Answer:
The x-intercept=7
Step-by-step explanation:
Step 1
Given the equation;
y=-x+7, is a linear equation
Step 2
The x-intercept is the value of x when the graph crosses the x-axis. At this point, the value of y=0
Step 3
Substitute the value of y in the linear equation above to solve for the x-intercept.
Given;
y=0
And the linear equation is;
y=-x+7
replace;
0=-x+7
x=7
The x-intercept=7
Answer:
0.3164 = 31.64% probability the team wins all its conference games
Step-by-step explanation:
For each conference game, there are only two possible outcomes. Either the team wins it, or they lose. The probability of winning a game is independent of any other game. This means that the binomial probability distribution is used to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

In which
is the number of different combinations of x objects from a set of n elements, given by the following formula.

And p is the probability of X happening.
A football team has a probability of .75 of winning when playing any of the other four teams in its conference.
The probability means that
, and four games means that 
If the games are independent, what is the probability the team wins all its conference games?
This is P(X = 4). So


0.3164 = 31.64% probability the team wins all its conference games
Answer:
3x³ + 12x
Step-by-step explanation:
3x is 3 times x. If we multiply x times x², we get x³. This is because x² can be written as x·x, so if we multiply x by that, we get x·x·x. Since we are multiplying x² by 3x, we get 3x³. Now, we multiply 3x by 4, this gets us 12x. Now, we write it out as 3x³ + 12x.
Answer:
Renu is 30.
Step-by-step explanation:
Suman is 15, Renu is 30, and Anita is 24.
15 + 30 + 24 is 69.
Answer:
A then B
Step-by-step explanation:
1440≈1,000, and 1,000=10^3
1000000/1440≈700, and 700≈1,000. 1,000=10^3
