If the probability of a cup drink being rasberry flavour is 0.29, what is the probability of a cup drink being cola flavour?

Answers

Answer: 0.71

Step-by-step explanation:

Since we have just two flavors, the probability of a cup drink being cola flavour will be calculated below:

P(R) + P(C) = 1

0.29 + P(C) = 1

P(C) = 1 - 0.29

P(C) = 0.71

Therefore, the probability of a cup drink being cola flavour is 0.71.

Dexter deposits $200 in a bank account that earns 3% simple intrest.How much money will he have in the account after 1 year

Answers

Answer:

$206

Step-by-step explanation:

The amount that would be in the account = amount deposited + interest earned on deposit

interest earned on deposit can be determined by determining the simple interest

Simple interest = principal x time x interest rate

principal = the amount deposited = $200

Time = the duration of the deposit = 1 year

interest rate = the percentage on deposit that would be earned = 3%

200 x 0.03 x 1 = $6

The amount that would be in the account = $200 + $6 = $206

A local pizza shop has a membership program for frequent buyers. The membership
costs $20 per month and members get a discounted price of $2 per slice of pizza.
Wyatt purchased a membership to this pizza shop. How much would Wyatt have to
pay the pizza shop if he bought 14 slices of pizza this month? What would be the
monthly cost for x slices of pizza?

Answers

Answer: $48.

Step-by-step explanation:

Since each slice of pizza is $2 and Wyatt bought 14 slices of pizza, you would multiply 14 by 2 then add it onto the cost of the membership.

14 * 2 = 28

20 + 28 = 48

The monthly cost for 14 slices of pizza is $48.

x will equal 40.

EXPLANATION: since they’re parallel and these are opposite angles, add them together to equal 180.
x+(20)+3x=180.
add common variables.

subtract 29 from both sides
4x=160

A rectangle has a length of 24cm and breadth is 6cm.Express the breadth as a percentage of the length

Answers

Answer:

Breadth is 25% of the length

Step-by-step explanation:

Length, l = 24 cm

Breadth, b = 6cm

Expressing the breadth as a percentage of the length :

(Breadth / length) * 100%

(6 / 24) * 100%

0.25 * 100%

= 25%

Hence, the breadth is 25% of the length
