98 is the product of Chrissy's height and 7 how do I make this a equation

2 answers:

It's not that hard, It's all substitution! (^O^)/ We would have to assign letters with the key information, soo... H - height C - Chrissy The formula would be: C = 98h In word form; Chrissy equals 98 in height Hope it helps!=^•^=

Understanding the language in math product means to multiply and means plus, therefore h= Chrissy's height 98=h (h+7) 98=h^2+7h o= h^2+7h-98 factor (h-7). (h+14)=0 h= (7 , -14)

5 x {3 x [9 - (4 + 1)]} + 20 ÷ 4 x 2 =

adell [148]

To solve a problem like this, we need to start with the innermost parenthesis. Doing that, we get to 4+1, evaluating it giving us 5. This turns our expression into 5 x {3 x [9 - 5]} + 20 ÷ 4 x 2.

Now, the innermost parenthesis is 9-5. Evaluating that gives us 4. Our expression is now 5 x {3 x 4} + 20 ÷ 4 x 2.

Once again, we go to the innermost parenthesis and evaluate whatever is there. This turns our expression into <span>5 x 12 + 20 ÷ 4 x 2.

Now, we can simply use order of operations to compute that the value of the expression is equal to 70. </span>

A football team has a probability of .75 of winning when playing any of the other four teams in its conference. If the games are

Alexeev081 [22]

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.

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$

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

$C_{n,x} = \frac{n!}{x!(n-x)!}$

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 $p = 0.75$ , and four games means that $n = 4$

If the games are independent, what is the probability the team wins all its conference games?

This is P(X = 4). So

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$

$P(X = 4) = C_{4,4}.(0.75)^{4}.(0.25)^{0} = 0.3164$

0.3164 = 31.64% probability the team wins all its conference games

Please give me the correct answer.Only answer if you're very good at math.

GaryK [48]

Answer:

-9 = 0.45m

Step-by-step explanation:

$0.45m - 9 = 0.9m$

^ Subtract 0.45m from BOTH sides. so $0.9m - 0.45m$ ... etc
Why? So that we can make the equation less complicated. Our goal is to isolate the variable m to be on one side of the "=" sign by itself
That will equal to:

$-9 = 0.45m$ <-- ANSWER
