Step-by-step explanation:

Answer:

Solutions given;

Using cosine rule

b²=a²+c²-2*a*c*cos B°

b²=15²+8²-2*15*8*cos39

b²=102.48

b=[tex] \sqrt{102.48} [/tex]

b=10.12

b=10.1

Using sine rule

[tex] \frac{sin A}{BC} = \frac{sin B}{AC} =\frac{sin C}{AB} [/tex]

[tex] \frac{sin 29°}{15} =\frac{sin C}{8} [/tex]

Doing criss cross multiplication

Sin C=[tex] \frac{sin 29°}{15} ×8[/tex]

m<C=Sin -¹(0.29)

m<C=14.98

m<C=15°is a required answer.

Answer:

1.80 hours or 1 hour  and 48 minutes

Step-by-step explanation:

Jerry = 3 miles every hour

Jerry took 3 hours to climb the hill.

It is safe to say that he traveled 3 miles every hour for 3 hours so he traveled 3 x 3 = 9 miles in all.

Jim walks at a speed of 5 miles an hour.

Question : How many hours would it take to travel 9 miles

9/5 = 1 4/5 of an hour

1 4/5 of an hour 1 hour 48 minutes

Step-by-step explanation: The only one that’s not included in the pattern

Step-by-step explanation:

You can see that the shaded parts are moving counterclockwise (I think) so if you continue the pattern then you will get A.

Answer:

(-18, 9)

Step-by-step explanation:

If a coordinate A(x,y) is dilated by a factor of k, the new coordinates will be expressed as;

A' = (kx, ky)

A' = A (kx, ky)

Given the following

k = 1/3

A' = (-6, 3)

Substitute

(-6, 3) = 1/3(x, y)

Cross multiply

3(-6, 3) = (x, y)

(x, y) = (3(-6), 3(3))

(x, y) = (-18, 9)

Hence the coordinate prior to dilation is (-18, 9)

Step-by-step explanation:

The first part of the preamble states, "We the People of the United States, in Order to form a more perfect Union..." The United States government was built by the people, for the people. It was important to the founding fathers that there could be a democracy where the people could hold the power of the government. So, they wrote this into the constitution and preamble.

Answer: 3x+18=5x-2

Step-by-step explanation:

Answer:

the answer is B because theres no negative

Answer:

2x+ (x-1) = 8

Simplified

3x-1 =8

Step-by-step explanation:

y=x−1

2x+y=8

Take the first equation and everywhere you see y in the second equation substitute x-1

2x+ (x-1) = 8

You can simplify

2x+x-1 =8

3x-1 =8

If you want to solve

3x-1+1 =8+1

3x= 9

Divide by 3

3x/3 =9/3

x=1

Then solve for y

y = x-1

y = 3-1

y=2

Answer:

Step-by-step explanation:

290g+450g+670g = 1,410g

1g = 0.001kg

1410g = 1.41kg

Answer:

A.1.41

Step-by-step explanation: 290+450+670=1410 grams. One kilogram is 1000 grams so 1410 grams is 1.41 kilograms.

Answer:

2 2/7 + 4 1/2

Step-by-step explanation:

Exact form 95/14 for me

Mixed number will be 6 11/14

2 2/7 + 4 1/2 simplified fraction is 95/14.

To simplify the expression 2 2/7 + 4 1/2, we can convert the mixed numbers to improper fractions and then add them together.

Converting the mixed numbers to improper fractions:

2 2/7 can be written as (2 x 7 + 2)/7 = 16/7

4 1/2 can be written as (4 x 2 + 1)/2 = 9/2

Now we can add the fractions together:

16/7 + 9/2

To add fractions, we need to have a common denominator. In this case, the least common denominator (LCD) of 7 and 2 is 14.

Converting both fractions to have a denominator of 14:

16/7 x 2/2 = 32/14

9/2 x 7/7 = 63/14

Now we can add the fractions:

32/14 + 63/14 = (32 + 63)/14 = 95/14

Therefore, 2 2/7 + 4 1/2 simplified is 95/14.

Answer:

0.2776 = 27.76% probability that fewer than 40% of the customers in the sample purchased the service contract.

Step-by-step explanation:

To solve this question, we need to understand the normal probability distribution and the central limit theorem.

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.

Central Limit Theorem

The Central Limit Theorem establishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].

For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.

For a proportion p in a sample of size n, the sampling distribution of the sample proportion will be approximately normal with mean [tex]\mu = p[/tex] and standard deviation [tex]s = \sqrt{\frac{p(1-p)}{n}}[/tex]

45% of these customers also purchased the extended service contract.

This means that [tex]p = 0.45[/tex]

Sample of 35

This means that [tex]n = 35[/tex]

Mean and standard deviation:

[tex]\mu = 0.45[/tex]

[tex]s = \sqrt{\frac{0.45*0.55}{35}} = 0.0841[/tex]

What is the probability that fewer than 40% of the customers in the sample purchased the service contract?

This is the p-value of Z when X = 0.4. So

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

By the Central Limit Theorem

[tex]Z = \frac{X - \mu}{s}[/tex]

[tex]Z = \frac{0.4 - 0.45}{0.0841}[/tex]

[tex]Z = -0.59[/tex]

[tex]Z = -0.59[/tex] has a p-value of 0.2776

0.2776 = 27.76% probability that fewer than 40% of the customers in the sample purchased the service contract.
