To start we need to add all the pizzas to see how many total they made.

21+14+14+23=72

then the probablility that it is not a cheese pizza is the same as the probability that it is one of the other types

14+14+23=51

there is a 51/72 chance that the next pizza is not a cheeze pizza which equals 0.71 equaling a 71% chance

I hope I've helped!

The probability of the next pizza not being cheese is
P(not cheese) = 100 - P(cheese)

the probability of it being cheese is 21/(total)
Total = 21 + 14 + 23 + 14
Total = 72

So, P(cheese) = 21/72 x 100
which is roughly 29%

So P(not cheese) = 100 - 29 = 71%

Answer:

a) sample size is 40

Step-by-step explanation:

(a)

$\sigma=4$ minutes

Margin of error, E is 75 seconds E=75/60= 1.25 minutes.

The level of significance $\alpha= 0.05$ for 95% level of significance

For 95% confidence interval $z_{\frac{\alpha}{2}}=1.96$ from standard deviation table

Sample size required, n

$n=\left (\frac{z_{\frac{\alpha}{2}}\cdot \sigma}{E} \right )^{2}=\left (\frac{1.96\cdot4}{75/60} \right )^{2}=39.337984$

Rounding off, n=40

Sample size =40

Lake has a total of $10,000 to invest in two accounts. One account earns 1% simple interest, and the other earns 10% simple inte

Elza [17]

Answer:

$8000 at 1%
$2000 at 10%

Step-by-step explanation:

It often works well to let a variable represent the amount invested at the higher rate. Then an equation can be written relating amounts invested to the total interest earned.

<h3>setup</h3>

Let x represent the amount invested at 10%. Then 10000-x is the amount invested at 1%. The total interest earned is ...

0.10x +0.01(10000 -x) = 280

<h3>solution</h3>

Simplifying gives ...

0.09x +100 = 280

0.09x = 180 . . . . . . . subtract 100

x = 2000 . . . . . . divide by 0.09

10000 -x = 8000 . . . . amount invested at 1%

$8000 should be invested in the 1% account

$2000 should be invested in the 10% account
