Answer:

Step-by-step explanation:

for first fox

let it be x

x + 135 degree = 180 degree (being straight line)

x = 180 - 135

x = 45 degree

therefore figure upper box is 45 degree

for box that is just below 135 degree

first fox = box just just below 135 degree

45 degree = box just below 135 degree

for box that is just below 45 degree

box that is just below 45 degree = 135 degreee (being vertically opposite angles)

for the box that lies on the left side of the transversal

let the fourth box that les on the left side be x

135 + x = 180 degree (being co interior angle)

x = 180 - 135

x = 45 degree

for the box that lies on the right side of the transversal .Let it be y

45 + y = 180 degree

y = 180 - 45

x = 135 degree

y = last box that lies on the left side of 45 degreeing vetically opposite angles)y

last box = 135 degree

In the healthy handwashing survey conducted by Bradley Corporation, a study was found that 64% of adult Americans operate the fl

Hitman42 [59]

Answer:

A) It fulfills the condition of binomial experiment

B) P (x=12) =0.1678

C)P ( x ≥16)= 0.1011

d) P (x>17) =0.0096 < 0.5

Step-by-step explanation:

A. The binomial probability distribution has the following four properties

1. the outcomes of each trial maybe classified into success and failure.

2) the probability of success p remains constant for all trials.

3) the successive trials are all independent.

4) the experiment is repeated a fixed number of times ,n.

These all conditions are fulfilled by the given question so it is a binomial experiment.

B) P (x=12) = 20C12 (0.64)^12 * (1-0.64)^8= 0.1678

C) P ( x ≥16) = P (x=16) + P (x=17) + P (x=18) + P (x=19)+ P (x=20)

where

P (x=16)= 20C16 (0.64)^16 * (1-0.64)^4= 0.0645

P (x=17)= 20C17 (0.64)^17 * (1-0.64)^3= 0.0270

P (x=18)= 20C18 (0.64)^18 * (1-0.64)^2= 0.0080

P (x=19)=20C19 (0.64)^10 * (1-0.64)^1= 0.0015

P (x=20)= 20C20 (0.64)^20 * (1-0.64)^0= 0.0001

P ( x ≥16)= 0.0645+ 0.0270 +0.0080+ 0.0015+0.0001= 0.1011

d) P (x>17)= P (x=17) + P (x=18) + P (x=19)+ P (x=20)

=0.0270 +0.0080+ 0.0015+0.0001

=0.0096

From this we see that the probability of more than 17 people who flush public toilets with their foot is unusual because it is far away from the mean which is supposed to be somewhere 0.5 in a given distribution.

Find the greatest common factor: 12ab^2c^4 + 20a^4bc^3 + 16a^3b

nordsb [41]

Option A

The greatest common factor is 4ab

Solution:

Given that,

We have to find the greatest common factor

$12ab^2c^4+20a^4bc^3+16a^3b$

First find the GCF of numbers

GCF of 12, 20, 16

The factors of 12 are: 1, 2, 3, 4, 6, 12

The factors of 16 are: 1, 2, 4, 8, 16

The factors of 20 are: 1, 2, 4, 5, 10, 20

Then the greatest common factor is 4

Now find the GCF of variables

$ab^2c^4\\\\a^4bc^3\\\\a^3b$

Here,

ab is the greatest common factor

Therefore, GCF of variables is ab

Thus, GCF of given expression is: 4ab

If v varies directly as w and v = 8 when w=1/2 find the equation that relate v and w

garri49 [273]

Answer:

v=kw. 8=k1/2

Step-by-step explanation:

Okay, so here's the equation. v=kw. Varies directly means if v rises, then w rises. If v decreases, then w will decrease. Let me know if that helps! (In case you need it, k=16.)
