Z is directly proportional to x, that means :
z = k.x, with k is the coefficient of proportionality:
Let calculate k:
When x = 5, z = 55. Plug in:
55 = k.5 → k=55/5 ; k =11
The value of z when = 12 is : z= kx; z = 11(12) and z = 132
First you multiply the last term by the first term (3h+16h+15). Then find numbers that add to 16 and multiply to 15 then add or subtract it from (3h+15)(3h+1). Then factor if possible (h+5)(3h+1)
Answer:
9 grams
Step-by-step explanation:
<u>We can use these equations</u>:
y = ax
- Where y is the total amount of baking soda (in mg)
- Where a is the number of servings
- Where x is the amount of baking soda in one single serving (in mg)
Here we know that y = 1800 and a = 2, so we will need to solve for x
- Solving for x we get
and plugging in our known values we get
and this simplifies to 900 - This means one serving contains 900 mg of baking soda
We can now change the equation to solve for the total amount of baking soda required to serve 10 people
- We know that a = 10 and x = 900
- The equation is already solved for y, so plugging in our new values we have y = (10)(900) = 9000 mg
- The recipe will require 9000 mg in order to serve 10 people
Now there are 1000 mg in 1 g, so converting mg to g we have 9000 mg is equivalent to 9 grams
Answer:
The 80% confidence interval for the mean consumption of meat among people over age 23 is between 4 and 4.2 pounds.
Step-by-step explanation:
We have that to find our
level, that is the subtraction of 1 by the confidence interval divided by 2. So:

Now, we have to find z in the Ztable as such z has a pvalue of
.
So it is z with a pvalue of
, so 
Now, find M as such

In which
is the standard deviation of the population and n is the size of the sample.

The lower end of the interval is the mean subtracted by M. So it is 4.1 - 0.07 = 4.03 pounds
The upper end of the interval is the mean added to M. So it is 4.1 + 0.07 = 4.17 pounds
Rounded to one decimal place
The 80% confidence interval for the mean consumption of meat among people over age 23 is between 4 and 4.2 pounds.
