Annual Rainfall for Albany (in.) 23.36 18.51 28.54 22.36 30.50 24.74 11.93 15.34 18.07 15.98 Annual Rainfall for Zachary (in.) 27.27 20.11 31.14 25.88 32.97 25.03 18.55 23.91 22.75 19.73 Find the mean for the two cities' annual rainfalls. In which city does it rain more in a year, on average? Drag and drop the correct choices into the boxes to complete the statement. On average, Albany gets _ inches of rain per year and Zachary gets _ inches of rain per year. on average, which city rains more zachary or albany?
Answers
Answer:
On average, Albani gets 20.933 inches of rain per year.
On average, Zachary gets 24.734 inches of rain per year.
On average, Zachary gets more rain than Albani.
Step-by-step explanation:
Mean is given by:
[tex]Mean = \frac{Sum}{Total}[/tex]
For Albani :
Sum of total number of terms = 23.36+18.51+28.54+22.36+30.50+24.74+11.93+15.34+18.07+15.98
Sum of total number of terms = 209.33
Number of terms = 10
[tex]Mean=\frac{209.33}{10}\\\\Mean=20.933\\[/tex]
For Zachary :
Sum of total number of terms = 27.27+20.11+31.14+25.88+32.97+25.03+18.55+23.91+22.75+19.73
Sum of total number of terms = 247.34
Number of terms = 10
[tex]Mean=\frac{247.34}{10}\\Mean=24.734[/tex]

Answer: [tex]\dfrac{1}{8}[/tex]
Step-by-step explanation:
Formula : Probability = [tex]\dfrac{\text{favorable outcomes}}{\text{total outcomes}}[/tex]
Given , Sam has 4 cards numbered 2,3,5, and 7.
His friend has 4 cards numbered 1,2,6 and 7.
If they both draw one card and put that on table , then the possible combinations of cards would be (2,1) , (2,2), .... (7,6), (7,7).
i.e. Number of possible outcomes would be (S) 4 x 4 = 16
Favorable outcomes that they will choose same number (F) = (2,2) , (7,7)
Now , the probability that they will both choose the same number would be :
[tex]\dfrac{F}{S}=\dfrac{2}{16}=\dfrac{1}{8}[/tex]
Hence, the required probability = [tex]\dfrac{1}{8}[/tex]
What is the measure of angle c in degrees? *

Answers
Answer:
Option (2)
Step-by-step explanation:
Measure of angle formed by two tangents from a point outside the circleis half the difference of the measures of the intercepted arcs.
From the figure attached,
m∠C = [tex]\frac{1}{2}[m(\text{major arc AB})-m(\text{minor arc AB)}][/tex]
= [tex]\frac{1}{2}[(360-m\widehat{AB})-m(\widehat{AB})][/tex]
= [tex]\frac{1}{2}[360-2m(\widehat{AB})][/tex]
= [tex]180-m\widehat{AB}[/tex]
= 180 - 150
= 30°
Therefore, measure of angle C will be 30°.

Answer:
Option B, C and E are supplementary angles.
Step-by-step explanation:
We need to find supplementary angles.
Supplementary angles are those angles who sum up to 180 °.
I have attached picture for reference.
Looking at the figure given:
We have supplementary angles:
∠4 and ∠3
∠4 and ∠5
∠5 and ∠6
∠7 and ∠8
∠3 and ∠6
But the options given are: ∠4 and ∠3,∠4 and ∠5, ∠3 and ∠6
So, Option B, C and E are supplementary angles.
Supplementary angles are pair of adjacent angles that add up to 180 degrees
Conditions for supplementary anglesFor a pair of angles to be supplementary, then the following must be true
The angles must be adjacent i.e. side by sideThe angles must add up to 180 degreesThe image is not given.
So, I provided a general explanation

When dividing complex numbers, why do
you need to multiply the numerator and
denominator by the complex conjugate of the
denominator?
Answers
Answer:
Hope this helps..
Step-by-step explanation:
So when you need to divide one complex number by another, you multiply the numerator and denominator of the problem by the conjugate of the denominator. This step creates a real number in the denominator of the answer, which allows you to write the answer in the standard form of a complex number.
Answer:
You have to multiply by the complex conjugate because the denominator has to be a real number. By multiplying the complex conjugate you can transform the denominator in to a real number.

Answers
Answer:
Height = 8cm
Step-by-step explanation:
I hope it helps
The required height of the cylinder is 8cm.
A cylinder of base radius 4cm. The ratio of the area of it's base to that of it's curved surface area is 1:4. Height of cylinder is to be determine.
Surface area is defined as the area of the surface that are uncovered.
Here,
area of circle/surface area of cylinder=1/4
πr²/2πrh=1/4
r/2h=1/4
h=2r
where r = 4cm
h = 2*4
h = 8cm
Thus, the required height of the cylinder is 8cm.

(q^4)^z=q^12
find the value of z
Answers
Answer:
z = 3
Step-by-step explanation:
Using the rule of exponents
[tex](a^{m}) ^{n}[/tex] = [tex]a^{mn}[/tex]
Thus
[tex](q^{4}) ^{z}[/tex] = [tex]q^{4z}[/tex] , so
[tex]q^{4z}[/tex] = [tex]q^{12}[/tex]
Since the bases on both sides are equal then equate the exponents
4z = 12 ( divide both sides by 4 )
z = 3
Answer:
The value of z is 3.
Step-by-step explanation:
You have to use Indices Law,
[tex] {( {a}^{m}) }^{n} \: ⇒ \: {a}^{mn} [/tex]
So for this question, first you have to get rid of brackets :
[tex] { ({q}^{4} )}^{z} = {q}^{12} [/tex]
[tex] {q}^{4z} = {q}^{12} [/tex]
Next you can solve it since both have the same bases :
[tex] {q}^{4z} = {q}^{12} [/tex]
[tex]4z = 12[/tex]
[tex]z = 3[/tex]
