Find the missing side length. Round to the nearest tenth.


Can someone PLEASE HELP!!

Answers

Answer:

the answer is 17.0 or just 17

Step-by-step explanation:

you have to use the pythagorean theorem, a^2 + b^2 = c^2

a = 11 and b = 13

11^2 + 13^2 = c^2

121 + 169 = c^2

290 = c^2

square root each side, so you have to find the square root of 290 which is 17.0293864

round it to the nearest tenth which is 17.0 but you can just write 17

hope this helps you understand it and answer it :)

Answer:

[tex]\boxed {\boxed {\sf c \approx 17.0}}[/tex]

Step-by-step explanation:

This is a right triangle because of the small square in the corner. Therefore, we can use the Pythagorean Theorem.

[tex]a^2+b^2=c^2[/tex]

Where a and b are the legs and c is the hypotenuse.

In this triangle, 11 and 13 are the legs because they make up the right angle. The missing side is the hypotenuse because it is opposite the right angle.

[tex]a=11\\b= 13[/tex]

[tex](11)^2+(13)^2=c^2[/tex]

Solve the exponents.

11²= 11*11=12113²= 13*13=169

[tex]121+169=c^2[/tex]

Add.

[tex]289=c^2[/tex]

We are trying to solve for c, so we must isolate the variable. It is being squared. The inverse of a square is the square root, so take the square root of both sides.

[tex]\sqrt {289}= \sqrt {c^2}[/tex]

[tex]17.0293864=c[/tex]

Round to the nearest tenth. The 2 in the hundredth place tells us to leave the 0 in the tenth place.

[tex]17.0 \approx c[/tex]

The missing side is approximately 17.0

given that the 11th term of arithmetic progression is 43 that the first term is 3 find the 4th term​

Answers

Answer: 15

Step-by-step explanation:

The 11th term of arithmetic progression is 43. We can use this to get the common difference which will be:

a + (n - 1)d = 43

where,

a = first term = 3

n = nth term = 11

d = common difference = unknown

Therefore, a + (n - 1)d = 43

3 + (11 - 1)d = 43

3 + 10d = 43

10d = 43 - 3

10d = 40

d = 40/10

d = 4

Common difference = 4

Therefore, 4th term will be:

= a + (n - 1)d

= a + (4-1)d

= a + 3d

= 3 + 3(4)

= 3 + 12

= 15

The 4th term is 15

Select the most appropriate response. An event A will occur with probability 0.4. An event B will occur with probability 0.6. The probability that both A and B will occur is 0.20. We may conclude Question options: that events A and B are independent. that events A and B are dependent. that either A or B always occurs. that events A and B are mutually exclusive.

Answers

Answer:

Events A and B are dependent

Step-by-step explanation:

If A and B are two events such as A and B are dependent then

P(A∩B) [tex]\neq[/tex] P(A) P(B)

An event A will occur with probability 0.4 that is [tex]P(A)=0.4[/tex]

An event B will occur with probability 0.6 that is [tex]P(B)=0.6[/tex]

[tex]P(A)P(B)=0.4(0.6)=0.24[/tex]

The probability that both A and B will occur is 0.20 that is P(A∩B) = 0.20

Therefore,

P(A∩B) [tex]\neq[/tex] P(A) P(B)

So,

events A and B are dependent

According to the given probabilities, it is found that events A and B are dependent.

What are independent events?

Two events, A and B are independent, if:

[tex]P(A \cap B) = P(A)P(B)[/tex]

In this problem, the probabilities given are:

[tex]P(A) = 0.4, P(B) = 0.6, P(A \cap B) = 0.2[/tex]

The multiplication is:

[tex]P(A)P(B) = 0.4(0.6) = 0.24[/tex]

Since [tex]P(A)P(B) \neq P(A \cap B)[/tex], the events A and B are dependent.

A random sample of 663 teens who said they did not typically eat fast food reported an average daily calorie intake of 2258, with standard deviation 1519. A random sample of 413 teens who said they did typically eat fast food reported an average daily calorie intake of 2637, with standard deviation 1138. The two populations are moderately positively skewed. Based on the above description, which of the following conditions are met for conducting a hypothesis test for the equality of two means?

a. Both samples are random
b. Samples are independent of one another
c. Both samples are normal enough given the sample size
d. Two population means need to be the same

Answers

Answer:

Option B

Step-by-step explanation:

The sample populations are independent of each other and hence for comparing of mean of two population it is very essential that the two populations independent of each other.

Now here one population set consist of only people who eat fast food and the other set of population consists of people who do not eat fast food.
