Answer:
X-intercepts: (80,0)
y-intercepts: (0,200)
Step-by-step explanation:
(To find the x-intercept, substitut in 0 for y and solve for x. To find the y-intercept, substitute in 0 for x and solve for y. As shown in the pictur)
Answer:
100,800 seconds a week
Step-by-step explanation:
So first you would figure out how many minutes she spends each day watching so, 60 x 4 = 240
then how many seconds a day so 240 x 60 = 14,400 a day
now how many seconds a week 14,400 x 7 = 100,800
Answer:
x=9 or x=-3
Step-by-step explanation:
add one to both sides
take square root of both sides
since (x+3)= + or -6, the add 3 to both sides and subtract 3 to both sides does not matter
I don't think there should be a subtract one from both sides step, but i'm not sure
Answer:
Mean = 1.5
Standard Deviation = 1.206
Step-by-step explanation:
Percentage of Siberian Huskies with two different colored eyes = p = 3% = 0.03
Sample size selected = n = 50
We have to find the mean and standard deviation of the number of puppies with two different colored eyes.
Either the puppies will have two different colored eyes or they won't. Sample size is fixed in this case which is 50. A puppy with two colored eyes is independent of other puppies, this means the trials are independent. The probability of success is fixed in this case which is 3%. This setting satisfies all 4 conditions of a Binomial experiment, so we will use the formula relevant to Binomial experiment to answer this question.
Mean number =
Using the values, we get:
Standard deviation of Binomial experiment is calculated as:
Using the values, we get:
Answer: rectangle.
Step-by-step explanation:
Given points: K(0,0) I(2,2) T(5,-5) E(7,-3)
Distance formula to find distance between and :
i.e. KI = TE and KT= IE, so opposite sides equal.
It can be a parallelogram or rectangle. [if all sides are equal it would be square or rhombus]
IT= KE, i.e. diagonals are equal.
It means KIET is a rectangle.
