The radius of a circle is 16 cm. Find its area in terms of \piπ.
Answer:
2526.618
Step-by-step explanation:
To find the are of a circle you do r π²
So, 16 x π = 50.265, then 50.265² is 2526.618

Work out m and c for the line:2y−4x=2
Step-by-step explanation:
General equation : y = mx + c
2y - 4x = 2
2y = 4x + 2
y = 2x + 1
Therefore m = 2 and c = 1.

A bottling company uses a filling machine to fill plastic bottles with cola. The bottles are supposed are supposed to contain 300m. In fact, the contents vary according to a Normal Distribution with mean of 298 mL and a standard deviation of 3 mL. (a) What is the probability that an individual bottle contains less than 295 mL? Show your work. (b) What is the probability that the mean contents of six randomly chosen bottles is less than 295 mL? Show your work.
Answer:
0.15866 ; 0.0071627
Step-by-step explanation:
Given that:
Mean (m) = 298
Standard deviation (s) = 3
A.) P(x < 295)
Using the relation to obtain the standardized score (Z) :
Z = (x - m) / s
Z = (295 - 298) / 3 = - 1
p(Z < - 1) = 0.15866 ( Z probability calculator)
B.)
Z = (x - m) / s /sqrt(n)
Z = (295 - 298) / 3/sqrt(6) = −2.449489
p(Z < - 2.449) = 0.0071627 ( Z probability calculator)
Given values are:
Mean,
m = 298Standard deviation,
s = 3(a)
P(x < 295)
The standardized score will be:
→ [tex]Z = \frac{(x-m)}{s}[/tex]
By substituting the values, we get
[tex]= \frac{(295-298)}{3}[/tex]
[tex]= \frac{-3}{3}[/tex]
[tex]= -1[/tex]
Now,
By using the Z probability calculator, we get
→ [tex]p(Z< -1) = 0.15866[/tex]
(b)
The standardized score will be:
→ [tex]Z = \frac{x-m}{\frac{s}{\sqrt{n} } }[/tex]
By putting the values,
[tex]= \frac{295-298}{\frac{3}{\sqrt{6} } }[/tex]
[tex]= -2.449489[/tex]
Now,
→ [tex]p(Z < -2.449)= 0.007163[/tex]
Thus the responses above are correct.

Step-by-step explanation:
Given
[tex]\frac{3}{4}x - 5 = \frac{5}{6}[/tex]
Required
Rewrite to remove fractions
The denominators in the above expression are 4 and 6.
So, first we take the LCM of 4 and 6
[tex]LCM = 12[/tex]
Next, multiply both sides of the equation by this LCM (12)
[tex]12 ( \frac{3}{4}x - 5) = \frac{5}{6} * 12[/tex]
[tex]12 * \frac{3}{4}x - 12 *5 = \frac{5}{6} * 12[/tex]

Step-by-step explanation:
x=-6
Final Answer: [tex]x = -6[/tex]
Steps/Reasons/Explanation:
Question: What is [tex]\frac{1}{3} (x + 15) = 3[/tex]?
Step 1: Simplify [tex]\frac{1}{3}(x + 15)[/tex] to [tex]\frac{x+15}{3}[/tex].
[tex]\frac{x + 15}{3} = 3[/tex]
Step 2: Multiply both sides by [tex]3[/tex].
[tex]x + 15 = 3[/tex] × [tex]3[/tex]
Step 3: Simplify [tex]3[/tex] × [tex]3[/tex] to [tex]9[/tex].
[tex]x + 15 = 9[/tex]
Step 4: Subtract [tex]15[/tex] from both sides.
[tex]x = 9 - 15[/tex]
Step 5: Simplify [tex]9 - 15[/tex] to [tex]-6[/tex].
[tex]x = -6[/tex]

Use the figure below to determine what is RU
Answer:
20
Step-by-step explanation:

2x =5 (divide by 2 both sides)
x=2.5
8x= 8*2.5 = 20 (substitute 2.5 for x)
or 6x+5 = 6(2.5)+5 = 20 (substitute 2.5 for x)
