Answer:
16.00 cm
Step-by-step explanation:
r = 13 m,
Surface area A = 2πrh + 2πr² = 2πr (h + r)
2,285.92 =2*3.14*13 (13 + h)
2,285.92 = 81.64 (13 + h)
13 + h = 2,285.92/81.64 = 28.00
so h = 28.00 - 12 = 16.00 cm

You run a local bakery. You know from experience that muffin sales can be represented by a normal distribution with mean 40 and standard deviation 6. Today you bake 34 muffins. What is the probability you run out of muffins today?
The is a probability of 15.87% that if you bake 34 muffins it would run out of today.
What is z scoreZ score is used to determine by how many standard deviations the raw score is above or below the mean. It is given by:
z = (x - μ) / σ
Where x = raw score, μ = mean and σ = standard deviation.
Given that σ = 6, μ = 40, hence:
For x = 34:
z = (34 - 40)/6 = -1
P(z < -1) = 0.1587
The is a probability of 15.87% that if you bake 34 muffins it would run out of today.

The total amount that Mrs. Chauke paid for buying airtime using her bank's services sum up to R2.20. This question is about Analyzing Bank Statements.
Step 1:
Notice that on the 23rd of March and the 24th of March. On both occasions, she was charged R1.10 each.
Step 2:Hence, to get the total amount she paid as charges for buying airtime, we say:
1.10 + 1.10 = R2.20

The serum cholesterol levels for men in one age group are normally distributed with a mean of 178.1 and a standard deviation of 40.7. (All units are in mg/100mL). Find the two levels that separate the top 9% and the bottom 9%.
Please explain!
Answer:
the levels are 123.5 and 232.7 mg/mL
Step-by-step explanation:
The inverse normal function is used to find limit values from an area (probability).
Your calculator can show these values to you. (see attached)
The top 9% are above 232.7 mg/mL.
The bottom 9% are below 123.5 mg/mL.
__
A suitable calculator can evaluate the inverse normal function to find the x-value corresponding to some area, mean, and standard deviation. For the level that separates the bottom 9% from the rest of the area, we use an area value of 0.09. The mean and standard deviation values are those provided in the problem statement.
For the level that separates the top 9% from the rest of the area, we use an area value of 1 -0.09 = 0.91.
__
The second attachment shows an online calculator that can give the limits on the middle 0.91 -0.09 = 0.82 of the area under the probability curve.
_____
Additional comment
An app version of an approximation to a TI-Nspire calculator is shown in the first attachment. The invNorm function is found at the Distr key (2nd VARS).
For the top 9% we have to find the value x for which
P(X<x) = 0.91
Converted to the standard normal distribution this corresponds to
P(Z<(x-178.1)/40.7) = 0.91
Then: (x-178.1)/40.7 = 1.341
or x = 232.7
For the bottom 9% we have to find the value x for which
P(X<x) = 0.09
Converted to the standard normal distribution this corresponds to
P(Z<(x-178.1)/40.7) = 0.09
Then: (x-178.1)/40.7 = -1.341
or x = 123.5
So the 2 levels that separate the top 9% and the bottom 9% are 232.7 and 123.5.

1. Prove the following trig identity
tan(x/2)=sinx/1+cosx
Step-by-step explanation:
[tex] \tan( \frac{x}{2} ) = \frac{ \sin(x) }{1 + \cos(x) } [/tex]
[tex] \tan( \frac{x}{2} ) = \frac{ \sqrt{1 - \cos(x) } }{ \sqrt{1 + \cos(x) } } [/tex]
So we have
[tex] \frac{ \sqrt{1 - \cos(x) } }{ \sqrt{1 + \cos(x) } } = \frac{ \sin(x) }{ \sqrt{1 + \cos(x) } } [/tex]
Next, we then rationalize the numerator so we get
[tex] \frac{ \sqrt{1 - \cos(x) } }{ \sqrt{1 + \cos(x) } } \frac{ \sqrt{1 + \cos(x) } }{1 + \cos(x) } = \frac{ \sin(x) }{ {1 + \cos(x) } } [/tex]
The denominator should be square root so to let you know .
So know we ahev
[tex] \frac{ \sqrt{1 - \cos {}^{2} (x) } }{1 + \cos(x) } = \frac{ \sin(x) }{1 + \cos(x) } [/tex]
[tex] \frac{ \sqrt{ \sin {}^{2} (x) } }{1 + \cos(x) } = \frac{ \sin(x) }{ {1 + \cos(x) } } [/tex]
[tex] \frac{ \sin(x) }{1 + \cos(x) } = \frac{ \sin(x) ) }{1 + \cos(x) } [/tex]
Brain invests £2500 into his bank account he receives 2.5% per year simple interest how much will Brian have after 5 years give your answer to the nearest penny where appropriate
Answer:
Step-by-step explanation:
Rate of interest = r = 2.5%
The amount invested = P = £ 2500
Number of years = n = 5 years
[tex]Simple \ Interest = P*r*t[/tex]
[tex]=2500*\dfrac{2.5}{100}*5\\\\\\= 25 * 2.5*5[/tex]
= £ 312.5
Amount that Brain will have after 5 years = P + simple interest
= 2500 + 312.5
= £2812.50

Four friends go to the movies and pay $11 per ticket. They also each buy a snack
combo. If they spent a total of $76, how much did each snack combo cost?
Answer:
Each snack combo costed $8
Step-by-step explanation:
4 friends* 11 per ticket = $44 for four tickets
76 - 44 = $32 spent on all the snack combos
$32 ÷ 4 friends = $8 spent on each snack combo
So, each snack combo costed $8

Find the volume of a right circular cone that has a height of 11.2m and a base with a diameter of 8.8.
227.1 m³
Explanation:
[tex]\sf \ formula \ of \ volume \ of \ cone \ \ : \dfrac{1}{3} \ \pi \ r^2 \ h[/tex]
[tex]\sf \hookrightarrow \dfrac{1}{3} \pi (4.4)^2 (11.2)[/tex]
[tex]\sf \hookrightarrow \dfrac{1}{3} \pi (216.832)[/tex]
[tex]\sf \hookrightarrow 72.3 \pi \ m^3[/tex]
[tex]\sf \hookrightarrow 227.066 \ m^3[/tex]
[tex]\sf \hookrightarrow 227.1 \ m^3[/tex]
Solution:
We know that:
[tex]Volume \ of \ cone = \pi r^{2} \frac{h}{3} \\\\ Height = 11.2 \ m\\\\ Diameter = 8.8[/tex]
Step-1: Find the radius of the cone.
[tex]Diameter = 2(Radius) \\\\ 8.8 \ m = 2(Radius) \\\\ \frac{8.8}{2} = \frac{2(Radius)}{2} \\\\ 4.4 \ m = Radius[/tex]
Step-2: Substitute the radius and the height in the formula.
[tex]Volume \ of \ cone = \pi r^{2} \frac{h}{3} \\\\ Volume \ of \ cone = (3.14)( 4.4^{2})( \frac{11.2}{3})\\\\ Volume\ of \ cone = (3.14)(19.36)( \frac{11.2}{3}) \\\\ Volume \ of \ cone = \frac{680.85}{3} = \bold{226.95 = 227 \ m^{3} \ (Rounded)}[/tex]
Thus, the volume of the cone is about 227 m³.

Do you perhaps have a pic of the triangle they are talking about?
Solve the triangle, AMDM
Answer:
B
Step-by-step explanation:
You are given two sides and the included angle, so you need to use the law of cosines.
c² = a² + b² - 2ab cos C
c² = 12² + 13² - 2(12)(13)cos 134°
c² = 313 - 312(-0.6947)
c² = 529.733
c = 23.016
Now use the law of sines.
c/sin C = a/sin A
23.016/sin 134° = 12/sin A
sin A = 12 × sin 134° / 23.016
sin A = 0.37504
A = 22.03°
B = 180° - 134° - 22.03°
B = 23.97°
m<A = 22°; m<B = 24°; c = 23 km
Answer: B
