Step-by-step explanation:
Given:
Two points
(a, b) (c, d)
Find:
Distance
Computation:
Distance = √(x1 - x2)² + (y1 - y2)²
So,
Distance = √(a - c)² + (b - d)²

Answers
Answer:
8
Step-by-step explanation:
The probability that Jaclyn wins exactly 2 times is 0.073
What is binomial probability?Binomial probability is the probability of exactly x successes on n repeated trials in an experiment with two possible outcomes. If the probability of success on an individual trial is p, then the binomial probability is ⁿCₓ⋅pˣ⋅(1−p)ⁿ⁻ˣ. Here ⁿCₓ indicates the number of different combinations of x objects selected from a set of n objects.
Given here:
She plays 16 times and the probability of her winning is 0.3
Thus applying the formula we get
= ¹⁶C₂× 0.3²× 0.7¹⁴
= 120×0.09×0.7¹⁴
=0.073
Hence, The probability that Jaclyn wins exactly 2 times is 0.073

Step-by-step explanation:
1=5 80/5=16
1=9 2x9=18
Answer:
16 centimeters and 18 feet
Step-by-step explanation:
The scale for the fist one is 1 centimeter and that gives you 5 meters. So set up a proportion to see what 80 meters would get you. 1cm/5m=Xcm/80m. You would divide 80 by 5 to find the amount of centimeters which would be 16.
For the next one it is similar. Set up the proportion 1in/9ft=2in/Xft. You would end up with x=9times2 which would give you 18 ft.

Answers
Sorry to disappoint, but none of these answers are correct. All three limits are equal to 7.
Compute the one-sided limits:
[tex]\displaystyle\lim_{x\to2^-}h(x)=\lim_{x\to2}(x^2-x+5)=2^2-2+5=7[/tex]
[tex]\displaystyle\lim_{x\to2^+}h(x)=\lim_{x\to2}(x^3-1)=2^3-1=7[/tex]
Both the one-sided limits agree, so the two-sided limit has the same value,
[tex]\displaystyle\lim_{x\to2}h(x)=7[/tex]

Seven students volunteered for a comparison of study guides for an advanced course in mathematics. They were randomly assigned, four to study guide A and three to study guide B. All were instructed to study independently. Following a two-day study period, all students were given an examination about the material covered by the guides, with the following results:Study Guide A scores: 68; 77; 82; 85Study Guide B scores: 53; 64; 71Perform a randomization test by listing all possible ways that these students could have been randomized to two groups. There are 35 ways. For each outcome, calculate the difference between sample averages. Finally, calculate the two-sided p-value for the observed outcome

options(digits =2(
scores<- c(68,77,82,85,53,64,71)

Step-by-step explanation:
Expression (x + 1 - i)(x + 1 + i) is equivalent to x² + 2x +2.
Option (B) is correct option.
What is an algebraic expression?Variables, integers, and a variety of mathematical procedures make up an algebraic expression.
To find the expression equivalent to x² + 2x +2,
Solve with the help of options.
(A)
(x - 1 + i)(x - 1 - i)
Solve by using formula (a + b)(a - b) = a² - b²
(x - 1 + i)(x - 1 - i) = (x -1)² - i² = x² + 1 - 2x +1 = x² - 2x + 2
(B)
(x + 1 - i)(x + 1 - i)
Solve by using formula (a + b)(a - b) = a² - b²
(x + 1 - i)(x + 1 + i) = (x + 1)² - i² = x² + 1 + 2x +1 = x² + 2x + 2
Expression in option (B) is equivalent to x² + 2x + 2.
