Answer:
26.28km further
Step-by-step explanation:
Step one:
given data
distance moved in a day= 29.2 meters
for 1000 days the glacier will move x meters
cross multiply
x=29.2*1000
x=29200m
x=29.2km
distance moved in a day= 29.2 meters
for 100 days the glacier will move x meters
cross multiply
x=29.2*100
x=2920
x=2920m
The difference in distance between 1000days and 100days is
=29200-2920
=26280
=26.28km
26.28km further
Answer: 4:5
Step-by-step explanation:Because if you split them into groups they would be 4 in a group of corn muffins and 5 in a group of blueberry muffins
If the equation is then the domain is the set of all real numbers.
We can replace x with any real number and compute to get some real number output for y. There are no division by zero restrictions to worry about, or issues with taking a square root of a negative number (since this isn't really a square root function).
The cube root of a negative number is negative. For example, because (-4)^3 = (-4)*(-4)*(-4) = -64.
In interval notation, the domain would be written as to indicate the entire real number line.

Answer:
p-value: 0.0367
Decision: Reject H₀
Step-by-step explanation:
Hello!
Hypothesis to test:
H₀:ρ₁-ρ₂=0
H₁:ρ₁-ρ₂>0
The statistic to use to test the difference between two population proportions is the approximation of Z
Z=<u> (^ρ₁-^ρ₂)-(ρ₁-ρ₂) </u> ≈N(0;1)
√ (<u>^ρ₁(1-^ρ₁))/n₁)+(^ρ₂(1-^ρ₂)/n₂))</u>
Z=<u> (0.28-0.15)-0 </u>= 1.79
√ (<u>0.28(1-0.28)/200)+(0.15(1-0.15)/300)</u>
p-value
Remember: The p-value is defined as the probability corresponding to the calculated statistic if possible under the null hypothesis (i.e. the probability of obtaining a value as extreme as the value of the statistic under the null hypothesis).
P(Z>1.79)= 0.0367
Conclusion:
Comparing the p-value against the significance level, you can decide to reject the null hypothesis.
I hope you have a SUPER day!
