We want double sixes. This means that we want both the first roll and the second roll to be 6.

The given point is given as (r1 , r2) where:
r1 is output from first roll
r2 is output from second roll

Since we want both outputs to be 6, therefore, the answer would be: (6,6)

The probability, P, that a person responds to an advertisement can be modeled by the exponential function P = 1 – e^-0.047t. In

Ray Of Light [21]

Answer:

c. 60.9%

Step-by-step explanation:

Given:

The probability P that a person responds to an advertisement can be modeled by the function:

$P=1-e^{-0.047t}$

where $t$ represents number of days since the advertisement first appeared.

To find the probability that a person has responded after 20 days.

Solution:

In order to find the probability that a person has responded after 20 days, we will plugin $t=20$ in the formula given.

We have:

$P(t)=1-e^{-0.047t}$

Plugging in $t=20$

$P(20)=1-e^{-0.047(20)}$

$P=1-e^{-0.94}$

$P=1-e^{-0.047t}$

$P=1-0.3906$

$P=0.6094$

Thus, probability $P$ after 20 days = 0.6094

The probability in percentage can be given = $0.6094\times 100$ = 60.9%

The sum of the three interior angles of any triangle equal 180 degrees. One right triangle has one acute angle of 30 degrees.

ELEN [110]

Answer: right triangle is a triangle with one angle equal 90. That being said, the total of all angles = 180. 1 of them is 90 which makes the sum of the 2 acute angles = 90. One acute angle = 30 => the second one = 90 - 30 = 60 degree

Factor gcf 5ab^2 + 10ab

Mrrafil [7]

<span>5ab^2 + 10ab

5ab^2 = 5ab *(b)
10ab = 5ab *(2)

so GCF of </span>5ab^2 + 10ab = 5ab

Please could I have some help :)

Answer:

a) x = 128 degrees

b) Angle APD is the arc angle, which is equal to the central angle x subtended by the arc. Therefore angle APD = 128 degrees (and not 116 degrees)

Step-by-step explanation:

Given:

attached diagram

ABC is a straight line

Solution:

a) Find x

ABC is a straight line

angle ABD = supplement of CBD = 180-CBD = 180-116 = 64 degrees.

x is the central angle of the arc APD

so angle ABD is the inscribed angle which equals half of the arc angle =>

angle ABD = x/2 = 64 degrees

Solve for x

x/2 = 64

x = 2*64

x = 128 degrees

Angle APD is the arc angle, which is equal to the central angle x subtended by the arc. Therefore angle APD = 128 degrees (and not 116 degrees)
