The gym has 4 times as many baseballs than basketballs the gym has 25 total balls how many more baseballs than basket balls does

ELEN [110]

Let $b$ be the number of baseball and $k$ be the number of basket ball.

We have the following system:

$\begin{cases}b=4k\\b+k=25\end{cases}$

Substitute the first equation into the second:

$4k+k=25 \iff 5k=25 \iff k=5$

which yields

$b=4k=4\cdot 5 = 20$

So, there are 20 baseballs and 5 basketballs, meaning that there are 15 more baseballs than basketballs.

Elroy enjoys roller skating and weight training. Let X represent the number of hours he spends roller skating weekly,

umka21 [38]

Answer:

$\mathbf{\mu_S = 12 }$ ; $\text{Elroy can expect to roller skate and weight train, on average, 12 }$ $\text{hours in a typical week.}$

Step-by-step explanation:

Given that:

The mean $\mu_X = 5$

The mean $\mu_Y = 7$

Where;

$S= X+ Y$

$\mu_S = \mu _X + \mu_Y \\ \\ \mu_S = 5+7 \\ \\ \mu_S = 12$

Thus;

$\mathbf{\mu_S = 12 }$ ; $\text{ Elroy can expect to roller skate and weight train, on average, 12 }$ $\text{hours in a typical week.}$
