Answer:

Step-by-step explanation:
In this problem, we are given expression in exponent form and we have to simplify the expression.
The expression is
Now, we know that
So,
Now, 500 can be written as 100 × 5 = 10² × 5
Therefore,
{Since 500 = 100 × 5 = 10² × 5} (Answer)
Answer:
B. 20
Step-by-step explanation:
Cos a = b/c
Cos 53° = b/25
b = 25 × 0,6 = 15
x = √(25² - 15²)
x = √(625 - 225)
x = √400
x = 20
Answer:
i dunno
Step-by-step explanation:
Answer: B) 73
Step-by-step explanation:
Complementary angles are 2 angles which add up to 90.
90 - 17 = 73
Answer:
the statements given above are true.
Step-by-step explanation:
Given that Frederick designed an experiment in which he spun a spinner 20 times and recorded the results of each spin.
He spun a 4 five times.
The statements true are:
i) For the experimental outcomes to be closer to the predicted outcome, the number of trials should be increased.
iii) If the number of trials is changed, the experimental probability also changes.
iv) If the number of trials is changed, the predicted number of outcomes also changes.
v) If the number of trials is changed, the number of experimental outcomes also changes.
