Answer:

3: 2q − 4 = 20

Step-by-step explanation:

Solve for q:

2 q - 4 = 20

Add 4 to both sides:

2 q + (4 - 4) = 4 + 20

4 - 4 = 0:

2 q = 20 + 4

20 + 4 = 24:

2 q = 24

Divide both sides of 2 q = 24 by 2:

(2 q)/2 = 24/2

2/2 = 1:

q = 24/2

The gcd of 24 and 2 is 2, so 24/2 = (2×12)/(2×1) = 2/2×12 = 12:

Answer:  q = 12

El volumen de un cubo, cuyos lados miden 4,5 cm corresponde a: A- 91 cm2 B- 91,1 cm C- 91 cm3
Leya [2.2K]

Answer:

La respuesta correcta es la opción C: 91 cm³.

Step-by-step explanation:

La fórmula del volumen de un cubo es la siguiente:

V = a^{3}

En dónde:

a: es cada lado del cubo = 4,5 cm

Entonces, el volumen del cubo es:

V = a^{3} = (4,5 cm)^{3} = 91.1 cm^{3} \approx 91 cm^{3}

Por lo tanto, la respuesta correcta es la opción C: 91 cm³.

Seventy percent of kids who visit a doctor have a fever and 21% of kids have fever and sore throats . what is the probability th
Neko [114]

The probability that a kid who goes to the doctor has a sore throat given that he has a fever is <u>0.30 or 30%</u>. Computed using conditional probability.

The probability of any event A given that event B has already taken place is found using the formula P(A|B) = P(A ∩ B)/P(B). This is known as conditional probability, where P(A ∩ B) is the probability of events A and B, and P(B) is the probability of event B.

In the question, we are given that 70% of kids who visit a doctor have a fever and 21% of kids have a fever and sore throats.

We are asked to find the probability that a kid who goes to the doctor has a sore throat given that he has a fever.

We suppose the event of going to the doctor while having a fever to be B, and going to a doctor while having a sore throat to be A.

We are given that 70% of kids who visit a doctor have a fever, that is, the probability of event B, P(B) = 70% = 0.7.

We are given that 21% of kids who visit a doctor have a fever and sore throats, that is, the probability of event A and event B, P(A ∩ B) = 21% = 0.21.

We are asked to find the probability that a kid who goes to the doctor has a sore throat given that he has a fever, that is, we are asked to find the conditional probability of event A, when event B has already taken place, that is, P(A|B).

By formula, we know that:

P(A|B) = P(A ∩ B)/P(B) = 0.21/0.70 = 0.30.

Thus, the probability that a kid who goes to the doctor has a sore throat given that he has a fever is <u>0.30 or 30%</u>.

If <img src="https://tex.z-dn.net/?f=%283x%2B5%29%5E2%3Dax%5E2%2Bbx%2Bc" id="TexFormula1" title="(3x+5)^2=ax^2+bx+c" alt="(3x+5)
Vinvika [58]

Answer:

64

Step-by-step explanation:

(3x+5)^2 = ax^2 +bx+c

FOIL the left side

(3x+5) (3x+5)

9x^2 +15x+15x+25

Combine like terms

9x^2 +30x+25

a=9

b= 30

c= 25

a+b+c = 9+30+25 = 64
