Formula for this is as follows:
probability of her passing both 0.6/0.8 - first test and this is a fraction. 0.6/0.8
0.6/0.8= divide 0.6 by 0.8=0.75
that means probability of her passing the second test is 75%

Identify the factors of 6ab − 8a + 21b − 28. (5 points)
cupoosta [38]
Rearrange to

6ab+21b-8a-28 now factor 1st and 2nd pair of terms...

3b(2a+7)-4(2a+7)

(3b-4)(2a+7)

So it is the third one down...

Write the sentences as proportion. Twelve hundredths is to three as twenty-four hundredths is to eight
ValentinkaMS [17]

Answer:

see the explanation

Step-by-step explanation:

Remember that

A proportion is the ratio (quotient) between two numbers

so

Twelve hundredths to three is ----> \frac{0.12}{3}

Twenty-four hundredths to eight ----> \frac{0.24}{8}

therefore

Twelve hundredths is to three as twenty-four hundredths is to eight

\frac{0.12}{3}=\frac{0.24}{8}

Note The proportion is not true

1. Simplify 2/radical 5
cupoosta [38]
1.  (2√5)/5
2.  -44√7
3.  8√17
4.  -6√3+12

For 1:  Multiply the numerator and denominator by √5:
\frac{2}{\sqrt{5}}\times \frac{\sqrt{5}}{\sqrt{5}}=\frac{2\sqrt{5}}{5}

For 2:  Simplify √112:
√112 = √(2*56) = √(2*2*28) = √(4*4*7) = 2*2√7 = 4√7
Now multiply by the -11 coefficient:
-11(4√7) = -44√7

For 3:  Add the radicals as you would variables that are like terms.

For 4:  Multiply by the conjugate.  The conjugate of the denominator has the same values with the sign of the radical changed:
\frac{6}{\sqrt{3}+2}\times \frac{\sqrt{3}-2}{\sqrt{3}-2}=\frac{6(\sqrt{3}-2)}{(\sqrt{3}+2)(\sqrt{3}-2)}
\\
\\=\frac{6\sqrt{3}-6*2}{\sqrt{3}*\sqrt{3}-2\sqrt{3}+2\sqrt{3}-2*2}
\\
\\=\frac{6\sqrt{3}-12}{3-4}=\frac{6\sqrt{3}-12}{-1}=-6\sqrt{3}+12
