there are 18 cups on the shelves in Mrs. Lee's kitchen. If she takes out 8 cups to serve tea, how many cups will be left?
Answers
Subtract the number of cups she takes from the total cups:
18 cups - 8 cups = 10 cups will be left
Given: c=58, b=15, angle B=15 degrees a= ?
a. 60
b. 52
c. 56
Answers
Answer:
c. 56
Step-by-step explanation:
To Find a= it would be opposite of angle A.
We could use trig ratios for this question.
Cos B= a/c
Cos 15= a/58
a = (cos15)(58)
a=56
A car travel 8km using 1 litres of petrol. How much petrol is needed to travel 152km
Answers
Answer:
It is very interesting!
Step-by-step explanation:
So I am going to take all of this values and represent it as a proportion, So here's how it is going to look,
Km : Litre : : Km : Litre
Let's keep the missing value as x
= 8 : 1 : : 152 : x
We know that,
Product of ext. terms = Product of middle terms
8 * x = 1 * 152
8x = 152
x = 152/8
x = 19
So therfore it will take 19 lites to travel 152 km.
(So to put everything in a nutshell we have to divide 8 by 152 to get the answer)
Hope this helps :)

Answers
Answer:
[tex]P(X=8) = 0.0194[/tex]
[tex]P(X \ge 8)= 0.9820[/tex]
[tex]P(X \ge 1)= 1[/tex]
[tex]P(X\le 1) = 0.0000049[/tex]
Step-by-step explanation:
Given
[tex]\lambda = 15[/tex]
Poisson distribution is given by:
[tex]P(X=x) = \frac{\lambda^x e^{-\lambda}}{x!}[/tex]
Solving (a): 8 bugs
This implies that:
[tex]x = 8[/tex]
So, we have:
[tex]P(X=8) = \frac{15^8 * e^{-15}}{8!}[/tex]
[tex]P(X=8) = \frac{783.99418938}{40320}[/tex]
[tex]P(X=8) = 0.0194[/tex]
Solving (b): At least 8 bugs
This is represented as: [tex]P(X \ge 8)[/tex]
Using complement rule:
[tex]P(X \ge 8)= 1 - P(X<8)[/tex]
Where
[tex]P(X<8) = P(X=1) + P(X=2) + P(X=3) + P(X=4) + P(X=5) + P(X=6) + P(X=7)[/tex]
[tex]P(X<8) = \frac{15^1 * e^{-15}}{1!} + \frac{15^2 * e^{-15}}{2!} + \frac{15^3 * e^{-15}}{3!} + \frac{15^4 * e^{-15}}{4!} + \frac{15^5 * e^{-15}}{5!} + \frac{15^6 * e^{-15}}{6!} + \frac{15^7 * e^{-15}}{7!}[/tex]
[tex]P(X<8) = (\frac{15^1}{1!} + \frac{15^2}{2!} + \frac{15^3 }{3!} + \frac{15^4}{4!} + \frac{15^5}{5!} + \frac{15^6}{6!} + \frac{15^7}{7!}) e^{-15}[/tex]
[tex]P(X<8) = (15 + 112.5 + 562.5 + 2109.375 + 6328.125 + 15820.3125 + 33900.6696429) *e^{-15}[/tex]
[tex]P(X<8) = 58848.4821429 *e^{-15}[/tex]
[tex]P(X<8) = 0.0180[/tex]
So:
[tex]P(X \ge 8)= 1 - P(X<8)[/tex]
[tex]P(X \ge 8)= 1 - 0.0180[/tex]
[tex]P(X \ge 8)= 0.9820[/tex]
Solving (c): At least 1
This is represented as: [tex]P(X \ge 1)[/tex]
Using complement rule:
[tex]P(X \ge 1)= 1 - P(X<1)[/tex]
[tex]P(X<1) = P(X = 0)[/tex]
[tex]P(X<1) = \frac{15^0 e^{-15}}{0!}[/tex]
[tex]P(X<1) = \frac{e^{-15}}{1}[/tex]
[tex]P(X<1) = e^{-15}[/tex]
So:
[tex]P(X \ge 1)= 1 - P(X<1)[/tex]
[tex]P(X \ge 1)= 1 - e^{-15[/tex]
[tex]P(X \ge 1)= 0.99999969409[/tex]
[tex]P(X \ge 1)= 1[/tex]
Solving (d): Not more than 1
This implies at most 1.
It is represented as:
[tex]P(X\le 1)[/tex]
It is calculated using:
[tex]P(X\le 1) = P(X = 0) + P(X =1)[/tex]
[tex]P(X = 0) = e^{-15}[/tex]
[tex]P(X=1) = \frac{15^1 * e^{-15}}{1!}[/tex]
[tex]P(X=1) = 15 * e^{-15}[/tex]
So:
[tex]P(X\le 1) = e^{-15} + 15 * e^{-15}[/tex]
[tex]P(X\le 1) = 0.00000489443[/tex]
[tex]P(X\le 1) = 0.0000049[/tex]

Solve the following values for x and y 1) (8x + 7) 5y (7y - 34) (9x - 4)
Answers
9514 1404 393
Answer:
x = 11y = 17Step-by-step explanation:
Vertical angles have the same measure, so we can equate expressions for each vertical angle pair:
top and bottom
8x +7 = 9x -4
11 = x . . . . . . . . . . add 4-8x to both sides
left and right
7y -34 = 5y
2y = 34 . . . . . . . . add 34-5y to both sides
y = 17 . . . . . . . divide by 2
_____
Additional comment
As a check on the integrity of the problem, we can see if these angles form linear pairs.
8x+7 = 8·11+7 = 95
5y = 5·17 = 85
95 +85 = 180 . . . . . . angle values have the expected relationship

Answer:
33°
Step-by-step explanation:
The law of cosines tells you ...
a² = b² +c² -2bc·cos(A)
Solving for A, we get ...
A = arccos((b² +c² -a²)/(2bc))
A = arccos((15² +24² -14²)/(2·15·24)) = arccos(605/720)
A ≈ 32.8305°
The smallest angle is about 33°.

[Linear System with Two Variables]
Given that:
y = 7x - 53y = -4x + 35(i) Find the value of x
Substitute the value of y in -4x + 35 with 7x - 53
Therefore we get
7x - 53 = -4x + 35-4x to the left side of "=" = + 4x
-53 to the right side of "=" = + 53
we get:
7x + 4x = 53 + 35
11x = 88
x = 8 ✅(ii) Find the value of y
y = 7x - 53

The answer to number 6: 230.4(the unit measurement "cm" "mm" etc)
The answer to number 7: 140.673538 rad
Step-by-step explanation:
For number 6: To find area, it is length times width times height. In this case, the length is 7.2. The width is 8. The height is 4.
So length (7.2) times width (8) times height (4).
7.2 times 8 is 57.6
57.6 times 4 is 230.4
For number 7: To find the area it is length times width times height. In this case, the length is 62°. The width is 13. The height is 10.
So length (62°) times width (13) times height (10).
62° times 13 is 14.0673538 rad
14.0673538 rad times 10 is 140.673538 rad
