According to the data give, the mean is 120, with a standard deviation of 8. 60% or a z-score of 1 would be those with 128. Thank you for your question. Please don't hesitate to ask in Brainly your queries.
Answer:
True
Step-by-step explanation:
A convenience sample is a sample where you pick whoever is convenient so that would mean whoever is around so it is unrepresentative of the larger group.
Yes if u can multiply 10 by 1000 then it is a multiplication fact
Solution: We have to find the probability of randomly selecting four person committee consisting entirely of women from a pool of 12 men and 15 women.
The number of ways 4 women can be selected from 15 women is:
15C4
The number of ways 4 persons can be selected from total 12+15 = 27 persons is:
27C4
Therefore, the probability of randomly selecting four person committee consisting entirely of women from a pool of 12 men and 15 women is:
The event of selecting a woman and the event of selecting a woman the next time are dependent because the probability of selecting a woman at first draw is not same as the probability of selecting a woman at second draw.
The <u>congruency theorem</u> gives you an opportunity to prove that <u>two triangles</u> are <u>congruent</u>.
Consider triangles WUT and VTU. In these triangles:
- WU≅VT (given);
- ∠T≅∠U, m∠T=m∠U=90° (from the diagram);
- side TU is common.
Note that triangles WUT and VTU are right triangles, because m∠T=m∠U=90°. Side TU is common leg and sides WU and VT are hypotenuses.
HL theorem states: if the hypotenuse (WU) and one leg (TU) of a right triangle (ΔWUT) are congruent to the hypotenuse (VT) and one leg (TU) of another right triangle (ΔVTU), then the triangles are congruent.
