Answer:

Im pretty sure B is (12, 2)

Step-by-step explanation:

3 ÷ 2 = 1.5

1.5 × 4 = 6

6 + 6 = 12

5 - 3 = 2

A 60-foot tree casts a shadow 85 feet long. The sine of the angle between the ground and the line that connects the tip of the s

s2008m [1.1K]

so leg A would be 60

leg B would be 85

using this we are able to determine the HYP to be 104.04

so sine = opp/HYP

leg A is the opp in this case

sin(theta) = 60/104.04

sin(theta) = 0.57670126874

when we round to the hundredths place we get 0.58

How can relative frequencies be used to help us estimate probabilities occurring in sampling distributions? relative frequencies

morpeh [17]

The <u>correct answer</u> is:

<span>Relative frequencies are the probabilities occurring in sampling distributions.

Explanation:

Relative frequencies are the fraction of times an event occurs within a sample.

This is the same definition as experimental probability; thus relative frequencies are the probabilities occurring in sampling distributions.</span>

What is the domain function y=^4sqrtx-1

Rudik [331]

Answer:

Domain of y= $\sqrt[4]{x-1}$ : is x>=1

Interval notation: [1,∞)

Step-by-step explanation:

We have y= $\sqrt[4]{x-1}$

1) The domain of a function is the set of x values for which the function is real and defined.

2) So, x-1 should be positive means x-1>=0, because fourth root of any negative value would be a complex number and not a real number.

3) Now we solve the inequality x-1>=0

4) Adding 1 to both sides of the inequality we get,

x-1+1 > = 0+1

5) Cancel out -1 and +1 from the left side

6) We get x>=1

It concludes that for the domain of the given function, the x value must be greater than or equal to 1

M and n are both integers. Select all the statements that are true if m and n are also equal to each other.

telo118 [61]

The question is incomplete. The complete question is :

M and n are both integers. Select all the statements that are true if m and n are also equal to each other.

A. m - n = n - m

B. 0 = m - n

C. m + (-n) = m - n

D. m + n = 0

Answer :

A. m - n = n - m

B. 0 = m - n

C. m + (-n) = m - n

Explanation :

It is given that m and n are integers and they both are equal to each other.

i.e. m = n

Therefore for option (A),

m - n = n - m

m - m = m - m (since m and n are equal)

0 = 0

Therefore, the statement (A) is true.

For option (B),

0 = m - n

0 = m - m (since m and n are equal)

0 = 0

Therefore, the statement (B) is true.

For option (C),

m + (-n) = m - n

m + (-m) = m - m (since m and n are equal)

m - m = m - m

0 = 0

Therefore, the statement (C) is true.

Now for option (D),

m + n = 0

m + m ≠ 0 (since m and n are equal)

2m ≠ 0

Therefore, the statement (D) is false.

Hence, the options (A), (B) and (C) are true.
