000

Continue to simplify by adding.

12x+13,475=12,300,000 Now simplify by subtracting the non 'x' number from both sides

12x+13,475-13,475=12,300,000-13,475

12x=12,286,525 Now simplify by dividing both sides by 12.

x = 1,023,877.08

The youngest son will inherit 1,023,877.08.

There should be a unit:$, pounds, something.
