Answer:
Step-by-step explanation:
Sample mean x bar = 98.9
Std dev s = 0.62
Sample size n = 106
Std error =
Since population std deviation not known we can use t critical value.
t critical for 99% with df = 105 is 1.98
Margin of error = ±1.98(0.0602) =±0.1192
Confidence interval for sample mean = (98.9±0.1192)
=(98.781, 99.019)
2) Sample mean confidence interval suggests that sample mean is different from the population since 98.6 is not contained in the confidence interval.
3) Population interval confidence mean would be
98.6±0.1192
=(98.4808, 98.7192)
Answer:
58.5 ft²
Step-by-step explanation:
The figure is made up of a square, triangle and rectangle. Thus, the area of the figure is the sum of the areas of the square, triangle and rectangle.
Let's find the area of each!
<u>Square</u>
Area of square= side ×side
Area
= 3(3)
= 9 ft²
<u>Triangle</u>
Area of triangle= ½ ×base ×height
Base= 11 ft
Height= 3 ft
Area
= ½(11)(3)
= 16.5 ft²
<u>Rectangle</u>
Area of rectangle= length ×breadth
Area
= 3(11)
= 33 ft²
Area of figure
= 9 +16.5 +33
=
Answer:
The correct option is C. The function is a stretch of an exponential decay function.
Step-by-step explanation:
The general form of an exponential function is
where, a is the initial value and b is the growth factor.
If b<1, then it represents a decay function and if b>1, then it represents a growth function.
Let k be a stretch and compression factor.
If k<1, then it represents vertical compression and if k>1, then it represents vertical stretch.
In third function
Therefore the function is a stretch of an exponential decay function.
Answer:
The answer is -2
Step-by-step explanation:
you subtract common numbers, so:
5s - 3s = 2s
Then,
-6 + 2 = -4
You would then get
2s - 4
divide -4 by 2 which is -2
and your answer is s = -2
1 doZen = 12 so 12 *3 is 36 therefore Sara has 36 golf balls
