°Alternate interior angles are equal
°Corresponding angles are equal
°Vertically opposite angles are equal
°Angles on the same side of tranversal are supplementary

Alternate exterior angles two angles in the exterior of the parallel lines, and on opposite (alternate) sides of the transversal. Alternate exterior angles are non-adjacent and congruent. Corresponding angles two angles, one in the interior and one in the exterior, that are on the same side of the transversal.

If represents the number of bacteria in a culture at time t, how many will there be at time

Crazy boy [7]

Answer:

Population of bacteria at time $t = 6$ is $2441$

Step-by-step explanation:

The complete question is

If $y = 10 (2.5)^t$ represents the number of bacteria in a culture at time t, how many will there be at time $t = 6$

Solution

Given

The population of bacteria after time t is equal to $y = 10 (2.5)^t$

Population when at time $t = 6$

We will substitute the value of time in above equation.

$y = 10 (2.5)^6\\y = 10 *244.14\\y = 2441.4 = 2441$

Consider a triangle ABC like the one below. Suppose that a =53, b=18, and A=130º. (The figure is not drawn to scale.) Solve the

ddd [48]

Answer:

B = 15.1°, C = 34.9°, c = 39.6

Step-by-step explanation:

law of sines

53/sin 130 = 18/sin B

sin B = .26; B = 15.1°

C = 180 - 15.1 - 130 = 34.9°

c/sin 34.9 = 53/sin 130

c = 39.6

Answer:

b. Because the probability of being 15 or more correct is 0.0207, it is likely that she is just guessing at the questions.

Step-by-step explanation:

-This is a binomial probability distribution with p=0.5, n=20 and x=15.

The function is expressed as:

$P(X=x)={n\choose x}p^x(1-p)^{n-x}$

We calculate the probability of guessing 15 or more correctly:

$P(X\geq 15)=1-P(X$

The probability of passing, guessing 15+ correctly, is 0.0207. This probability is very low and it is it is likely that she is just guessing at the questions
