Mathematics

Leokris [45]4 years ago
5 0

Answer:

False

Step-by-step explanation:

The angles are the same, but we know nothing about the sides

For triangles to be congruent, the sides have to be the same length

Since we don't have information about the sides, we do not know if they are congruent.

Alinara [238K]

Answer:

d. Yes. All conditions for inference have been met.

Step-by-step explanation:

A study was conducted to investigate the effectiveness of a new drug whether it could significantly reduce pan in people with arthritis.

From a group of 500 people with arthritis 250 were randomly assigned to receive the drug (group 1) and the remaining people were assigned a placebo (group 2).

It is given that the people in the study were selected randomly.

The pooled proportion is given by

Pe = no. of people who reported pain relief in both groups/total number of people

Pe = (225 + 150)/500

Pe = 375/500

Pe = 0.75

Now let us check the condition np ≥ 10

250*0.75

187.5 ≥ 10

Satisfied

Now let us check the condition n(1 - p) ≥ 10

250(1 - 0.75)

250*0.25

62.5 > 10

Satisfied

Therefore, all conditions for inference have been met option d is the correct option.

The standard form of the number 5, 976,000,000,000,000,000,000,000 is​
nirvana33 [79]

Answer:

5.976\times10^{24}

Step-by-step explanation:

<em>Standard form</em>, also called <em>scientific notation</em>, is a more compact way of writing very big or very small numbers. All numbers in scientific notation have the form

m\times10^b

where m is a number between 1 and 10, and b is an integer that represents how we've shifted the decimal point from the original number. For example, the number 23,000 in standard form would be written as 2.3 × 10⁴, since we have to shift the decimal point 4 places to the right to get back our original number.

We can turn 5,976,000,000,000,000,000,000,000 into a number between 1 and 10 by shifting the decimal 24 places to the left, giving us 5.976. We'll save that 24 as the exponent for our 10, giving us the final form

5.976\times10^{24}
