<span>x = {-4, 4}
</span>
<span>Divide each side by '5'.
x2 = 16
Simplifying
x2 = 16
Take the square root of each side:
x = {-4, 4}</span>
No.
This is because the y value of 1 repeats itself, which never happens in an exponential function. This function is likely quadratic, which forms a parabola.
Answer:
z= 2.38
P = 0.008656
Step-by-step explanation:
Here n= 500 and p~= 464/500= 0.928 and q`= 1- 0.928 = 0.072
We formulate our null and alternate hypothesis as
H0 = 0.9 ; H0 > 0.9
The degree of confidence = 90%
z₀.₀₅ = 1.645 for α= 0.05
We use the test statistic
z= x- np/√npq
z= 466-500 *0.9/ √500 * 0.9(1-0.9)
z= 466- 450/ √45
z= 16/6.7082
z= 2.38
As the calculated value of z= 2.38 is greater than α =1.645 so we reject H0.
If H0 is true the P value is calculated as
P = 1- Ф( 2.38)
P = 1-0.991344=0.008656
Answer:
The answer to this question would be 11 :)
Answer:
Step-by-step explanation: I'm assuming this problem says 56 divided by 7 times 2 in the numerator; OVER 4 to the second power in the denominator. First step would be to multiply 7 times 2, giving you 14. Thus u have 56 divided 14, which is 4. In the denominator, it says 4 to the second power, which is 16. Now u have 4 OVER 16. Now we will reduce the fraction. Both numerator and denominator have a GCF of 4. So we divide top and bottom number by 4. The end result is 1 OVER 4.
