Answer:
[tex]P(3) = 0.3397[/tex]
Step-by-step explanation:
The given details represent binomial distribution. So, we have:
[tex]n = 5[/tex]
[tex]p = 64\% = 0.64[/tex]
Required
Calculate P(3)
This is calculated using:
[tex]P(x) = ^nC_x * p^x * (1- p)^{n-x}[/tex]
This gives:
[tex]P(3) = ^5C_3 * 0.64^3 * (1- 0.64)^{5-3}[/tex]
[tex]P(3) = 10 * 0.64^3 * 0.36^2[/tex]
[tex]P(3) = 0.3397[/tex]

Answer:
A
Step-by-step explanation:
They have a rectangle ABCD as shown below, where AB = 24cm BC = 10cm and AE = 13cm
A. Calculate the volume of the rectangle ABCD
B. Calculate the circumference of the BCD triangle
C. Calculate the circumference of the BEC triangle
D. Calculate the circumference of the DEC triangle
Answer:
A. Area of ABCD = 240 [tex]cm^{2}[/tex]
B. 60 cm
C. 36 cm
D. 50 cm
Step-by-step explanation:
Given: AB = 24cm BC = 10cm and AE = 13cm.
A. Since a rectangle is a 2 dimensional figure, it has no volume but area.
So that,
the area of the rectangle ABCD = length x width
= 24 x 10
= 240 [tex]cm^{2}[/tex]
B. To calculate the circumference of the BCD triangle, apply the Pythagoras theorem to determine BD.
[tex]BD^{2}[/tex] = [tex]BC^{2}[/tex] + [tex]DC^{2}[/tex]
= [tex]10^{2}[/tex] + [tex]24^{2}[/tex]
= 676
BD = [tex]\sqrt{676}[/tex]
= 26
BD = 26 cm
so that,
the circumference of BCD = 10 + 24 + 26
= 60 cm
C. To calculate the circumference of the BEC triangle,
AC = 26 cm, AE = 13 cm
CE = 26 - 13
= 13 cm
CE = 13 cm
The circumference of the BEC triangle = 13 + 13 + 10
= 36 cm
D. The circumference of the DEC triangle = 13 + 13 + 24
= 50 cm

Perimeter of base =
Height =
Base area =
The surface area is
ft2
square feet.
Answer:
Step-by-step explanation:
Perimeter of the triangular base = 10 + 10 + 16
= 36 ft
Height of the prism = 15 ft
Base area = Area of the triangle
= [tex]\frac{1}{2}(\text{Base})(\text{Height}})[/tex]
= [tex]\frac{1}{2}(16)(6)[/tex]
= 48 square ft
Surface area of the triangular prism = 2(base area) + (perimeter × height)
= 2(48) + 36(15)
= 96 + 540
= 636 square ft

Answer:
x = √88.25 ≈ 9.4x = 15Step-by-step explanation:
1. x is the hypotenuse of a right triangle with legs 4.4 and 8.3. The Pythagorean theorem can be used.
x² = 4.4² +8.3² = 19.36 +68.89 = 88.25
x = √88.25 ≈ 9.394
x = 9.4 . . . . rounded to tenths

2. The product of segment lengths to the near and far circle intercept is the same for both secants.

(1.487³ - 1) ÷ (1.487³ + 1)
sove using log
Answer:0.533583
Step-by-step explanation:
The value of (1.487³ - 1) ÷ (1.487³ + 1) using log is 1.
What is a logarithm?The logarithm is the exponent or power to which a base must be raised to yield a given number.
If x is the logarithm of n to the base b then,
[tex]b^{x}[/tex] = n
Where,
x = [tex]log_{b}[/tex] n.
We have,
(1.487³ - 1) ÷ (1.487³ + 1)
We can solve this using log:
= log(1.487³ - 1)
= log 1.487³ - log1
= 3 log 1.487 - 0
[ log 1 = 0 and [tex]logm^{n}[/tex] = nlogm ]
= 3 x 0.1723
= 0.5169
Using log on (1.487³ + 1)
= log (1.487³ + 1)
= log 1.487³ + log 1
= 3 x log 1.487 + 0
= 3 x 0.1723 + 0
= 0.5169
Now,
(1.487³ - 1) ÷ (1.487³ + 1)
= 0.5169 ÷ 0.5169
= 1
Thus the value of (1.487³ - 1) ÷ (1.487³ + 1) using log is 1.

solve the following proportion 3/((x-2))=5/15
Answer:
x = 11
Step-by-step explanation:
Given
[tex]\frac{3}{x-2}[/tex] = [tex]\frac{5}{15}[/tex] ( cross- multiply )
5(x - 2) = 45 ( divide both sides by 5 )
x - 2 = 9 ( add 2 to both sides )
x = 11
if the area of a rectangle is x^2-9 and one dimension is x-3. what would be the other dimension?
Answer:
Step-by-step explanation:
x2-9 = 0
Area of one dimension = x-3= 0
So, x2= 9
Square root on both sides;
x= +3 and -3
x-3 is one side
x+3 is the other dimension

them in albums. Each album holds
480 postcards. His collection already
fills two albums and one-fourth of
another album. How many postcards
does Garth have?

480 + 480 + 1/4(480) = 1080
Answer:
1080 postcards
Step-by-step explanation:
WIth 2 full albums you take 480 and multiply it by 2 to get 960 and 1/4 of 480 is 120 because we divide 480 by 4 to get that and if we add 120 to 960 we get 1080.

Stephen rolls a fair dice 78 times. How many times would Stephen expect to roll a number greater than 2?
Answer:
52 times
Step-by-step explanation:
Given
[tex]n = 78[/tex] -- Number of times
Required
Determine the expected times to get > 2.
In a fair dice, the outcome > 2 are:
[tex]>2 = \{3,4,5,6\}[/tex]
The probability of the above is:
[tex]p = \frac{4}{6}[/tex]
[tex]p = \frac{2}{3}[/tex]
The number of times is calculated using:
[tex]E(x) = n * p[/tex]
[tex]E(x) = 78* \frac{2}{3}[/tex]
[tex]E(x) = \frac{78* 2}{3}[/tex]
[tex]E(x) = \frac{156}{3}[/tex]

(2,2) and (2,-2) slope?
Answer:
Undefined.
Step-by-step explanation:
Slope is equal to the change in y over the change is x, or rise over run.
[tex]m=\frac{change in y }{ change in x}[/tex]
The change in x is equal to the difference in x-coordinates, and the chnage in y is equal to the difference in y-coordinates.
[tex]m=\frac{y2-y1}{x2-x1}[/tex]
Substitute in the values of x and y into the equation to find the slope.
[tex]m= \frac{-2-(2)}{2-(2)}[/tex]
Simplify it. since -2-(2) and 2-(2) = nothing, the Slope is Undefined.
Hence, the slope is Undefined.
Answer:
Undefined
