Answer:

The value of x = 64. Hence, option A is correct.

Step-by-step Explanation:

\log _4\left(x\right)=3

We know that the rule:

y\:=\:\log _a\left(x\right)

can be represented as:

x\:=\:a^y

so

\log _4\left(x\right)=3

4³=x

x = 64

Thus, the value of x = 64. Hence, option A is correct.

I need help i don’t know how to do this
V125BC [204]

Answer:

EBGA

Step-by-step explanation:

The triangle is isosceles (XZ = YZ), so the base angles are congruent.  The total of all three angles in the triangle is 180 degrees, so subtracting out 52 leaves 128 degrees for the two base angles together.  Each base angles measures half of that, so m\angle 1 = 64^\circ, code E.

Look at vertex Y.  The big angle there also measures 64 degrees.

m\angle 2 + 31^\circ =64^\circ\\m\angle 2= 64^\circ - 31^\circ = 33^\circ \text{ (code B)}

Angle 3 is a vertical angle with the 88 degree angle, so its measure is also 88 degrees (code G).

Finally, angle 4 is an exterior angle in the small triangle that contains angles 2 and 3.  In that triangle, angles 2 and 3 are the remote interior angles.

m\angle 4 = m\angle 2 + m\angle 3\\m\angle 4 = 33^\circ + 88^\circ = 121^\circ \text{  (code A)}

Appended below is the code for Selection Sort. You really do not have to understand the details of the code. If this algorithm t
kramer

Answer:

12 seconds.

Step-by-step explanation:

Let t represent time taken by code to sort an array of 24 elements.

We have been given that an algorithm takes 4 seconds to sort an array of 8 elements. We are asked to find the time it will take for same code to sort an array of 24 elements.

We will use proportions to solve our given problem.    

\frac{\text{Time}}{\text{Array of elements}}=\frac{4}{8}

\frac{t}{24}=\frac{4}{8}

\frac{t}{24}\cdot 24=\frac{4}{8}\cdot 24

t=\frac{4}{1}\cdot 3

t=12

Therefore, it will take 12 seconds for the same code to sort an array of 24 elements.

What's the probability you will flip 3 coins in a row and they all land on HEADS?
liberstina [14]

Answer:

B. 1/8 chance

Step-by-step explanation:

Every time you flip a coin you have a 1/2 probability of landing on heads.

If you repeated the process three times in the row

It would be 1/2 x 1/2 x 1/2 = 1/8

The odds they all land on heads is 1/8
