Find x on this triangle

blsea [12.9K]

Answer:

3 sqrt(3) =x

Step-by-step explanation:

Since this is a right triangle, we can use trig functions

cos theta = adj / hyp

cos 30 = x/6

6 cos 30 = x

6 ( sqrt(3)/2) = x

3 sqrt(3) =x

Peter works as a delivery person for a bike shipping company. The graph shows a linear model for his delivery times on different

aev [14]

Answer/Step-by-step explanation:

✍️The equation of the line in point-slope form:

The equation is given as $y - b = m(x - a)$ , where,

(a, b) = a point on the line.

$slope (m) = \frac{y_2 - y_1}{x_2 - x_1}$

Let's find the slope (m) of the line, housing (3, 21) and (6, 12):

$slope (m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{12 - 21}{6 - 3} = \frac{-9}{3} = -3$

Substitute a = 3 and b = 21, m = -3 into $y - b = m(x - a)$ .

Thus, the point-slope equation would be:

✅ $y - 21 = -3(x - 3)$

✍️The equation of the line in slope-intercept form:

Rewrite $y - 21 = -3(x - 3)$ , so that y is made the subject of the formula.

$y - 21 = -3x + 9$

Add 21 to both sides

$y = -3x + 9 + 21$

$y = -3x + 30$

✅The slope-intercept equation of the line is $y = -3x + 30$

Where,

-3 = how much did his delivery time decrease per day (slope)

30 = how long it initially took Peter to deliver his packages (y-intercept)

If the probability that the Islanders will beat the Rangers in a game is 2/7, what is the probability that the Islanders will wi

Helga [31]

0.1328 is the probability that the Islanders will win exactly zero out of six games in a series against the Rangers.

<u>Step-by-step explanation:</u>

Given data is that probability the islanders will beat the rangers in a game is $\frac{2}{7}$ .

So, probability that the islanders will not beat the rangers in the game is = $1-\frac{2}{7}=\frac{5}{7}$

Let, x be the favorable outcome as,

x = no. of times islanders win the game

Probability of success (p) = $\frac{2}{7}$

Probability of failure (q) = $\frac{5}{7}$

So, the probability of x would be,

$x = n C_{r} \times(p)^{r} \times(q)^{n-r}$

$P(x=0) = 6 C_{0} \times\left(\frac{2}{7}\right)^{0} \times\left(\frac{5}{7}\right)^{6}$

$P(x=0) = 1 \times 1 \times \frac{(15625)}{117649} = 0.13281$
