Kieran picks a bead out of a bag without looking.He records the colour and replaces the bead.Kieran does this 50 times.He picks out a red bead 15 times. Estimate the probability of picking a red bead.

Answers

Answer 1

Answer: 3/10

Step-by-step explanation:

From the question, we are informed that Kieran picks a bead out of a bag without looking and that he records the colour and replaces the bead.

He does this 50 times and he picks out a red bead 15 times. The probability of picking a red bead will be the number of times a red bead was picked divided by the number of title times a bead was picked. This will be:

= 15/50

= 3/10

Mr. Lyle made a round trip between two cities that were 450 kilometers apart. On the return trip, he increased his average of rate travel by 5 km/h and made the trip in one hour less. Find his rate for each direction.

Answers

Answer:

45 km/h

50 km/h

Step-by-step explanation:

Distance traveled in one way = 450 km

Let x = Velocity when he was going to his destination in km/h

He traveled 5 km/h faster when he returned so his velocity was [tex]x+5[/tex]

It took him 1 hour less when he returned so

[tex]\dfrac{450}{x}-\dfrac{450}{x+5}=1\\\Rightarrow x^2+5x-2250=0\\\Rightarrow x=\frac{-5\pm \sqrt{5^2-4\times 1\times \left(-2250\right)}}{2\times 1}\\\Rightarrow x=45,-50[/tex]

So, velocity while going to his destination is 45 km/h

While returning his velocity was 45+5 = 50 km/h.

To find:

The value of the expression when [tex]p=\dfrac{1}{2}[/tex] and [tex]q=7[/tex].

Solution:

We have,

[tex]8p+3q-18[/tex]

Putting [tex]p=\dfrac{1}{2}[/tex] and [tex]q=7[/tex], we get

[tex]8(\dfrac{1}{2})+3(7)-18[/tex]

[tex]=4+21-18[/tex]

what is the answer to -4(2d+3)+2(-d+4)?

Answers

Answer:

-10d-4

Step-by-step explanation:

Well, you're in luck because I LOVE distributive property!!!

-4(2d+3) Multiply -4 by 2d to get -8d, and multiply -4 by 3 for -12, so the result would be -8d-12!

Then, 2(-d+4) and therefore 2 times -d (you can just say -1d) to get -2d and 2*4 would be 8 to make -2d+8!

Now you combine them: -8d-12+-2d+8

Combine like terms!

-10d-4 would be your answer.

Step-by-step explanation:

6^2+8^2=c^2 (c is the hypotenous)

100=c^2

c=10

a^2+b^2=c^2
[^2= squared]

Plug in your numbers.

6^2+8^2=c^2

36+64=c^2

100=c^2

10=c

Answers

I'm assuming you mean that <C=68 degrees.

Now we know that the interior angle of a triangle adds up to 180 degrees.

We just need to subtract the 2 already known angles from it.

180 degrees-56 degrees-68 degrees=180 degrees-124 degrees=56 degrees.

Done!

<B=56 degrees.

Any questions you can ask in the comments, also something to look out for always capitalize your letter when you are writing angles :)!
