Answer:

q = -5 $\sqrt{5}$

q = 5 $\sqrt{5}$

Step-by-step explanation:

Since there is no constant value. This must be a special case.

So,

(q+5 $\sqrt{5}$ )(q-5 $\sqrt{5}$ )

q = -5 $\sqrt{5}$

q = 5 $\sqrt{5}$

Jasmine wants to use her savings of $1128 to buy video games and music CDs. The total price of the music CDs she bought was $72.

emmainna [20.7K]

First we subtract the cost of the music CDs from her savings 1,128 - 72 = 1,056. Next Jasmine wants to know how many video games she can buy with the remainder money. 1,056 ÷ 43 = 24 (rounded). Your answer is A. 24.

Hope this helps,

Answer: C

Step-by-step explanation:

Looking at the triangle, we see that the angles are the same. This tells us the triangle is an isosceles triangle. That means the two adjacent sides are equal to each other.

4x+23=10x-1 [subtract both sides by 4x]

23=6x-1 [add both sides by 1]

24=6x [divide both sides by 6]

x=4

Now, we know that x=4.

Can someone help me with this question?

Answer:

The required probability is 0.0155.

Step-by-step explanation:

We are given that the one-year survival rate for pancreatic cancer is 20%.

Of 12 people diagnosed with pancreatic cancer at one hospital, 6 survived one year.

The above situation can be represented through binomial distribution;

$P(X=r) = \binom{n}{r} \times p^{r} \times (1-p)^{n-r} ; x = 0,1,2,3,......$

where, n = number of trials (samples) taken = 12 people

r = number of success = 6 survived

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

one-year survival rate for pancreatic cancer, i.e; p = 20%

Let X = Number of people survived one year

So, X ~ Binom(n = 12 , p = 0.20)

Now, the probability that 6 survived one year is given by = P(X = 6)

P(X = 6) = $\binom{12}{6} \times 0.20^{6} \times (1-0.20)^{12-6}$

= $924 \times 0.20^{6} \times 0.80^{6}$

= 0.0155
