In a certain game of chance, your chances of winning are 0.3. Assume outcomes are independent and that you will play the game fo

sergeinik [125]

Answer:

0.6517

Step-by-step explanation:

Given that in a certain game of chance, your chances of winning are 0.3.

We know that each game is independent of the other and hence probability of winning any game = 0.3 (constant)

Also there are only two outcomes

Let X be the number of games you win when you play 4 times

Then X is binomial with p = 0.3 and n =4

Required probability

= Probability that you win at most once

= $P(X\leq 1)\\=P(X=0)+P(X=1)$

We have as per binomial theorem

P(X=r) = $nCr p^r (1-p)^{n-r}$

Using the above the required prob

= 0.6517

Determine whether abc ----> jgh is a reflection, translation, rotation, or glide reflection.

Usimov [2.4K]

From this picture you can calculate coordinates of triangles' vertices:
$A(-9,0),\ B(-6,-4),\ C(-3,0),\ J(8,0),\ G(5,4),\ H(2,0)$ .

Since

$\frac{-9+8}{2} = \frac{-6+5}{2}= \frac{-3+2}{2}=- \frac{1}{2}$ $\frac{0+0}{2}= \frac{-4+4}{2} = \frac{0+0}{2} =0$

you can conclude that points A, B, C are rotated by $180^0$ about the point (-0.5,0) to form points J, G, H, respectively.

Answer: A is correct choice.

Jamie bought medicine priced at $180 she had to pay 5% sales tax and an additional 1.5% for handling fee how much money did she

alekssr [168]

Answer:

$191.70

Step-by-step explanation:

total amount spent = cost of medicine + cost of tax + cost of shipping

cost of tax = 0.05 x $180 = $9

cost of shipping 0.015 x $180 = $2.70

total cost = $180 + $9 + 2.70 = $191.70

What is the value of tan x°?

dmitriy555 [2]

Hi there!

$\tan(x) = \frac{opposite \: side}{adjecent \: side}$
$\tan(x) = \frac{8}{6}$
$\tan(x) = 1 \frac{1}{3}$

$x = 53.1$
Therefore tan x° = 1 1/3 and x = 53.1°
