Answer : ![P(\text{this group will speak both French and Spanish})=0.141666666](https://tex.z-dn.net/?f=P%28%5Ctext%7Bthis%20group%20will%20speak%20both%20French%20and%20Spanish%7D%29%3D0.141666666)
Explanation:
Since we have given that
n(U) = 120, where U denotes universal set ,
n(F) = 45, where F denotes who speak French,
n(S) = 42 , where S denotes who speak Spanish,
n(F∪S)' = 50
n(F∪S) = n(U)-n(F∪S) = 120-50 = 70
Now, we know the formula, i.e.
n(F∪s) = n(F)+n(S)-n(F∩S)
⇒ 70 = 45+42-n(F∩S)
⇒ 70 = 87- n(F∩S)
⇒ 70-87 = -n(F∩S)
⇒ -17 = -n( F∩S)
⇒ 17 = n(F∩S)
![P(\text{this group will speak both French and Spanish})= \frac{17}{120}\\P(\text{this group will speak both French and Spanish})=0.141666666](https://tex.z-dn.net/?f=P%28%5Ctext%7Bthis%20group%20will%20speak%20both%20French%20and%20Spanish%7D%29%3D%20%5Cfrac%7B17%7D%7B120%7D%5C%5CP%28%5Ctext%7Bthis%20group%20will%20speak%20both%20French%20and%20Spanish%7D%29%3D0.141666666)
The square root of 81 is 9
Your answer is <em>9
</em>Work:
9 x 9 = 81
Answer:
1
Step-by-step explanation:
First, we can find the equation of the parabola. The standard form of a parabola is ax^2 + bx + c,
where c is the y-intercept. The y-intercept on the graph is -5, and every option starts with x^2, so the equation must be x^2 - 5. This rules out options 3 and 4.
Next, we can find the equation of the line. The options are all given in slope-intercept form: y = mx + b, where b is the y-intercept. The y-intercept on the graph is 1, and option 1 has 1 in the place of b. Therefore, option 1 is the answer.
