Step-by-step explanation:
Given that in a sample of 800 U.S. adults, 199 think that most celebrities are good role models. Two Two U.S. adults are selected at random from the population of all U.S. adults without replacement.
In 800 adults 199 are favourable and remaining 601 are against.
a) The probability that both adults think most celebrities are good role models is ________= Prob of selecting both from 199
=
=0.062
b) The probability that neither adult thinks most celebrities are good role models is _______=P(both selecting from 601)
=
=0.564
c) The probability that at least one of the two adults thinks most celebrities are good role models ______
=1-Prob that neither thinks
= 1- 0.564
= 0.436
Answer: blue= 93.625
Step-by-step explanation:
Let the red ball be y
Four times of red is 4y
And blue is seven times of red which means 7(4y)
4y+7(4y)=107
Open the bracket
4y+28y=107
32y=107
y=107/32
Make y the subject of formula
y=3.34
Therefore,blue is
7(4(3.34))
Blue= 93.625

Answer:
10 units
Step-by-step explanation:
Because the center of the circle is at (9 , 9) and passes through (4 , 9), <u>the radius must be 5.</u>
<em>Radius</em> - The length from the center of a circle to its edge
<em>Diameter</em> - The length from one edge of a circle to the opposite edge
The diameter is double the length of the radius, meaning D = 2(5).
2 × 5 = 10
So, the diameter of the circle is 10 units.
