To get the percent change, take the final value (100) - initial value (2) and divide the difference by the initial value (2) and multiply the quotient by 100 to get the percent increase.

100 - 2 = 98

98 / 2 = 49.

49 * 100 = 4900%

There was a 4,900% increase

Answer:

4900%

Step-by-step explanation:

the increase is 100-2=98 pounds

98=p/100 * 2

2p=98*100

p=9800/2

p=4900

Th term of a seq uence is n(n-4) /n+3 Work out the sum of the 1st and 6th terms.

AlekseyPX

Answer:

7/12

Step-by-step explanation:

The nth term Tₙ = n(n-4) /n+3.

The 1st term T₁ = 1(1 - 4)/(1 + 3) = -3/4

The 6th term T₆ = 6(6 - 4)/(6 + 3) = 6(2)/9 = 2(2)/3 = 4/3

So, the sum of the 1st and 6th terms is T₁ + T₆ = -3/4 + 4/3

= (-9 + 16)/12

= 7/12

The accompanying table describes results from groups of 8 births from 8 different sets of parents. The random variable x represe

insens350 [35]

Using the discrete probability outputs given in the attached table ; the probability values of having exactly 6 ; and having 6 or more girls are :

P(X = 6) = 0.111

P(X ≥ 6) = 0.1

The probability of having exactly 6 girls can be defined as :

P(X = 6) = 0.111 (from the discrete probability table)

2.)

The probability of having 6 or more girls can be defined as :

P(X ≥ 6) = P(X = 6) + P(X = 7) + P(X = 8)

From the table attached :

P(X ≥ 6) = 0.111 + 0.014 + 0.003 = 0.1

Therefore, the probability of having exactly 6 girls is 0.111 while the probability of having 6 or more girls is 0.1

Due tomorrow plz help. D-F3

Nostrana [21]

D.
slope = -3
passing thru(4,3)
y = mx + b
3 = -3(4) + b
b = 15

equation
y = -3x + 15

E.
(4,5)(6,9)
slope = (9-5)/(6-4) = 4/2 = 2
passing thru (4,5)(6,9)
y = mx + b
5 = 2(4) + b
b = -3

equation
y = 2x - 3
