Enny’s mother is 5 years older than twice Jenny's age. The sum of their ages is 62 years. This is represented by the equation x
pickupchik [31]
X + 2x + 5 = 62 which can be turned into.
3x + 5 = 62 
      -5      -5 now we subtract 5 from each side
3x = 57
/3     /3 now we divide 3 from each side to get...
x = 19.
Now to check 19 + (2 x 19) + 5 does in fact equal 62.  Jenny is 19 years old.  Hope this helped.

Construct a 99% confidence interval for the population standard deviation of white blood cell count (in cells per microliter). A
kogti [31]

Answer:

The correct option is 1.148 < σ < 6.015

Explanation:

The 99% confidence interval for the standard deviation is given below:

\sqrt{\frac{(n-1)s^{2}}{\chi^{2}_{\frac{0.01}{2} }} }

Where:

\chi^{2}_{\frac{0.01}{2} }=18.548

\chi^{2}_{1-\frac{0.01}{2}}=0.676

Therefore, the 99% confidence interval is:

\sqrt{\frac{(7-1)2.019^{2}}{18.548} }

1.148

Therefore, the option 1.148 < σ < 6.015 is correct

Karl makes 7 1/2 batches of cookies using 1 1/2 dozen eggs. Suppose Karl only
vredina [299]

Answer:

5\ batches\ of\ cookies

Step-by-step explanation:

we know that

Karl makes 7 1/2 batches of cookies using 1 1/2 dozen eggs

so using proportion

Find out how many batches of cookies could he make with a dozen eggs

step 1

Convert mixed numbers to an improper fraction

7\frac{1}{2}=\frac{7*2+1}{2}=\frac{15}{2}

1\frac{1}{2}=\frac{1*2+1}{2}=\frac{3}{2}

step 2

Applying proportion

Let

x ----> the amount of batches of cookies

\frac{(15/2)}{(3/2)}\frac{batches}{dozen\ eggs}=\frac{x}{1}\frac{batches}{dozen\ eggs}\\\\x=\frac{15}{3}\\\\x=5\ batches\ of\ cookies
