Answer:
Question 6 answer is 35
Step-by-step explanation:
using pythagoras theorem, hypotenuse²= opposite²+ adjacent²
since it is said that we're looking for the hypotenuse then the values given are for opposite and adjacent.
therefore, hyp²= 21²+28²
hyp²= 1225 take square root of both sides to eliminate square and find hypotenuse
hyp= 35
You have 4 options:
4 cards: because you draw cards and don't replace them your chance p changes on every trial, so it can't be a binomial experiment
roll 2 dice until...: a binomial experiment must have a consistent amount of trials, by doing an action until some condition is fulfilled violates this as the amount of trials or throws in this case is random
ask 9 people: there are three options, binomial experiments can only have 2
the only option left is the spinner, which is a binomial experiment
To find f(-7), just plug -7 in for all x
2(-7) + 8
-14 + 8
-6 is the answer!
Answers:
<h3>1. -5</h3><h3>2. 7</h3><h3>3. 1</h3><h3>4. 5</h3>
Step-by-step explanation:
Plug in the x into the equation and solve.
<h3>Value 1: X = 5</h3>
Y = -2(5) + 5
Y = -10 + 5
Y = -5
<h3>Value 2: X = -1</h3>
Y = -2(-1) + 5
Y = 2 + 5
Y = 7
<h3>Value 3: X = 2</h3>
Y = -2(2) + 5
Y = -4 + 5
Y = 1
<h3>Value 4: X = 0</h3>
Y = -2(0) + 5
Y = 0 + 5
Y = 5
I'm always happy to help :)
The temperature is 3 degrees less then it was at lunchtime when he went to bed you didn’t ask a question or explain it so I’m assuming this is what you meant
