A football quarterback enjoys practicing his long passes over 40 yards. He misses the first pass 40% of the time. When he misses on the first pass, he misses the second pass 20% of the time. What is the probability of missing two passes in a row?

Answer:

30%

Step-by-step explanation:

If a football quarterback enjoys practicing his long passes over 40 yards and misses the first pass 40% of the time, but when he misses on the first pass, he misses the second pass 20% of the time. The probability of missing two passes in a row is 30%.

First pass: 40%

Second pass: 20%

40% and 20% combined/average is 30%.

Therefore, the probability of missing two passes in a row is 30%.

A number, plus one-third of itself, plus one-eighth of itself, equals 70. What is the number?
Alex73 [517]
X - the number

x+\frac{1}{3}x+\frac{1}{8}x=70 \\
\frac{24}{24}x+\frac{8}{24}x+\frac{3}{24}x=70 \\
\frac{35}{24}x=70 \\
x=70 \times \frac{24}{35} \\
x=2 \times 24 \\
x=48

The number is 48.

I RLLY NEED HELP PLS!!

Answer:  (x+2)^2+3\\\\

a = 2 and b = 3

==================================================

Explanation:

Let's expand out (x+a)^2+b to get the following:

(x+a)^2+b\\\\(x+a)(x+a)+b\\\\x(x+a)+a(x+a)+b\\\\x^2+ax+ax+a^2+b\\\\x^2+2ax+a^2+b\\\\

The x term here is 2ax

Compare this to the x term of x^2+4x+7 and we see that

2ax = 4x\\\\2a = 4\\\\a = 4/2\\\\a = 2\\\\

--------------

The constant term of x^2+2ax+a^2+b\\\\ is the a^2+b portion since it doesn't have the variable x attached to it.

Compare this with the 7 of x^2+4x+7 which is also the constant.

Equate the two items, plug in a = 2 and solve for b.

a^2+b = 7\\\\2^2+b = 7\\\\4+b = 7\\\\b = 7-4\\\\b = 3\\\\

Therefore,

x^2+4x+7 = (x+a)^2+b\\\\x^2+4x+7 = (x+2)^2+3\\\\

Which equation could be used to find the length of the hypotenuse?
never [62]

Hey!

The formula for finding the length of the hypotenuse is:

a^{2} + b^{2} = c^{2}

That means you have to square both numbers.

6\ squared = 6^{2} \\ 11\ squared = 11^{2}

That gives you:

6^{2} + 11^{2} = c^{2}

<em>That means your answer is the first choice</em>

\framebox{Answer = 1st choice}
