Answer:
the probability of a coin landing on heads 3 times in a row is 1/8 or 0.125 or 12.5%
Step-by-step explanation:
the chance of landing heads once is 1/2, for it to be 2 times in a row its 1/4, and 3 times in a row its 1/8, basically every time you want to do it in a row you multiply 1/2, so for example for this question you multiply 1/2 by however times you want the coin to land on heads in a row, (1/2) X(1/2)X(1/2)
Answer:
A.
Step-by-step explanation:
The negative gives a reflection in the x-axis.
The 2 is a vertical stretch factor 2.
Answer: V=60
Explanation-
The first step is to find the resistance in the current with 480 volts.
The equation for resistance is= voltage/current(amps)
So the equation would be: 480/12
Solve: 480/12=40 ohms
40 is the resistance
Now you will use this the answer the seconds part.
In the second part you are finding the voltage.
Equation for voltage: V= current x resistance
So the equation would be: 1.5 amps x 40 ohms
Solve: 1.5 x 40= 60 volts
Answer:
<em> 85% level of the confidence interval is</em>
<em>(26.337, 26.662)</em>
Step-by-step explanation:
<u><em>Explanation</em></u>:-
Given the size of the sample 'n' = 295
Mean of the sample x⁻ = 26.5
The Standard deviation of the Population = 2.7
85% level of the confidence interval is determined by

Critical value Z₀.₁₅ = 1.036
<em> 85% level of the confidence interval is determined by</em>


( 26.5 - 0.1628 , 26.5+0.1628)
(26.3372,26.6628)
