5. Given that the probability of getting the intended number when a telephone call is made in a city is 0.99 . a) Ten independent calls are made. Find the probability of getting nine or more of the intended numbers. 0.998st b) Six hundred independent calls are made. Find the probability of failing to get the intended number on at least ten but not more than twelve of the calls. \( 0.0 \times 17 \)

Ava adds to the next ten to find \( 65+25 \). Tell how she might find the sum.

2) \( \frac{13}{m}=\frac{19}{m+24} \)

Fila \( B \quad \) Desaso \( h a x \) \( a=3 \) \( b=-5 \) \( c=-1 \) \( f(x)=-2 x^{2}+3 x-4 \)

Which of the following is the correct interpretation of a value \( x \) that has a \( z \)-score of 0.75 ? There is \( 75 \% \) chance of getting a value smaller than \( x \) \( x \) is 0.75 standard deviations below the mean There is \( 75 \% \) chance of getting a value larger than \( x \) There is \( 75 \% \) chance of getting a value equal to \( x \) \( x \) is 0.75 standard deviations above the mean 2 nts
