81/4
Step-by-step explanation:


9=4x/9
81=4×
x=81/4
adding logs means elements are multiplied, subtracting means divide. number in front of log is raised to power
base of log is raised to power of element after =
element in log is then equal to log base raised to power
solve resulting equation

Answer:
x=$7
Step-by-step explanation:
The total cost of bill is $32, $11 is from a plate of corn tacos. And there are 3 purchased burrito bowls at a cost of $x each.
$32 (total bill)
-$11 (tacos)
=$21
$21 / 3 (burrito bowls)
=$7
x<em> </em>or the cost of each burrito bowl is $7
The angle show with the yellow square has a measure of 90°.
Together with angles 1 and 2, they form a straight angle so we have:
∠1+∠2+90°=180°,
subtracting 90° from both sides we have:
∠1+∠2=90°
If the sum of the measures of 2 angles is 90°, the angles are called complementary.
Since the sum of the measures of angles 1 and 2 is 90°, then these 2 angles are complementary.
Answer: <span>They are complementary</span>
Answer:
The appropriate hypothesis set for Andraya to test is:


Step-by-step explanation:
The makers of the game claim that the wheel has an equally likely probability of landing on each section.
That is, the makers claim that the probability of earning the grand prize is:

Andraya has played the game for several months and believes that the grand prize occurs less often than the game makers claim.
At the null hypothesis, we test if it happens as often as the makers claim, that is, the proportion is 0.125. So

At the alternate hypothesis, we test if it happens less ofter than the makers claim, that is, the proportion is less than 0.125. So

The appropriate hypothesis set for Andraya to test is:
