Find the exponential regression equation that best fits the data: (10,4), (12,20), (13,35), and (16, 300).
a. y = 0.003(2.04)ˣ
b.y = 2.04(0.003)ˣ
c.y = 11.27(1.00)ˣ
d.y = 1.00(11.27)ˣ

Answers

Answer:

a

Step-by-step explanation:

most likely the answer is a because we have (10,4), 10 being the domain(X-Intercept) and 4 being range(Y-Intercept)

if we substitute the value of X in option a with 10, we get a value of 3.7 as shown in the picture which can be can be converted to 4

Answer:

- 3, - 2, - 1 and 6

Step-by-step explanation:

To find the first 3 terms, substitute n = 1, 2, 3 into the nth term rule

a₁ = 1 - 4 = - 3

a₂ = 2 - 4 = - 2

a₃ = 3 - 4 = - 1

The first 3 terms are - 3, - 2, - 1

similarly substitute n = 10 into the rule for 10th term

a₁₀ = 10 - 4 = 6

in group of 60 students, 15 liked math only , 20 liked science only and 5 did not like any two subject how many student like math

Answers

Answer:

i) no. of students like none of subject = 5

total no. of students= 69

=> no. of students like at least one subject= 60-5

= 55

ii) no. of students like math only = 15

no. of students like science only = 20

total no. of students like only one subject= 35

no. of students like none subject = 5

=> no of students like both the subjects = 60-(35+5) =20

(iii) no. of students like math= 15+ 20

= 35 ( because 15 like math only and 20 like both)

(iv) no. of students like science= 20+20

= 40 ( because 20 like science only and 20 like both )

Step-by-step explanation:

daniiel is currently 26 years older than his son. in 6 years he will be three times older than his son. how old are both of them now?

Answers

Answer:

Daniiel is 33 years old.

The son is 7 years old.

Step-by-step explanation:

x+26=3x

The x represents the son.

To solve for x:

-26=x-3x

-26=-2x

x=13

Since the father will be 3 times his son's age in six years we subtract 6.

x=7

This means the son is 7 years old as of right now. To find the father's age you do 7+26=33
