What is the probability of rolling an even number on a number cube containing numbers 1 through 6? *

Answers

Answer 1

Answer:

[tex]\frac{1}{2}[/tex] or 50%

Step-by-step explanation:

Cube has 6 sides = 3 odds and 3 even

probability is found using

[tex]\frac{number of favourable outcomes}{number of total outcome}[/tex] which is [tex]\frac{3}{6} or \frac{1}{2}[/tex]

1/2 = 50%

divide 600 in the ratio 2: 3: 4​

Answers

Answer:

133.33, 200, 266.66

Step-by-step explanation:

GIven data

This is a ratio problem, and we will use the part to all method to get the solution

The given ratio is

= 2: 3: 4​

the total ratio

=2+3+4

=9

Hence the first part is

2/9= x/600

cross multiply

9x= 1200

x= 1200/9

x= 133.33

The second part

3/9=x/600

1/3=x/600

3x=600

x=200

The third part

4/9=x/600

4/9=x/600

9x=600*4

9x=2400

x=2400/9

x=266.66

Therefore the figures are

133.33, 200, 266.66

Sophia invested $79,000 in an account paying an interest rate of 6.8% compounded
continuously. Assuming no deposits or withdrawals are made, how long would it
take, to the nearest year, for the value of the account to reach $152,800?

Answers

Answer:

10

Step-by-step explanation:

The value of the account will reach $152,800 in 10 years.

What is Compound Interest?

Compound interest is defined as the amount of interest which has been calculated on the principal amount as well as the amount accumulated over the previous period is also included.

Interest compounded continuously means there is no limit for the process of compound of interest. It is compounding infinite times.

The formula for calculating the final amount when the interest is compounded continuously is,

A = P e^(r t)

Here, A is the final amount, P is the initial or principal amount, r is the rate of interest and t is the number of years.

Given that,

A = $152,800

P = $79,000

r = 6.8% = 6.8/100 = 0.068

We have to calculate t.

152,800 = 79,000 e^(0.068 t)

152,800 / 79000 = e^(0.068 t)

1.934 = e^(0.068 t)

Taking logarithms on both sides,

㏑ 1.934 = ㏑ e^(0.068 t)

We have ㏑(a)ⁿ = n ㏑(a)

0.65968 = 0.068t ㏑ e

0.65968 = 0.068 t × 1

t = 9.7 ≈ 10 years

Hence the amount is compounded to $152,800 in 10 years.

Answers

Answer:

0.59998

Step-by-step explanation:

Number of keys = 3

Number of coins = 7

Total = 10

Number of items taken out = 2

Expected number of keys taken out:

Let x = Number of keys taken out

X = 0

1st pick = 7/10

2nd pick = 6/9

7/10 * 6/9 = 0.46666

X = 1

(7/10 * 3/9) + (3/10 * 7/9) = 0.46666

X = 2

(3/10 * 2/9) = 0.066666

X : ____ 0 ______ 1 _______ 2

P(X): _0.46666__0.46666 _0.06666

Expected value :

Find the area of a triangle with a base of 10 inches and a height of 5 inches

Answers

Answer:

area = 25 in^2

Step-by-step explanation:

area = 1/2(10)(5) = 25 in^2

Answer:

The height is 4 inches.

For a triangle, we have Area = 1/2 base times height.

With a = area, b = base and h = height,

we have:

A=1/2bh

We are told that A=10 square inches and b=5 inches, so we need to solve (find h ) for:

10=1/2(5)h

We can get rid of the fraction by multiplying by 2 on both sides:

20=5h

Now divide noth sides by 5 (or multiply by 1/5 , to get

20/5=5h/5 so 4=h

The height is 4 inches.

Which of the following is an appropriate test for the investigation?

Answers

Answer:

B

Step-by-step explanation:

I don't know

An appropriate test for the investigation is, One sample t-test for sample mean. So option B is correct

What is a random sample ?

The process of selecting a sample of data from a population in order to draw conclusions about the population is known as random sampling. Additionally known as probability sampling. Non-probability sampling, often known as non-random sampling, is this sample's opposite. Simple random sampling, stratified sampling, cluster sampling, and multistage sampling are the main forms of this sampling. Convenience samples are often referred to as non-arbitrary samples in sampling methodologies.

Given that,

Population mean = $100

Sample = n = 56

Sample mean =  $102.30

sample standard deviation = $5.30

So, all the data mean, standard deviation is given

therefore, t-test used and one type of sample used as well

Hence, It is one-sample t-test for sample mean
