Show solution of the ratio of 14 days to 3 weeks in simplest form?

Mathematics

Paladinen [302]3 years ago

Answer:

2:3

Step-by-step explanation:

We are asked to find the ratio 14 days to 3 weeks in simplest form.

We know that 1 week equals 7 days, so 3 weeks will be equal to 21 (3*7) days.

So our ratio would be 14:21.

We can see that 14 and 21 share a common factor 7.

14:21=7\cdot2:7\cdot3=2:3

Therefore, our required ratio would be 2:3.

14:3 can be written as 14/3...and this does not simplify

A TV has a listed price of $579.95 before tax. If the sales tax rate is 7.75%, find the total cost of the TV with sales tax incl
kkurt [141]

To find the sales tax multiply the purchase price by the sales tax rate. Remember to convert the sales tax rate from a percent to a decimal number. Once the sales tax is calculated, it is added to the purchase price. The result is the total cost—this is what the customer pays.

CCA has stated in 2017 that 36.5 % of its students are first generation college students.Suppose you sample 15 CCA students and
nignag [31]

Answer:

Step-by-step explanation:

The formula for binomial distribution is expressed as

P(x = r) = nCr × p^r × q^(n - r)

Where

x represent the number of successes.

p represents the probability of success.

q = (1 - p) represents the probability of failure.

n represents the number of trials or sample.

From the information given,

p = 36.5% = 36.5/100 = 0.365

q = 1 - p = 1 - 0.365

q = 0.635

n = 15

a) P(x = 0) = 15C0 × 0.365^0 × 0.635^(15 - 0) = 0.0011

P(x = 1) = 15C1 × 0.365^1 × 0.635^(15 - 1) = 0.0095

P(x = 2) = 15C2 × 0.365^2 × 0.635^(15 - 2) = 0.038

P(x = 3) = 15C3 × 0.365^3 × 0.635^(15 - 3) = 0.095

P(x = 4) = 15C4 × 0.365^4 × 0.635^(15 - 4) = 0.16

P(x = 5) = 15C5 × 0.365^5 × 0.635^(15 - 5) = 0.21

k P(X = k)

0 0.0011

1 0.0095

2 0.038

3 0.095

4 0.16

5 0.21

b) mean = np = 15 × 0.365 = 5.475

c) standard deviation = √npq

= √15 × 0.365 × 0.635

= 1.86

d) z = (x - mean)/standard deviation

x = 2

z = (2 - 5.475)/1.86 = - 1.87

How to get the x intercept<br> y=(2x+3)(x-1)(x-4)
Papessa [141]
Well, to get the x intercept you have to substitute 0 for y and solve for x, and get rid of the parenthesis ( y=2x+3*x-1*x-4 ) unless you want three different x-intercepts. So if you do want those three intercepts, leave the parenthesis.
