nekit [7.7K]

Answer:

Probability of people order a salad or an appetizer P(A∪B) = 62%

Step-by-step explanation:

Given:

Probability of appetizer P(A) = 55%

Probability of salad P(B) = 25%

Probability of choose both P(A∩B) = 18%

Find:

Probability of people order a salad or an appetizer P(A∪B)

Computation:

P(A∪B) = P(A) + P(B) - P(A∩B)

P(A∪B) = 55% + 25% - 18%

P(A∪B) = 62%

Probability of people order a salad or an appetizer P(A∪B) = 62%

MAXImum [283]

Answer:

3691 pounds

Step-by-step explanation:

Given: Colin invests £2350 into a savings account. The bank gives 4.2% compound interest for the first 4 years and 4.9% thereafter

To find: Amount that Colin will have after 10 years

Solution:

Let P, r, n denotes principal, rate of interest and time period

For the first 4 years:

$P=\£\,2350\,,\,r=4.2\%\,,\,n=4$

Total amount after 4 years = $P\left ( 1+\frac{r}{100} \right )^n=2350\left ( 1+\frac{4.2}{100} \right )^4=\£ 2770.38$

For the next 6 years:

$P=\£\,2770.38\,,\,r=4.9\%\,,\,n=6$

Total amount after 6 years = $P\left ( 1+\frac{r}{100} \right )^n=2770.38\left ( 1+\frac{4.9}{100} \right )^6=3691.41\approx \£\,3691$

Henry correctly subtracted 3p+5/3p from p+3/p-2 and got 12p^2+9p-3p^2+p+10/(p-2)(3p). What is the simplified difference?

IrinaK [193]

Answer:

Step-by-step explanation:

Henry subtracted ( 3p+5)/3p from ( $(\frac{p+3}{p-2})$ and got

$\frac{(12p^{2}+9p-3p^{2}+p+10}{(p-2)(3p)}$

We have simplify the difference

= $\frac{(12p^{2}+9p-3p^{2}+p+10}{(p-2)(3p)}$ = $\frac{(12p^{2}-3p^{2})+(9p+p)+10}{(p-2)(3p)}$

= $\frac{9p^{2}+10p+10}{(p-2)(3p)}$
