1. Elena did 16 push-ups.
2. Jada did 42 push-ups.
3. Lin did 13 push-ups.
4. Andre did 21 push-ups.
Answers
Answer:
1- 80%
2- 210%
3- 65%
4- 105%
Step-by-step explanation:
The percentage of the goal achieved by them:
1). 80%
2). 210%
3). 65%
4). 105%
Find the percentage
1). Goal of push-ups = 20
No. of push-ups done by Elena = 16
Percentage = 16/20 × 100
= 80%
2). Goal of push-ups = 20
No. of push-ups done by Jada = 42
Percentage = 42/20 × 100
= 210%
3). Goal of push-ups = 20
No. of push-ups done by Lin = 13
Percentage = 13/20 × 100
= 65%
4). Goal of push-ups = 20
No. of push-ups done by Andre = 21
Percentage = 21/20 × 100
= 105%
Thus, the above answers are correct.

La media de una población es 683.5g y su desviación estándar 52.1g. Determina la puntuación estándar para el valor 652.1
Answers
Respuesta:
- 0,60
Explicación paso a paso:
Dado que:
Media poblacional, μ = 683,5
Desviación estándar, σ = 52,1
Puntuación, x = 652,1
La puntuación estandarizada, Z = (x - μ) / σ
Puntuación Z = (652,1 - 683,5) / 52,1
Puntuación Z = - 31,4 / 52,1
Zscore = −0.602687
Puntaje estandarizado = - 0.60

Answers
Answer:
Remember the formula for the slope which is change in y over change in x
therefore: (7+2)/(6+3)= 1 slope=1
formula for a line is y=mx+b
plug in your slope and one of the given coordinates to find the y-intercept:
y=1x+b
7=1(6)+b
7=6+b
1=b
so the equation for the line would be y=x+1

If 10x=5, then x would be equal to 1/2.
You'd simply divide 10 by 5 to solve for x.
The value of x is 1/2.
What is algebra?Algebra is a branch of mathematics dealing with symbols and the rules for manipulating those symbols.
In elementary algebra, those symbols (today written as Latin and Greek letters) represent quantities without fixed values, known as variables.
Given:
10x=5
Divide both side by 10
10x/10=5/10
x=5/10
x=1/2
