Answer:

  66%

Step-by-step explanation:

The categories are mutually exclusive, so we have ...

  P(≤30) = P(1–10) +P(10–20) +P(20–30) = 5% +16% +45%

  P(≤30) = 66%

The probability is 66% that a randomly chosen student has visited 30 or fewer states.

Answer:

.55

Answer:

64

Step-by-step explanation:

Given that,

Buddy painted (1/5) of the 320 nutcrackers.

We need to find how many nutcrackers did buddy paint. It can be calculated by finding (1/5) of 320.

[tex]x=\dfrac{1}{5}\times 320\\\\=64[/tex]

Hence, he painted 64 nutcrackers.

Step-by-step explanation:

Lin bought x grams of sugar.

Jada bought 3⁄4 more than  Lin bought.

The equation:

Answer: This one is equal to what we were looking for.

4 × 5c = 20 - 8d = 12

Step-by-step explanation:

(20c - 8d = 12) so we are look for an expression that is equal to 20c 8d and 12

2 × 10c = 20 + 4d = 24

4 × 5c = 20 - 8d = 12

4 × 5c = 20 - 2d = 18

c20 - 8d = 12

Answer:

(X + 6 ) ×2

It is given in the question that the no. is increased by 6 so if we take the no. as X the new no. formed is X + 6 now on doubling it the answer we get is. 2(X+6)

The correct algebraic expression is option C) 2(x + 6) matches the expression that represents the number x increased by 6, and then doubled.

Given that : "a number x increased by 6, and then doubled," perform the operations in the correct order.

To represent the given scenario of "a number x increased by 6, and then doubled," required to follow the steps:

Step 1:

Let the number be x.

Increase the number x by 6:

x + 6.

Step 2 :

Double the result by multiply the expression:

(x + 6)2,

Remove brackets by BODMASS gives:

2* x + 2 *6

On multiplying gives:

2x+12

ON taking common factors 2 gives:

2(x+6)

Therefore, the correct expression is 2(x + 6).

Option C) 2(x + 6) matches the expression that represents the number x increased by 6, and then doubled.

Answer:

1. (3,19) and (-1,-13)

  to find the slope you need to do [tex]\frac{y2-y1}{x2-x1}[/tex]

Hence [tex]\frac{-13-19}{-1-3}[/tex]= 32/-4=-8

2. Take two points on the graph:

(-2,3) and (1,0)

Know that to calculate the slope you do

[tex]\frac{rise}{run}[/tex]= 4/2= 2

3. To find the slope in a table you need to choose any two points and utilize the following formula: [tex]\frac{y2-y1}{x2-x1}[/tex]= [tex]\frac{-16-(-8)}{2-1}[/tex]=-8/1= -8

4. Like in #1 we take the two points and plug it into the formula:

[tex]\frac{8-(-10)}{0-9}[/tex]=18/-9= -2

Step-by-step explanation:

Answer:

(1) x^2 is greater than 1.

(2) x is greater than -1.

(1) x^2 is greater than 1 --> x2>1x2>1 --> x<−1x<−1 or x>1x>1. Sufficient.

(2) x is greater than -1 --> x>−1x>−1. Not sufficient.

Answer:

6+2i

Step-by-step explanation:

(5+7)/2 = 6

(-2+6)/2 = 2

Answer:

x = 6

Step-by-step explanation:

The given statement is "Eighteen is six less than four times a number".

Let the number be x.

ATQ,

18 = 4x-6

Taking like terms together,

18+6 = 4x

24 = 4x

x = 6

Hence, the value of x is 6.

Answer:

(5,0) and (0,3) have a slope of -3/5

Step-by-step explanation:

Here, we want to state a pair of points that have a slope of -3/5

Mathematically, we can have the slope of a straight line calculated as;

m = y2-y1/(x2-x1)

This could give points like (5,0) and (0,3)

Answer:

1/2

Step-by-step explanation:

From the question, there are 13 cards of heart and 13 card of club in each suit in each deck.

P(drawing heart) = 13/52

P(drawing club) = 13/52

And we know total standard pack =52

P(drawing a heart or a club)

= number of favourable outcome/ total Number of outcome

P( drawing heart or club) =( 13+13)/52

=26/52

=1/2

Answer:

5 units

Step-by-step explanation:

Since The X coordinate of a point P on X axis is 4 and the y coordinate of a point Q on y axis is 3 the points are

P (4 , 0) and Q(0 , 3)

The formula to calculate distance between two points

[tex]PQ=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2} \\PQ=\sqrt{(0-4)^2+(3-0)}\\PQ=\sqrt{(4)^2+(3)^2}\\PQ=\sqrt{16+9} \\PQ=\sqrt{25} \\PQ=5\ units\ \\[/tex]

IMPORTANT!

As we take the square root of 25 we get two values +5 and -5 we always take the positive value because distance can never be negative.
