4: likely

Step-by-step explanation:

Question 3:

the spinner has 1, 2, 3, 4, 5, 6

2, 4, 6 are all even number which is 3 / 6 = 1 / 2

so half a chance can be odd or half even possibility of landing

Question 4:

- 13 yellow

- 4 green

- 3 blue

total marbles: 13 + 4 + 3 = 20

yellow / total = 13 / 20

which is more than half of the marbles are yellow

When a coin is tossed ten times, the probability of getting a head will be 1/2.

In probability, one can either get a head or a tail. Therefore, when a coin is tossed ten times the probability of tossing a head will be:

= 5/10 = 1/2

In tossing one coin 100 times, the chances for tossing a head will be:

= 1/2 × 100 = 50

In tossing one coin 200 times, the chances for tossing a head will be:

= 1/2 × 200

= 100

In conclusion, the deviation for 10 tosses is 0.1

Answer:

-0.7071.

Step-by-step explanation:

The value of function sin 315 is -1/2.

Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles.

Sin 315 degrees can be found by using the unit circle.

The unit circle is a circle with the radius of one centered at the origin of a coordinate plane.

Every point on the unit circle is a point that is one unit away from the origin.

The unit circle is used to help find the exact values of the trigonometric functions at specific angles.

The angle 315 degrees is in the fourth quadrant of the unit circle, so the x-coordinate is negative and the y-coordinate is negative.

Using the x-coordinate, we can calculate the sine to be -1/2.

Hence, the value of function sin 315 is -1/2.

Explanation:

2(4) = 8 - 2 = 6

3(4) = 12 + 2 = 14

Answer:

12.

Square root = 37,

Step-by-step explanation:

40^2 = 1600

35^2 = 30 * 40 + 25 = 1225

So the requred square is between 35 and 40

38^2 = 1444

37^2 = 1369 - so its this one.

Required difference = 1381 - 1369 = 12.

Answer:

x = 2, y = 13, z = 1

Step-by-step explanation:

2 * 2 * 13 * 13 * 17 is equal to 2x * 13y * 17z.

knowing that 2x = 2 * x

therefore

2 * 2 * 13 * 13 * 17 * 1

2 * x * 13 * y * 17 * z

meaning that

x = 2, y = 13, z = 1

Step-by-step explanation:

Think of the < and > signs as arrow marks

Whichever direction the arrows pointing, that's where you should plot.

The line graph shown goes rightwards, so use the sign that looks like it's pointing right. (>)

Finally, don't use the greater than or equal to sign because the circle isn't colored in. This means that it doesn't include 10, only numbers higher than 10.

Product of 12 => 12x
is greater than => [tex]\geq[/tex]
24

so 12x [tex]\geq[/tex] 24

Answer:

c. 12x > 24

Step-by-step explanation:

Only one choice has the "greater than" symbol. It is C.

A number is the variable x.

The product of 12 and a number is 12 × x which is written simply as 12x.

12x is greater than 24.

The symbol for "greater than" is >.

Answer: c. 12x > 24

Step-by-step explanation:

we don't see all answer options.

but I am sure it must be b.

simply because the right graph shows that the curve goes through

(4, 0) and (-4, 0)

and

(0, 3) and (0, -3)

but if I am mistaken about b showing that, please pick the graph that shows this.

the reason is to think when is the x term being 1, when y = 0, and when is the y term being 1, when x = 0.

these are some "cornerstones" for the graph based on the functional definition.

Step-by-step explanation:

Using a system of equations, it is found that there are 10 baskets that hold 4 meals in the shop.

A system of equations is when two or more variables are related, and equations are built to find the values of each variable.

In this problem, the variables are given by:

There are 25 baskets in the shop, hence:

x + y = 25 -> x = 25 - y

They can hold a total of 70 meals, hence:

2x + 4y = 70

2(25 - y) + 4y = 70

2y = 20

y = 10

There are 10 baskets that hold 4 meals in the shop.

To determine the maximum number of pens he can buy, we need to consider the total discount of $70 and the cost of each pen, which is $9.

Assume he buys an "x" number of pens.

The total discount he receives can be calculated by multiplying the number of pens by the cost of each pen:

$9x

Based on, the shopkeeper agrees to give him a total discount of $70, so we have the equation:

$9x = $70.

To determine the maximum number of pens he can buy, we need to solve for "x".

Dividing both sides of the equation by $9:

x = $70 / $9.

x= 7.77.

Therefore, the maximum number of pens he can buy is 7.

Split up the -11c into -8c and -3c:

keeping in mind that perpendicular lines have negative reciprocal slopes, let's check for the slope of the equation above

[tex]y = \stackrel{\stackrel{m}{\downarrow }}{\cfrac{1}{2}}x+6\qquad \impliedby \begin{array}{|c|ll} \cline{1-1} slope-intercept~form\\ \cline{1-1} \\ y=\underset{y-intercept}{\stackrel{slope\qquad }{\stackrel{\downarrow }{m}x+\underset{\uparrow }{b}}} \\\\ \cline{1-1} \end{array}[/tex]

so then
