Mathematics
1 answer:
tresset_1 [31]2 years ago
8 0

Answer:

x= 8

Step-by-step explanation:
Angles ∠LPJ and ∠MPK are equal to each other

So ∠LPJ = (3x+12)

We can add angles ∠LPJ and angle ∠JPQ for a total of 90 degrees

Now with the below equation set up, you can solve for X.

(3x+12)+(9x-18)=90
12x -6 = 90
12x = 96
x=8

Scorpion4ik [409]

Answer:

a. 5 \frac{21}{40}

b. \frac{1}{42}

Step-by-step explanation:

a. \: 12 \frac{2}{5}  - 6 \frac{7}{8}

\frac{62}{5}  -  \frac{55}{8}

\frac{62}{8}  \times   \frac{8}{8}  -   \frac{55}{8}   \times  \frac{5}{5}

\frac{62 \times 8 - 55 \times 5}{40}

\frac{221}{40}

5 \frac{21}{40}

b. \:  \frac{3}{14}  -  \frac{4}{21}

\frac{3}{14}  \times  \frac{3}{3}  -  \frac{4}{21}  \times  \frac{2}{2}

\frac{3 \times 3}{42}  -  \frac{4 \times 2}{42}

\frac{1}{42}

Hope it is helpful....

The manager of a shopping mall distributed a customer-satisfaction survey by handing it to people as they came through one of th
Tresset [83]

Answer:

The correct option is D.  No, because a random sample from all customers of the shopping mall was not selected

Step-by-step explanation:

In statistics, Bias can be described as a term which depicts error if a sample is not taken evenly or it depicts errors taken from an unjust sampling.

In statistics, sampling bias means the errors which occur if one part of the population is favoured more then the rest of the populations. In this kind of bias, the individuals for experimentation are not chosen randomly.

As the customer satisfaction survey was distributed in only one of the gates hence, it does not give a generalized result and the result is biased.
