Increased by 15
past score was x
increased by 15 means he raised to 15+x
it was raised to 83%

therefor
x+15=83

first option is right (and first test was 68%)

Answer:

The correct equation is  x+15=83

Option 1 is correct.

Step-by-step explanation:

When Jose took the test over, he increased his score by 15% points

Let he scored in first test x%

In second test scored 83% which was 15% more than first test.

He increased his score by 15% points from first test.

Thus, Scored in second test = x + 15

We are given second test scored 83%

Therefore, x+15 must be equal to 83

Hence, The correct equation is  x+15=83

Fittoniya [83]

Answer:

n= 2/3 - 5/6k , ker

Step-by-step explanation:

-2n-5k+8-4n-11=-7

-6n-5k+8-11=-7

-6n=-7+3+5k

-6n=-4+5k

then divide both sides by -6 to get your answer

n= 2/3 - 5/6k , ker

A leading magazine (like Barron's) reported at one time that the average number of weeks an individual is unemployed is 27 weeks
miss Akunina [59]

Answer:

X ~ N(27, 4) ;

xbar ~ N(27, 0.1026) ;

0.5 ;

0.5

Step-by-step explanation:

Probability distribution of X : N(μ, σ²)

μ = 27 ; σ = 2

X ~ N(μ, σ²) = X ~ N(27, 2²) ;X ~ N(27, 4)

Distribution is approximately normal ; μ = xbar ; xbar = 27

(Standard Error)² = (σ/√n)²= (2/√39)² = 0.1026

xbar ~ N(μ, σ²) = xbar ~ N(27, 2²) ; xbar ~ N(27, 0.1026)

Probability that a randomly selected individual found a job in less than 27 weeks :

P(X < 27) :

Obtain the Zscore :

Z = (x - μ) / σ

Z = (27 - 27) / 2 = 0/2

Z = 0

P(Z < 0) = 0.5

D.) n = 36

P(X < 27) :

Obtain the Zscore :

Z = (x - μ) / σ/√n

Z = (27 - 27) / (2/√36) = 0/0.33333

Z = 0

P(Z < 0) = 0.5
