Amanda [17]

According to the number of cups, 564 people can be invited to the party.

Step-by-step explanation:

This is a simple question of cross multiplication

DATA:

1. Total number of cups of yogurt is 423 cups

2. 1 serving = $\frac{3}{4}$ th of a cup

3. Each guest gets $\frac{3}{4}$ of a cup or 1 serving

4. Find out how many guests can be invited to the party,

Cups : People

$\frac{3}{4}$ : 1

423 : p

5. Cross multiply

$\frac{3}{4}$ p = 423 x 1

3p = 423 x 4

p = $\frac{1692}{3}$

p = 564

Therefore, according to the number of cups, 564 people can be invited to the party.

vladimir2022 [97]

Answer:

Step-by-step explanation:

a). Mean of the given data set = $\frac{32+28+18+40+22}{5}$

= 28

b). x $x-\overline{x}$ $(x-\overline{x})^2$

32 32-28 = 4 16

28 28 - 28 = 0 0

18 18 - 28 = -10 100

40 40 - 28 = 12 144

22 22 - 28 = -6 36

$\sum({x-\overline x})^2$ = 296

c). Standard deviation = $\sqrt{\frac{\sum (x-\overline{x})^2}{n}}$

= $\sqrt{\frac{296}{5} }$

= 7.69

d). Mean of the new set of weights = $\frac{32+33+34+35+36}{5}$

= 34

Since mean of the data set is more close to each data, standard deviation will be less than the deviation given in part (c).

What is the value of a in the equation 5a -10b = 45 when b = 3

leva [86]

Salutations!

$5a-10b = 45$

value of $b = 3$

Multiply 10 and 3

$10*3=30$

Now, you can solve the equation --

$5a-30=45$

separate the variables aside, and the numbers aside.

$5a=45 +30$

$5a=75$

$a=75/5$

$a=15$

Hope I helped (:

Have a great day!
