2 times each day

1 liter is 1000 milliliters

the watering can has a capacity of 3 liters which is 3000 milliliters

her plants need 6,000 milliliters of water each day which means that she will need to fill her watering can twice a day.

The number of hours he spent babysitting is 12 hours and the number of hours he spent mowing lawns last week is 8 hours.

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

Given that, John works two jobs. He earns $10 an hour babysitting his neighbour's children and $15 an hour mowing lawns in his neighbourhood. Last week he worked a total of 20 hours and earned a total of $240.

Let the x be the number of hours he spent babysitting and y be the number of hours he spent mowing lawns last week,

Establishing the equation, we get,

x+y = 20

x = 20-y......(i)

10x+15y = 240.......(ii)

Using the equation (i) in (ii), we get

10(20-y)+15y = 240

200-10y+15y = 240

5y = 40

y = 8

Put y = 8 in eq(i)

x = 20-8

x = 12

Hence, the number of hours he spent babysitting is 12 hours and the number of hours he spent mowing lawns last week is 8 hours.

Answer: The tailor made 8 complete hats

Step-by-step explanation:

Amount of fabrics available to make hat = 6 2/3 yards

1 hat requires = 5/6 yards

Number of hat to obtain from the available fabric = Amount of fabrics available to make hat / requirement of 1 hat

=(6 2/3) / (5/6)

(20/3) / (5/6)

20/3 x 6/5 = cancelling out, we are left with

4x2= 8 hats

or

(20/3) / (5/6)

6.6666 /0.83333

= 8.00002= 8 hats

Answer:

3. 12p = 48

Step-by-step explanation:

Start with 12p = 48

Your goal is to find the number of photos, p, that can go on each page. To do this, you need to isolate p (in other words, get p by itself)

Divide both sides by 12 and you end up with:

p = 4

Answer:

Step-by-step explanation:

The value of P(x>6) is 1/5.

Statistics is the discipline that concerns the collection, organization, analysis, interpretation, and presentation of data.

Given that A distribution is given as X ~ U(0, 12).

We need to find the value of  P(x > 6)

The probability density function of the uniform distribution is defined as:

f(x)=1/b-a, a<x<b

a=0 and b=12

f(x)=1/12 , 0<x<12

The required probability is P(x>6)

Now P(x>6)= [tex]\int\limits^2_6 {f(x)} \, dx[/tex]

P(x>6)=(12/12-6/12)

=1-1/2

=1/2=0.5

Hence, the value of P(x>6) is 1/5.

Step-by-step explanation:

The different possibilities for flipping two coins are:

TT

TH

HT

HH

Only 1/4 is two heads.

Since you're finding the best prediction possible for the number of times both coins will land on heads out of 4 times, that means its 1/4 * 4  = 1 time

Answer:

1/4 is the probablity

Step-by-step explanation:

if you flip 2 coins one time the no.of outcome are 4 if you flip is 4 time no.of outcomes are 16

P(E)= favourable outcomes/ total no.of outcomes

= 4/16

= 1/4

PLS MARK BRAINLIEST, THNX

Answer:

5.1%

Step-by-step explanation:

We are told that 30 shares of Stock are purchased for $15/share..

This gives a total value of: 30 × 15 = $450.

Now,they are sold for $480 with a commission of $6. This means the final money getting to the seller is; 480 - 6 = $474.

Thus; rate of return percentage = (474 - 450)/474) × 100% = 5.06%

To the nearest tenth gives; 5.1%

The rate of return is 5.1%.

Given that,

Based on the above information, the calculation is as follows:

The total value should be

[tex]= 30 \times 15[/tex]

= $450.

Since it is sold for $480 along with commission of $6 so final money should be  

= 480 - 6

= $474.

Now rate of return is

[tex]= ((474 - 450)\div 474) \times 100%[/tex]

= 5.06%

= 5.1%

Answer:

Point-Slope Form: y-2 = -1(x+7) Slope-Intercept Form: y = -x-5 Standard Form: x+y = -5

Step-by-step explanation:

Because we were giving the slope and a point, we can write this in point-slope form.

Point-Slope Form: y-y1=m(x-x1)

Substitute the point and slope into (x1,y1) and m: y-2 = -1(x-(-7))  

y-2 = -1(x-(-7))  = y-2 = -1(x+7)

y-2 = -1(x+7)

If want in slope-intercept form (y=mx+b),

y-2 = -1(x+7)

y-2 = -1x-7

y = -1x-5 = y = -x-5

To convert to standard form (ax+by=c)

y = -x-5

y+x = -5 = x+y = -5

Answer:

0.2990 = 29.90%.

Step-by-step explanation:

For each trial, there are only two possible outcomes. Either you win $400, or you do not. Trials are independent. So we use the binomial probability distribution 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.

Probability of winning $400 in a trial:

1/4 probability of choosing the suitcase containing $400, and in this case, 0.7 probability of keeping it.

3/4 probability of choosing another suitcase. Then, 0.3 of 3/4 probability of changing the suitcase, and 0.5 of 0.3 of 3/4 probability of getting the suitcase containing $400. So

[tex]p = \frac{1}{4}*0.7 + \frac{3}{4}*0.3*0.5 = 0.25*0.7 + 0.75*0.15 = 0.2875[/tex]

If you play this game five times, the probability that the event W400 occurs twice in five trials is:_______

This is P(X = 2) when n = 5. So

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

[tex]P(X = 2) = C_{5,2}.(0.2875)^{2}.(0.7125)^{3} = 0.2990[/tex]

The probability is 0.2990 = 29.90%.
