Answer:

g = vt/(v - t)

Step-by-step explanation:

See the solution in steps:

1/t = 1/g + 1/v
1/g = 1/t - 1/v
1/g = (v - t)/(vt)
g = vt/(v - t)

Describe in words how you would solve the linear system y = 3x + 1 and y = - 2x + 3.

disa [49]

Answer:

Below.

Step-by-step explanation:

As both the right sides of the 2 equations are equal to y, by the transitive law of equality 3x + 1 = -2x + 3.

W then solve this equation for x then substitute this value of x in the first equation ( y = 3x + 1) to find the value of y.

A baseball player has a batting average of 0.25. What is the probability that he has exactly 2 hits in his next 7 at bats

marissa [1.9K]

Answer:

The probability that he has exactly 2 hits in his next 7 at-bats is 0.3115.

Step-by-step explanation:

We are given that a baseball player has a batting average of 0.25 and we have to find the probability that he has exactly 2 hits in his next 7 at-bats.

Let X = Number of hits made by a baseball player

The above situation can be represented through binomial distribution;

$P(X = r) = \binom{n}{r}\times p^{r} \times (1-p)^{n-r}; x = 0,1,2,......$

where, n = number of trials (samples) taken = 7 at-bats

r = number of success = exactly 2 hits

p = probability of success which in our question is batting average

of a baseball player, i.e; p = 0.25

SO, X ~ Binom(n = 7, p = 0.25)

Now, the probability that he has exactly 2 hits in his next 7 at-bats is given by = P(X = 2)

P(X = 2) = $\binom{7}{2}\times 0.25^{2} \times (1-0.25)^{7-2}$

= $21 \times 0.25^{2} \times 0.75^{5}$

= 0.3115

Simplify the expression x^2 + 3x + 4

Leni [432]

Answer:

( x + 4 ) × ( x − 1 )

Step-by-step explanation:

The equation in the A x ² + B x + C

The C is negative which indicates that one binomial will be negative and one binomial will be positive. The B is positive which indicates that the positive binomial will be larger than the negative binomial . The B is +3 which tells that the difference in the two factors is 3
