Raj wakes up in the morning and notices that his digital clock reads 07 2(A)5(B).After noon, he looks at the clock again.what is

Gre4nikov [31]

Answer:

i. $P(A) = \frac{1}{10}$

ii. $P(B) = \frac{1}{10}$

iii. $P(A) = \frac{3}{5}$

iv. $P(B) = \frac{2}{5}$

Step-by-step explanation:

Given

Time: 07 2(A) 5(B)

Calculating (a)

First, we need to list out the possible sample space, S of A

$S = \{0,1,2,3,....,9\}$

$n(S) = 10$

Probability of A being a 4 is the number of occurrence of 4 divided by the number of sample space

$A = \{4\}$

$n(A) = 1$

Hence;

$P(A) = \frac{n(A)}{n(S)}$

$P(A) = \frac{1}{10}$

Calculating (b)

First, we need to list out the possible sample space, S of B

$S = \{0,1,2,3,....,9\}$

$n(S) = 10$

Probability of B being a 8 is the number of occurrence of 8 divided by the number of sample space

$B = \{8\}$

$n(B) = 1$

Hence;

$P(B) = \frac{n(B)}{n(S)}$

$P(B) = \frac{1}{10}$

Calculating (c)

Using the sample space in (a)

$n(S) = 10$

Probability of A being less than 6 is the number of occurrence of less than 6 divided by the number of sample space

$A = \{0,1,2,3,4,5\}$

$n(A) = 6$

Hence;

$P(A) = \frac{n(A)}{n(S)}$

$P(A) = \frac{6}{10}$

$P(A) = \frac{3}{5}$

Calculating (d)

Using the sample space in (b)

$n(S) = 10$

Probability of B being greater than 5 is the number of occurrence of greater than 5 divided by the number of sample space

$B = \{6,7,8,9\}$

$n(B) = 4$

Hence;

$P(B) = \frac{n(B)}{n(S)}$

$P(B) = \frac{4}{10}$

$P(B) = \frac{2}{5}$

Kyla makes a triangular school pennant. The area of the triangle is 180 square inches. The base of the pennant is z inches long.

kykrilka [37]

We can represent the base as z and the height as 2z+6. We are going to use the formula A=1/2*b*h and solve for z
180=1/2*z*(2z+6)
360=2z^2+6z
0=2z^2+6z-360
0=2(z^2+3z-180)
0=(z+15)(z-12)
So z=-15 and 12 but it must be positive so then the base is equal to 12

When we plug this into 2z+6 we get 30 for the height
2(12)+6=30

Hope this helps

Find all possible values of x in the similar triangles pqr stu

antoniya [11.8K]

If triangles PQR and STU are similar then PQ corresponds to ST and PR corresponds to SU. Therefore, PQ/ST=PR/SU
Considering that, PQ= 7-x, ST= 13-x, PR= x²+5 and SU= x² +20
therefore, (7-x)/(13-x)= (x²+5)/(x²+20)
cross multiplying,
7x² +140-x³+20x =13x²+65-x³-5x
combining the like terms,
6x² +15x -75=0
solving for x,
x = 5/2 or -5

Let f(x)= 7-2x Find a. f(4) b. f(h) c. f(4) + f(h) d. f(3+h)

anyanavicka [17]

Step-by-step explanation:

a) f(4) = 7-2(4)

= -1

b) f(h) = 7-2(h)

= 7-2h

c) f(4) + f(h) = -1 +(7-2h)

= 6-2h

h = 3

d) f(3+h) = 7-2(3+h)

= 7-6-2h

= -1-2h

2h= -1

h = -1/2

p/s = if the real answer is different with my answer, tell me also please. Im just a student that still learning.
