Answer: [tex]\dfrac{5}{14}[/tex]

Step-by-step explanation:

Given: An urn contains 3 red and 5 orange marbles.

Total marbles = 3+5=8

Probability of getting orange marble = [tex]\dfrac{\text{Number of orange marble}}{\text{Total}}[/tex]

[tex]=\dfrac{5}{8}[/tex]

Now marbles left = 7

Orange marbles left = 4

and Probability of getting orange marble = [tex]\dfrac47[/tex]

The probability that the second marble selected is orange given that the first marble selected is orange[tex]=\dfrac58\times\dfrac47=\dfrac{5}{2}\times\dfrac17=\dfrac{5}{14}[/tex]

Required probability= [tex]\dfrac{5}{14}[/tex]

Answer: $2203.74

Step-by-step explanation:

Answer:

2.08secs

Step-by-step explanation:

Given the equation modeled by the height as h=-121t^2 +504t

The velocity of the object at the max height is zero, hence;

v = dh/dt = 0

dh/dt = -2(121)t + 504

dh/dt = -242t + 504

0 = -242t + 504

242t = 504

t = 504/242

t = 2.08secs

Hence the projectile reaches its maximum height after 2.08secs

Answer: -260

Step-by-step explanation:

Answer:

-260

Step-by-step explanation:

First, we have to distribute -10 to 32 and -6, since 32 - 6 is in parentheses.

So, the expression becomes -320 + 60, because -10 × 32 = -320 and -10 × -6 = 60.

So, -320 + 60 = -260

1/2 degree x 6 hours = 3 degree increase.

-12 + 3 = -9

The temperature at noon was -9 degrees.

Answer:

She needs to buy 420 candy hearts.

Step-by-step explanation:

15*28 = 420

15 per student, and there is 28 students

The number of candy hearts that she needs to purchase will be 420.

Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.

The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.

Miss Hillard is buying treats hearts to disperse to 28 understudies in her number-related class and Valentine's Day issue would like every understudy to get at least 15 sweets hearts.

Then the number of candy hearts that she needs to purchase will be given as,

⇒ 15 x 28

⇒ 420

The number of candy hearts that she needs to purchase will be 420.

Answer:

C

Step-by-step explanation:

Let's say you wanted to buy a television. The television cost $200 but you only have $100, so you ask your friend for some money. Your friend says they will give you money but you have to pay them back and pay them interest. So when you go pay them, you pay them $100 dollars along with the amount of money your friend wants you to pay them for borrowing their money. In the end you could end up giving them 120 instead of 100.

Answer:

172000

Step-by-step explanation:

Population growth from  2010 to 2015 if population increased by 8% =

1.08 x 168,000. = 181440

Population growth from  2015 to 2020 if population decreased by 5% =

0.95 x 181440 = 172,368

Rounding off to the nearest 100 people = 172,000

The population in the year 2020 is 172,368.

Since

In 2010, the population of a city was 168,000. From 2010 to 2015, the population grew by 8%. From 2015 to 2020, it fell by 5%.

So,

[tex]= 168000 \times 1.08 \times 0.95[/tex]

= 172,368

hence, The population in the year 2020 is 172,368.

Answer:

f(50) = 109.44943 feet

Step-by-step explanation:

Modeling

The model of a situation where the skid distance f is measured against the car speed x can be expressed as:

[tex]f(x) = 0.0425x^2 + 0.07381x - 0.49107[/tex]

Using this equation, we can predict the skid distance for a car that is driving at x=50 mph by substituting in the equation of the model:

[tex]f(50) = 0.0425*50^2 + 0.07381*50 - 0.49107[/tex]

[tex]f(50) = 106.25 + 3.6905 - 0.49107[/tex]

f(50) = 109.44943 feet
