The probability that it will snow on Friday is 70%, and the probability that it will snow on Saturday is 50%.

What is the probability that it will snow on both days? Express your answer as a decimal rounded to the nearest hundredth.

What is the probability that it will not snow on either day? Express your answer as a decimal rounded to the nearest hundredth.

Answers

Answer 1

P(Snow Friday) = 0.7, P(No Snow Friday) = 1-0.7 = 0.3
P(Snow Saturday) = 0.3, P(No snow Saturday) = 1-0.3 = 0.7

Then,
P(Snow Friday) and P(Snow Saturday) = 0.7*0.3 = 0.21

P(No snow Friday) and P(No snow Saturday) = 0.3*0.7 = 0.21

Josiah has a piece of wood that measures 10 1 / 8 feet he wants to make 5 shelves if each shelf is 1 3/4 fuel long does he have enough to make 5 shelves explain

Answers

To answer, I'm assuming "fuel long" means "feet long"
To find the amount of feet to make 5 shelves, we must multiply the amount to make one shelf by 5
1.75 * 5 = 8.75
(1.75 is the decimal form for one shelf)
Because 8.75 is less than 10, he has enough to make 5 shelves

a dump truck weighs 11.25 tons. a conveyor belt pours sand into the truck at a constant rate of 1/4 ton per minute. the dump truck weighs 18 tons when filled. at the same time the dump truck is being filled, an identical truck filled to capacity is being emptied at a rate of 1/8 ton per minute. how much sand is in each dump truck when the trucks are the same weight?

Answers

We know these variables:

W1B = Weight of the truck 1 before starting the filling.
W1A = Weight of the truck 1 when filled.
R1F = Rate of change (Truck 1 being filled)

W2B = Weight of the truck 2 before starting the filling.
W2A = Weight of the truck 2 when filled.
R2F = Rate of change (Truck 2 being filled)

Given that a conveyor belt pours sand into the truck and stops when filled, then the amount of sand, when the truck is filled to capacity, is:

[tex]S = W_{1B} - W_{1A} = 18-11.25 = 6.75Tons[/tex]

Let's analyze Truck 1:

Given that the rate of change is:

[tex] \frac{1}{4} ton/min[/tex]

This means that in 1min the amount of sound poured is 1/4Ton, then the time elapsed when filled using rule of three is:

[tex]t = \frac{6.75}{ \frac{1}{4} } = 27min[/tex]

A similar analysis happens with Truck 2:

Given that the rate of change is:

[tex] \frac{1}{8} ton/min[/tex]

Then:

[tex]t = \frac{6.75}{ \frac{1}{8}} = 54min[/tex]

Now we can find two straight lines:

Truck 1:

[tex]\left \{ {{t=0min} \atop {S=0Ton}} \right. [/tex]

[tex] \left \{ {{t=27min} \atop {S=6,75Ton} \right[/tex]

[tex]S-S_{0} = m(t-t_{0})[/tex]

[tex]S-0 = \frac{6.75-0}{27-0} (t-0)[/tex]

∴ [tex]S = 0.25t[/tex]

Truck 2:

[tex] \left \{ {{t=0min} \atop {S=6.75Ton}} \right[/tex]

[tex] \left \{ {{t=54min} \atop {S=0Ton}} \right[/tex]

[tex]S-S_{0} = m(t-t_{0})[/tex]

[tex]S-6.75 = \frac{6.75-0}{0-54} (t-0)[/tex]

∴ [tex]S = -0.125t+6.75[/tex]

The trucks are the same weight when they have the same amount of sand, so solving for t:

[tex]0.25t = -0.125t+6.75[/tex]
[tex]0.375t = 6.75[/tex]
[tex]t = 18min[/tex]

Finally, the amount of sand in each truck:

[tex]S = 0.25(18) = 4.5Ton [/tex]

Final answer:

To find out how much sand is in each dump truck when they are the same weight, we can set up an equation based on the given information. Let's assume that the amount of sand in the first truck is x tons. We can then find the value of t that makes the weight of both trucks the same and substitute it into the equation to find x.

Explanation:

To find out how much sand is in each dump truck when they are the same weight, we can set up an equation based on the given information.

Let's assume that the amount of sand in the first truck is x tons. Since the conveyor belt pours sand into the truck at a constant rate of 1/4 ton per minute, the weight of the sand will increase by (1/4) * t tons, where t is the time in minutes.

Similarly, the second truck is being emptied at a rate of 1/8 ton per minute. So, the weight of sand in the second truck will decrease by (1/8) * t tons.

We know that the dump truck weighs 11.25 tons initially and 18 tons when filled. Therefore, we can set up the equation:

11.25 + (1/4) * t - (1/8) * t = 18 - x

Simplifying the equation:

(1/4) * t - (1/8) * t = 18 - 11.25 - x

(1/8) * t = 6.75 - x

t = 6.75 * 8 - 8x

Now, we need to find the value of t that makes the weight of both trucks the same. Let's substitute that value into the equation to find x.

5 ln ( x + 8 ) solve the equation for x

Answers

You have not given an equation.

If we make it an equation, then we can solve for x.
a = 5*ln(x +8)
a/5 = ln(x +8) . . . . . . . divide by 5
e^(a/5) = x +8 . . . . . . take the antilog

The compound interest formula is given by:

But:
P=$1000, r=3.25%, n=time

(1 point) Question 9 options: 1) 0.09 2) 0.29 3) 0.30 4) 0.37

Answers

Option D is correct (.37) Hope this helps!

Answer:

4) 0.37

Step-by-step explanation:

If the principal randomly selects a student in grade 10 from this survey, the probability that the student is opposed to extending the school day is a division of the number of students that opposed from 10 Grade by the total number of students of the 10 Grade.

The table of the question is as:

Grade In favor Opposed Undecided

9 6 4 8

10 10 11 9

11 12 15 11

12 15 6 14

So, there are 10 students in 10 grade that are in favor of the extended school day, 11 students that are Opposed and 9 students that are undecided about the extended school day. then, there are 30 student in 10 Grade

Then, the probability is:

The half-life of cobalt-60 is 5.20 yr. how many milligrams of a 2.000-mg sample remains after 6.55 years?

Answers

Answer:

0.835 mg of a 2.000-mg sample remains after 6.55 years.

Step-by-step explanation:

We are given that The half-life of cobalt-60 is 5.20 yr.

Formula of half life : [tex]N(t) = N(0)e^{\frac{-0.693t}{t\frac{1}{2}}}[/tex]

Where N(0) = Initial amount

N(t) = Quantity remaining after time

t = time

[tex]\frac{t}{2} =\text{half life}[/tex]

So, N(0) = Initial amount = 2 mg

t = time = 6.55 years

[tex]\frac{t}{2} =\text{half life} = 5.20 yr [/tex]

Substitute the values in the formula

Therefore,

[tex]N(t) = 2 e^{\frac{-0.693 \times 6.55}{5.20}}[/tex]

[tex]N(t) =0.835[/tex]

Hence 0.835 mg of a 2.000-mg sample remains after 6.55 years.
