Helppppp plsss!!!!!!!!!!!

Answer:

6 hours

Step-by-step explanation:

speed = distance/ time

6000meters to km = 6000/1000= 6km

speed for the first race = 6/2

speed = 3km/hr

for the second race

speed = distance/time

3 = 18/time

cross multiply

3* t = 18

divide both sides by 3

t = 18/3

t = 6 hours

Answer:

Ronald will take 6 hours to complete the 18 km race if he maintains this speed.

Step-by-step explanation:

6000m in 2h = 6km in 2h

multiply by 3:

18km in 6h

Have a nice day!

Given:

The package weighed 350,000 centigrams.

To find:

The conversions that are equivalent to 350,000 centigrams

Solution:

We know that,

1 centigrams (cg) = 0.000001 kilograms (kg)

1 cg = 0.1 decigrams (dg)

1 cg = 0.001 dekagrams (dag)

1 cg = 0.01 grams (g)

Using these conversions, we get

350,000 centigrams = 3.5 kilograms

350,000 centigrams = 35,000 decigrams

350,000 centigrams = 350 dekagrams

350,000 centigrams = 3,500 grams

Therefore the correct options are C and D.

Step-by-step explanation:

Using the function concept, it is found that the meaning of the point is that the weight of the elephant during the first month is of 80 pounds.

In a function, represented by a set of ordered points (x,y), one value of the input x can be related to only one value of the output y.

In this problem, x is the age in months, while y is the weight in pounds, hence the meaning of point (1,80) is that the weight of the elephant during the first month is of 80 pounds.

Margin of error is 4.645% with 95% confidence that the mean number of hours all the residents of the city are watching news on television is 1.8 .

Data given :

A researcher surveyed 220 residents of a city about the number of hours they spend watching news on television each day. The mean of the sample was 1.8 with a standard deviation of 0.35 .

The researcher can be 95% confident that the mean number of hours all the residents of the city are watching news on television is 1.8 with what margin of error,

By formula of margin of error = [tex]M = 1.96 \times S / \sqrt{N} ,[/tex]

[tex]Margin \ of \ error, \ M = z \times \frac{s}{\sqrt{N}}[/tex]

z - represents the z-value for the required confidence level .

s - represents the standard deviation of the sample .

N - represents the sample size .

Now, using the above information, compute the margin of error as -

[tex]\therefore \ Margin \ of \ error, \ M = z \times \frac{s}{\sqrt{N}} \\= 1.96 \times \frac{0.35}{\sqrt{220}}[/tex]

[tex]=0.04625 (rounded \ to \ 5\ decimal\ places) \\\\ =4.625\%[/tex]

Thus, the margin of error, M, is approximately 4.625% .

Answer:

Final price = $2034

Step-by-step explanation:

Given the following data;

Marked price = $2000

Tax = 13%

Discount = 10%

To find the final sales price;

First of all, we would calculate the discount price

Discount price = 10/100 * 2000

Discount price = 20 * 10 = $200

New Price = marked price - discount price

New Price = 2000 - 200 = 1800

Next, we calculate the tax on the product;

Tax = 13/100 * 1800

Tax = 0.13 * 1800

Tax = $234

Finally, we would determine the final price;

Final price = marked price + Tax

Final price = 1800 + 234

Final price = $2034

If the 'm' u r trying to say is slope of line on the graph then it will be parallel to x axis

Answer:

a) 0.1859 = 18.59% probability that 5 will survive.

b) 0.1181 = 11.81% probability that 8 will survive.

c) 0.0016 = 0.16% probability that 12 will survive.

Step-by-step explanation:

For each patient, there are only two possible outcomes. Either they survive, or they do not. The probability of a patient surviving is independent of any other patient. This means that the binomial probability distribution is used to solve this question.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

In which [tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

And p is the probability of X happening.

The probability that the patient recovers from a rare deadly disease is 40%

This means that [tex]p = 0.4[/tex]

15 individuals

This means that [tex]n = 15[/tex]

a. 5 will survive

This is P(X = 5). So

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

[tex]P(X = 5) = C_{15,5}.(0.4)^{5}.(0.6)^{10} = 0.1859[/tex]

0.1859 = 18.59% probability that 5 will survive.

b. 8 will survive

This is P(X = 8). So

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

[tex]P(X = 8) = C_{15,8}.(0.4)^{8}.(0.6)^{7} = 0.1181[/tex]

0.1181 = 11.81% probability that 8 will survive.

c.12 will survive

This is P(X = 12). So

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

[tex]P(X = 12) = C_{15,12}.(0.4)^{12}.(0.6)^{3} = 0.0016[/tex]

0.0016 = 0.16% probability that 12 will survive.

Answer:

Step-by-step explanation:

The marked angles are supplementary, so ...

  (5x +26)° +(8x -2)° = 180°

  13x = 156 . . . . . . . . . . . . . . divide by °, subtract 24

  x = 12 . . . . . . . . . . . divide by 13

  ∠H = (8x -2)° = (8·12 -2)°

  ∠H = 94°

1) true

2)false

Step-by-step explanation:

1) 5(3)+2(4) = 23

= 15+8=23

23=23

thus, (3,4) is solution for 5x + 2y = 23

2) 5(0)+2(4) =23

= 0+8 is not 23

thus, (0,4) is not solution for 5x + 2y = 23

Answer:

Nope

Step-by-step explanation:

No because you can (12 + 6) +2 and get 8. so yea

Each cheeseburger was $5.25.

Step-by-step explanation:

He purchased:

A taco for $2.75.

Four cheeseburgers, each for x.

In total, he spent $23.75.

How much was each cheeseburger​?

This is the value of x. We have that:

[tex]2.75 + 4x = 23.75[/tex]

[tex]4x = 21[/tex]

[tex]x = \frac{21}{4}[/tex]

[tex]x = 5.25[/tex]

Each cheeseburger was $5.25.
