A traveling soccer team allows only the top 3% of athletes who try out to be part of the team. If the team tryout scorecard has

skad [1K]

Answer:

169

Step-by-step explanation:

You need to use a Z-table for this.

There are different tables, in this table i searched for the probability of 97% because that equivalent to the top 3%.

for 0.97, Z = 1.88

The formula of Z is:

$Z = (x-mean)/(st. dev.)$

Solving x:

$1.88 = (x-150)/10 \\x = 168.8 = 169$

Patty prepared a simple salt solution using 3 parts salt and 4 parts water. Timmy made a salt solution using 6 parts salt and 7

777dan777 [17]

Answer:

The solution of Timmy is saltier.

Step-by-step explanation:

We have to keep in mind that a solution is saltier if and only if salt has a greater proportion within solution. The following criterion is used to determine which solution is saltier:

$r = \frac{n_{salt}}{n_{salt}+n_{water}}$

Where:

$r$ - Salt ratio, dimensionless.

$n_{salt}$ - Parts of salt, dimensionless.

$n_{water}$ - Parts of water, dimensionless.

Now, we find the salt ratios of Patty and Timmy:

Patty ( $n_{salt} = 3$ and $n_{water} = 4$ )

$r_{P} = \frac{3}{3+4}$

$r_{P} = \frac{3}{7}$

$r_{P} = 0.429$

Timmy ( $n_{salt} = 6$ and $n_{water} = 7$ )

$r_{T} = \frac{6}{6+7}$

$r_{T}= \frac{6}{13}$

$r_{T} = 0.462$

The solution of Timmy is saltier.
