Find the value of x for the given value of y. y=x4−7; y=2

y=x4−7; y=2

Y=2 (2)=x.4-7

2+4x-7

4x-7=2  get the variable alone by doing the same thing to both sides

4x=9

4x/4=9/4

y=9/4

x=9/4

step-by-step explanation:

add 6% to the value she got from selling the house.

d. 24+-0.114

step-by-step explanation:

the question requires us to calculate the approximate 95% confidence interval for the mean number of ounces of ketchup per bottle in the sample given the following statistics;

sample mean = 24

standard deviation, σ = 0.4

sample size , n = 49

the confidence interval for a population mean is calculated using the formula;

sample mean ± z-score*(σ/sqrt(n))

the z-score associated with a 95% confidence interval, from the standard normal tables, is;

1.96

substituting these values into the formula;

24 ± 1.96*(0.4/7)

= 24 ± 0.112

from the alternatives given, choice d is closest to the above expression;
