juin [17]

In the deck of cards, there is a total of 52 cards which comprises of: kings, queens, jacks, 10, 9, 8, 7, 6, 5, 4, 3, 2, and aces.

In the problem, we were asked the probability of less than 5, so it would be Ace, 2, 3, and 4. 5 is not included since the problem didn’t ask less than or equal to.

So 4 cards and we have 4 suits in the deck. So 4 x 4 = 16.

16/ 52 = .31 is the probability.

What is the solution? 21=42−3r r=−8 r=−7 r = 7 r = 8

faltersainse [42]

R=-7, you have to put each answer in the equation, therefore; 21=42-3(-7) So you have to do multiplication (PEMDAS, if you arent aware of that acronym then it stands for the order of what to do with an equation, Parentheses get solved first, then Exponents, then multiplication, then division, then addition, then finally subtraction. Solving in that order will solve your answer correctly.) With -3 times -7 which gives you 21. Then you do 42 - 21 which equals 21. So 21 = 21.

In a survey of 90 students 20 choose rock.40 chose hip hop 30 chose country. In a school of 360 students how many would be expec

lina2011 [118]

Answer:

The students would be expected to choose rock be 80 or students choose hip hop be 160 or choose to country be 120.

Step-by-step explanation:

Given:

In a survey of 90 students 20 choose rock, 40 choose hip hop and 30 choose country.

Now, to find the students expected to choose hip hop or rock or country in a school of 360 students.

Let the number of students expected to choose rock be $x.$

Let the number of students expected to choose hip hop be $y.$

Let the number of students expected to choose country be $z.$

Total number of students = 360.

Now, to get the number of students choosing hip hop or rock or country by using cross multiplication method:

In a survey of 90 students 20 choose rock.

So, 90 is equivalent to 20.

Thus, 360 is equivalent to $x$ .

$\frac{90}{20} =\frac{360}{x} \\\\By\ cross\ multiplying\ we\ get:\\\\90x=7200\\\\Dividing\ both\ sides\ by\ 90\ we\ get:\\\\x=80.$

Thus, the number of students expected to choose rock is 80.

Now,

In a survey of 90 students 40 choose hip hop.

So, 90 is equivalent to 40.

Thus, 360 is equivalent to $y.$

$\frac{90}{40} =\frac{360}{y} \\\\By\ cross\ multiplying\ we\ get:\\\\90y=14400\\\\Dividing\ both\ sides\ by\ 90\ we\ get:\\\\y=160.$

Therefore, 160 students expected to choose hip hop.

And,

In a survey of 90 students 30 choose country.

So, 90 is equivalent to 30.

Thus, 360 is equivalent to $y.$

$\frac{90}{30} =\frac{360}{z} \\\\By\ cross\ multiplying\ we\ get:\\\\90x=10800\\\\Dividing\ both\ sides\ by\ 90\ we\ get:\\\\x=120.$

Hence, 120 students expected to choose country.

Therefore, the students would be expected to choose rock be 80 or students choose hip hop be 160 or choose to country be 120.

Solve for h. -3(3h – 1) ≤ -7h – 5

bezimeni [28]

-3(3h-1)≤-7h-5
-9h+3≤-7h-5
-9h+7h≤-5-3
-2h≤-8
h≥4
Sign changes because you multiply with negative both sides.
