each pizza has found out that each pizza has 12 slices. you expect 16 people to come, you estimate that each person will eat 3 s

konstantin123 [22]

Answer:

We will get 4 pizza.

Step-by-step explanation:

Each person will eat 3 slices of pizza and we are expecting 16 people to come.So total number of slices consumed by 16 people will be

16×3 = 48 slices.

Now it is given in the question that each pizza has 12 slices then we have to find out number of pizza to be ordered.

We apply unitary method

∵ 12 slices will be = 1 pizza

∴ 1 slice will be = 1/12 pizza

∴ 48 slices will be = 1/12×48

=48/12

= 4 pizza

So total 4 pizza to be ordered.

here a subtraction problem that has been solved incorrectly for 44-16=28 choose the addition sentence that check this subtractio

Vlad [161]

Answer:

Answer:

28+16=44

Step-by-step explanation:

point of correction it has been solved correctly

when subtracting 44 - 16 it gives you 28

=> 44 - 16

=> 28

SO IN ORDER TO CHECK IF THE PROBLEM WAS SOLVE CORRECTLY

you will minus 28 from one of the numbers before the equal sign

the correct option is 28 + 16 equals to 44

=> 28+16=44

.11 A machine produces metal pieces that are cylindrical in shape. A sample of pieces is taken, and the diameters are found to b

Troyanec [42]

Answer:

The 99% confidence interval for the mean diameter of pieces from this machine is between 0.93 and 1.07.

Step-by-step explanation:

Sample mean:

Sum of all values divided by the number of values. So

$M = \frac{1.01+0.97+1.03+1.04+0.99+0.98+0.99+1.01+1.03}{9} = 1$

Sample standard deviation:

Square root of the sum of the differences between each value and the mean, divided by the 1 less than the sample size. So

$s = \sqrt{\frac{(1.01-1)^2+(0.97-1)^2+(1.03-1)^2+(1.04-1)^2+(0.99-1)^2+(0.98-1)^2+(0.99-1)^2+(1.01-1)^2+(1.03-1)^2}{8}} = 0.0657$

Confidence interval:

We have the standard deviation for the sample, which means that the t-distribution is used to solve this question.

The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So

df = 9 - 1 = 8

99% confidence interval

Now, we have to find a value of T, which is found looking at the t table, with 8 degrees of freedom(y-axis) and a confidence level of $1 - \frac{1 - 0.99}{2} = 0.995$ . So we have T = 3.355

The margin of error is:

$M = T\frac{s}{\sqrt{n}} = 3.355\frac{0.0657}{\sqrt{9}} = 0.07$

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

The lower end of the interval is the sample mean subtracted by M. So it is 1 - 0.07 = 0.93

The upper end of the interval is the sample mean added to M. So it is 1 + 0.07 = 1.07

The 99% confidence interval for the mean diameter of pieces from this machine is between 0.93 and 1.07.

Guys i really need your help thanks friends. make sure to read carefully

Alexeev081 [22]

Answer:

$-\frac{39}{10}$

Step-by-step explanation:

$\frac{-\frac{1}{6}}{\frac{1}{9}} - \frac{12}{5}\\\\-\frac{1}{6}\cdot \frac{9}{1} - \frac{12}{5}\\\\-\frac{3}{2} - \frac{12}{5}\\\\-\frac{39}{10}$

Some things you have to keep in mind to solve this problem

$\frac{a}{\frac{b}{c}} = \frac{a}{b}\cdot \frac{1}{c}$

And also you have to know how to subtract fractions, if you don't please let me know and I'll try to give you a hand.

Good luck!
