Answer:

30 minutes

Step-by-step explanation:

he ran 45 minutes in 6 miles which is 45 min/6 miles or 45/6 (divide) = 7.5 min/ 1 mile. 7.5×4 miles = 30 min

Does the system have no solution?

kvv77 [185]

Answer:

$\mathrm{A)\:}-6$

Step-by-step explanation:

Notice that in the second equation, the coefficient of $y$ is $2$ times greater than in the first. Therefore, by making the coefficient of $x$ in the second equation $2$ times greater than in the first, it's impossible to only isolate one variable.

Therefore, when $a=-3\cdot 2=\fbox{-6}$ , there are no solutions to this system.

Can some please answer this

Sonbull [250]

Answer:

B (2 violet)

Step-by-step explanation:

Let the colors be represented by their first letter. Then the balances give rise to two equation:

o +y +b +v = r +g +b

o +y +v = g +v

Subtracting the second equation from the first gives ...

(o +y +b +v) -(o +y +v) = (r +g +b) -(g +v)

b = r +b -v

Adding v-b to both sides, we have ...

b +(v -b) = r +b -v +(v -b)

v = r

Multiplying this result by 2, we can match the final balance:

2r = 2v . . . . . . . choice B

4 hours to pay the same amount

and aif you want a 3 hours work you should get carpenter A

Step-by-step explanation:

$50x = 20 + 45x \\ 5x = 20 \\ x = 4hours \\$

carpenter A for 3 hours:

$50 \times 3 = 150dollars \\$

carpenter B for 3 hours:

$20 + 45 \times 3 = 155dollars$

1. The probability of telesales representative making a sale on a customer call is 0.15.

Mumz [18]

Answer:

$n = 33$

$n = 19$

Step-by-step explanation:

From the question we are told that

The probability of telesales representative making a sale on a customer call is $p = 0.15$

The mean is $\mu = 5$

Generally the distribution of sales call made by a telesales representative follows a binomial distribution

i.e

$X \~ \ \ \ B(n , p)$

and the probability distribution function for binomial distribution is

$P(X = x) = ^{n}C_x * p^x * (1- p)^{n-x}$

Here C stands for combination hence we are going to be making use of the combination function in our calculators

Generally the mean is mathematically represented as

$\mu = n* p$

=> $5= n * 0.15$

=> $n = 33$

Generally the least number of calls that need to be made by a representative for the probability of at least 1 sale to exceed 0.95 is mathematically represented as

$P( X \ge 1) = 1 - P( X < 1 ) > 0.95$
