Answer:
18/21
Step-by-step explanation:
7x3 = 21
6x3=18
Answer:
18
Step-by-step explanation:
[tex]\frac{6}{7} =\frac{x}{21} \\\\\frac{6}{7} =\frac{18}{21}[/tex]
Multiply 3 to 6 since 7 x 3 is 21,
so 6 x 3 = 18

Answer:
y = -3x +4
Step-by-step explanation:
The hint tells you the slope stays the same. Every point moves to 2 times its original distance from the origin. So, the new y-intercept will be (+2)(2) = +4. The dilated line is ...
y = -3x +4

A cell culture currently contains 4 thousand cells, and is growing at a rate of r (t) = 8e^0.18t thousand cells per hour, where t is the number of hours since now. Find the total cell count after 3 hours. Give your answer accurate to at least 2 decimal places.
Answer:
20.00 thousand cell
Step-by-step explanation:
The problem can be solved using integration
[tex]\begin{aligned} r &=4+\int_{0}^{3} 8 e^{0.18 t} d t \\ &=4+3 \cdot\left[\frac{e^{0.18t}}{0.18}\right]_{0}^{3} \\ &=4+\frac{3}{0.18}\left(e^{0.18(3)}-e^{0.18(0)}\right) \\ &=19.9996 \end{aligned}[/tex]
[tex]\approx 20.00[/tex] thousand cells
the correct answer upto 2 decimal place.
what is the value of m when m/2=4.8
Answer: 9.6
Step-by-step explanation:
You need to isolate the m and in order to do that then you have to multiply both sides by 2
So m/2 x 2 = m
4.8 x 2 = 9.6 which is the answer
Answer:
m = 9.6Step-by-step explanation:
m/2 = 4.8
m = 4.8×2
m = 9.6
The rectangular box can be constructed from the pattern above. The box has a length of 8 units, a width of 2 units, and a height of 2 units. What is the surface area of the box?
Answer:
72 units
Step-by-step explanation:
SA=2lw+2lh+2hw
SA=2(8x2) + 2(8x2) + 2(2x2) Note, Not distributive
SA= 2(16) + 2(16) + 2(4)
SA= 32 + 32 + 8
SA= 72
Answer:
72 sq. units
Step-by-step explanation:
There are four rectangles of length 8 units and width 2 units, and two squares of length 2 units each.
area of one rectangle=8×2=16 sq. units
area of four rectangles=16×4=64 sq. units
area of on square=2×2=4 sq. units
area of two squares=4×2=8 sq. units
total surface area=64+8=72 sq. units

How many cubes of edge 4cm, each can be cut out from cuboid whose length, breadth and height are 20 cm, 18 cm and 16 cm respectively.
Answer:
90 cubes.
Step-by-step explanation:
First we find volume of the cuboid.
Volume = l x b x h = 20 x 18 x 16 = 5760 cm³
Now,
Volume of a single cube = l³ = 4³ = 64
No of cubes that can be cut out from the cuboid is
= Volume of cuboid/ volume of cube
= 5760/ 64
= 90 cubes

Fischer and Spassky play a chess match in which the first player to win a game wins the match. After 10 successive draws, the match is declared drawn. Each game is won by Fischer with probability 0.4, is won by Spassky with probability 0.3, and is a draw with the probability 0.3 independent of previous games.
(a) What is the probability that Fischer wins the match?
(b) What is the PMF of the duration of the match?
Answer:
a)
the probability that Fischer wins the match is 0.5714
b)
p( D = d ) = { [tex]( 0.3 )^{d-1[/tex] [tex](0.7)[/tex], d = 1, 2, 3, ........
[tex]0[/tex] otherwise
Step-by-step explanation:
Given that;
probability that Fischer wins the match, p = 4
probability that Spassky wins the match, q = 0.3
Match drawn, 1 - p - q = 1 - 0.4 - 0.3 = 0.7
(a) What is the probability that Fischer wins the match?
P( Fischer wins) = p/( p+q)
we substitute
P( Fischer wins) = 0.4 / ( 0.4 + 0.3)
P( Fischer wins) = 0.4 / 0.7
P( Fischer wins) = 0.5714
Therefore, the probability that Fischer wins the match is 0.5714
b) What is the PMF of the duration of the match?
let D represent the duration of the match
since the duration D of the match is a geometric random variable with parameter p + q,
the PMF will be;
p( D = d ) = [tex]( 1 - p - q )^{d-1[/tex] ( p + q )
= [tex]( 1 - 0.4 - 0.3 )^{d-1[/tex] ( 0.4 + 0.3 )
p( D = d ) = [tex]( 0.3 )^{d-1[/tex] ( 0.7)
that is, p( D = d ) = { [tex]( 0.3 )^{d-1[/tex] [tex](0.7)[/tex], d = 1, 2, 3, ........
[tex]0[/tex] otherwise
Mrs. Bhatia's closet consists of two sections, each shaped like a rectangular prism. She plans to buy mothballs to keep the moths away. She needs one box for every 32 cubic feet of space. How many boxes should she buy?
Answer:
6.5 boxes
Step-by-step explanation:
Given
See attachment for closet
Required
Determine the number of boxes needed to fill the closet
First, we calculate the volume of the two section.
According to the attachment
The first section has the following dimension:
[tex]Width = 5ft[/tex]
[tex]Length = 4ft[/tex]
[tex]Height = 8ft[/tex]
The second has the following dimension:
[tex]Width = 3ft[/tex] ---- see the last label at the top
[tex]Length = 2ft[/tex] --- This is calculated by subtracting the length of the first section (4ft) from the total length of the closet (6ft) i.e. 6ft - 4ft
[tex]Height = 8ft[/tex]
So: The volume of the closet is:
[tex]Volume = W_1 * L_1 * H_1 + W_2 * L_2 * H_2[/tex]
[tex]Volume = 5ft * 4ft * 8ft + 3ft * 2ft * 8ft[/tex]
[tex]Volume = 160ft^3 + 48ft^3[/tex]
[tex]Volume = 208ft^3[/tex]
The number of box needed is then calculated by dividing the volume of the closet (208ft^3) by the volume of each box (32ft^3)
[tex]Boxes = \frac{208ft^3}{32ft^3}[/tex]
[tex]Boxes= \frac{208}{32}[/tex]
[tex]Boxes = 6.5[/tex]
