NEED ANSWER QUICKLY PLEASE
Sliva [168]
(3x -11) + 44 + (4x-7) = 180

3x - 11 + 44 + 4x - 7 = 180 like terms

7x +26 = 180

7x = 154

X = 22

Angle 1
3(22) -11
55
Angle 2
4(22) -7
81
So the largest angle is 81 degrees!

Hope this helps!

A statistics professor plans classes so carefully that the lengths of her classes are uniformly distributed between 48.0 and 58.
Yanka [14]

Answer: 0.025

Step-by-step explanation:

Given : A statistics professor plans classes so carefully that the lengths of her classes are uniformly distributed between the interval [48.0 minutes, 58.0 minutes].

The probability density function :-

f(x)=\dfrac{1}{58-48}=\dfrac{1}{10}

Now, the probability that a given class period runs between 50.25 and 50.5 minutes is given by :-

\int^{50.5}_{50.25}\ f(x)\ dx\\\\=\int^{50.5}_{50.25}\ \dfrac{1}{10}\ dx\\\\=\dfrac{1}{10}|x|^{50.5}_{50.25}\\\\=\dfrac{1}{10}\ [50.5-50.25]=\dfrac{1}{10}\times(0.25)=0.025

Hence, the probability that a given class period runs between 50.25 and 50.5 minutes =0.025

Similarly , the probability of selecting a class that runs between 50.25 and 50.5 minutes = 0.025

What is the greatest common factor of 8b^2 and 10b
Mariulka [41]

Answer:

2b

Step-by-step explanation:

The greatest common factor is the largest factor shared by the set of terms.

In this case, you will divide 2b from both terms:

\frac{8b^2}{2b} = 4b\\ \frac{10b}{2b} = 5 \\\\GCF: 2b
