Answer:

Answer: Option A.

Step-by-step explanation:

Hey there!

Here,

One angle measure is 35°.

Now,

35°+ angle 5= 180° { being linear pair}.

Angle 5 = 180° - 35°

Therefore the measure of angle 5 is 145°.

Angle 5 = angle 3 {alternate angle }.

Therefore the measure of angle 3 is 145°.

Hope it helps..

vladimir2022 [97]

Given:

The given function is $f(x)=4x^2+2x+6$

We need to determine the value of the discriminant f and also to determine the distinct real number zeros of f.

Discriminant:

The discriminant can be determined using the formula,

$\Delta = b^2-4ac$

Now, we shall determine the discriminant of the function $f(x)=4x^2+2x+6$

Substituting the values in the formula, we have;

$\Delta=(2)^2-4(4)(6)$

$\Delta=4-96$

$\Delta=-92$

Thus, the value of the discriminant of f is -92.

Distinct roots:

The distinct zeros of the function f can be determined by

(1) If $\Delta>0$ , then the function has 2 real roots.

(2) If $\Delta=0$ , then the function has 2 real roots ( or one repeated root).

(3) If $\Delta$ , then the function has 2 imaginary roots (or no real roots).

Since, the discriminant is $\Delta=-92 \ < \ 0$ , then the function has no real roots or 2 imaginary roots.

Thus, the function has 2 imaginary roots.

Samples of rejuvenated mitochondria are mutated (defective) in 3% of cases. Suppose 15 samples are studied, and they can be cons

stiks02 [169]

Answer:

C) At most one sample is mutated

Step-by-step explanation:

If there are 15 samples, it means that 15 is the total (100%) of samples. Then, if we know that there is a chance that 3% are mutated, then we calculate the 3% of 15:

$Mutated= \frac{3. 15}{100} = 0.45$

This means that at most one sample is mutated, as this result is not zero (we discard answer A), and 0.45 is not more than half of the samples.

The experimental probability of getting a multiple of 3 is $\frac{3}{8}$ .

Given that, Angelique throws a different six-sided dice 120 times.

<h3>What is Probability in maths?</h3>

Probability denotes the possibility of something happening. It's a field of mathematics that studies the probability of a random event occurring. From 0 to 1, the value is expressed. Probability is a mathematical concept that predicts how likely occurrences are to occur.

We know that, $Probability of an event=\frac{Number of favourable outcomes}{Total number of outcomes}$
