Answer:
114
Step-by-step explanation:
Because u do 9+10 which equals 19 and then u do 19*6 and u get 114 so the expression now would be 6=114/(9+10)
**Find the component form of the resultant vector.**
Answer:
[tex]\overrightarrow{AB}+\overrightarrow{CD}=(-3,-7)[/tex]
Step-by-step explanation:
Vector Addition
We are given the points A=(1,3), B=(-4,5), C=(-2,10), D=(0,1). Find:
[tex]\overrightarrow{AB}+\overrightarrow{CD}[/tex]
First, find both vectors from the initial and final points:
[tex]\overrightarrow{AB}=(-4-1,5-3)=(-5,2)[/tex]
[tex]\overrightarrow{CD}=(0-(-2),1-10)=(2,-9)[/tex]
Now find the sum of both vector by adding the components separately:
[tex]\overrightarrow{AB}+\overrightarrow{CD}=(-5,2)+(2,-9)=(-3,-7)[/tex]
[tex]\boxed{\overrightarrow{AB}+\overrightarrow{CD}=(-3,-7)}[/tex]

The sum of the square of a positive number and the square of 3 or more than the numbers is 17. What is the number
Answer:
1
Step-by-step explanation:
Let x represent the number. The given relation is ...
x² +(x+3)² = 17
2x² +6x +9 = 17 . . . . simplify
x² +3x -4 = 0 . . . . . . subtract 17 and divide by 2
(x +4)(x -1) = 0 . . . . . factor
The solutions make these factors zero: -4 and +1. The positive solution is 1.
The number is 1.

determine if the function f(x)=3^(2x-3) is exponential
An exponential function gives a variable raised to the power of x, where the variable is a positive real number
Yes, [tex]\underline{f(x) = 3 ^{(2 \cdot x - 3)}}[/tex] is an exponential function
Reason:
An exponential function is a function that can be written in the form;
f(x) = eˣ
Where;
e = Euler's number, which is the number approximately 2.71828
In the general form, an exponential number is a number given in the form;
f(x) = a·bˣ
Where;
b = A positive real number
The given function; [tex]f(x) = 3 ^{(2 \cdot x - 3)} = \dfrac{3^{2\cdot x}}{3^3} = \dfrac{1}{27} \times 9^x[/tex] is an exponential function
Where;
a = [tex]\dfrac{1}{27}[/tex]b = 9Therefore, the correct response is; Yes, [tex]f(x) = 3 ^{(2 \cdot x - 3)}[/tex] is an exponential function

Which of the following equations is equivalent to x + y = 10?
Answer:
x + y - 10 = 0
Step-by-step explanation:
x + y - 10 = 10 -10
Move the constant to the left by adding its opposite to both sides
x + y - 10 = 0
The sum of two opposites equals 0
x + y - 10 = 0

Lances goal is to run 16 laps around the track. Each lap is 350 yards. Currently lances ran 2450 yards around the track. How much is his percent did he run so far??
Answer:
Hi There!
Your answer is :
He ran 43.75% so far.
Step-by-step explanation:
16 laps = GOAL
350* 16 to determine goal yards
16laps = 5,600yrds
1 lap= 350 yrds
xlaps = 2450 yrds
2450/350 to determine x laps.
7 laps = 2450 yards
He is 2450 yards into his 5,600 yard goal.
IF 5,600 = 100%
/5600
1 yard = 1/56th %
* 2450
2450yards = 43.75%

A health psychologist knew that corporate executives in general have an average score of 2.55 with a standard deviation of 0.5 on a stress inventory and that the scores are normally distributed. In order to learn whether corporate executives who exercise regularly have different stress scores, the psychologist measured the stress of 30 exercising executives and found them to have a mean score of 2.76. a. Using the five steps of hypothesis testing, was the group of 30 exercising executives different from executives in general? (Use the .05 significance level.) Be sure to sketch the distributions involved. Be sure to fully state the five steps and show ALL calculations/work. b. Additionally, explain the logic of what you did to a person who understands hypothesis testing for studies in which the sample consists of a single individual but is unfamiliar with hypothesis testing involving a sample of more than one individual. (Be sure your explanation includes a discussion of the distribution of means--what it is, what it is made of, the concept of how it is created, how itʹs characteristics are created, its role in the overall hypothesis testing process.)
Answer:
Kindly check explanation
Step-by-step explanation:
Given the following :
Population mean (μ) = 2.55
Population standard deviation (σ) = 0.5
Sample size (n) = 30
Sample mean (x) = 2.76
α = 0.05
STEP 1:
Stress score in general executive (s1)
Stress score in exercising executive (s2)
Null : s1 = s2
Alternative : s1 < s2
STEP 2:
Shape of distribution = normal
Population mean (μ) = 2.55
Population standard deviation (σ) = 0.5
Sample size (n) = 30
Sample mean (x) = 2.76
α = 0.05
Decision rule :
α = 0.05 which corresponds to a t score (t0) ;
df = n - 1 = 30 - 1= 30 at 0.05 = 1.699
If :
(Test statistic (t) > t0) ; reject the Null
(right tailed test)
Test statistic (t) :
(x - μ) / (σ/√n)
(2.76 - 2.55) / (0.5/√30)
0.21 / 0.0913
= 2.30
t > t0
2.30 > 1.699
t is more extreme than t0
Hence, reject the null at α = 0.05

Answer: it’s 66 I got it right
Step-by-step explanation:
Answer:
The answer will be 66 !!
Step-by-step explanation:
The answer will be 66 because if you look at the chart you can see how much money is cost to rent a bike for each hour. So for Ari, as he rented a bike it costs 9 dollars per hour. So Ari rented the bike for 4 hours, so multiply 4x9=36. Now for Meg, she rented a scooter for 3 hours, each hour means 10$. Now 3x10=30, Then just add 36+30 you get 66!
