Probability of picking blue marble = \frac{4}{5}

Step-by-step explanation:

Given,

Number of blue marbles = 4

Number of red marble = 1

Total number of marbles = 5

To find the probability of picking blue marble

Formula

Probability of an event = (number of occurrence of an event) ÷ (total number of events)

So,

Probability of picking blue marble = \frac{4}{5}

Answer:

We just need the equations to equal the same, which is y.

5+1.10x=y

3+1.50x=y

5+1.10x= 3+1.50x

Let's get x by itself by subtract 3 from both sides.

2+1.10x= 1.50x

Now subtract 1.10x from both sides.

2= 0.4x

Now divide each side by 0.4

5=X

So, at 5 games they're the same cost. Let's find the cost.

5+1.1(5)= 5+5.5=10.50

3+1.5(5)=3+7.5= 10.50

So, at 5 games, they are $10.50.

Hope this helps! :)

navik [9.2K]

Answer:

d= 12.50 miles

Step-by-step explanation:

Kinematic equation of uniform motion (constant speed) :

v= d/t  Formula (1)

v: velocity in miles per hour (mph)

d: distance in miles

t: time in hours

Data

v= 50 mph

t= 0.25 hours

Problem development

We replace data in formula (1)

50 mph=d/0.25 hour

50 \frac{miles}{hour} = \frac{d}{0.25 hour}

d= 50\frac{miles}{hour} *0.25 hour

d= 12.5 miles

d= 12.50 miles

What is the smallest angle of rotational symmetry for a square
mars1129 [50]

When we rotate a figure and there is no change in the shape of the figure then it has rotational symmetry.

We know that the order of rotation for a square is 4.

Hence, we have \frac{360}{4} =90^{\circ}

Thus, the angle of rotational symmetry of square are

90^{\circ}, 180^{\circ}, 270^{\circ}

Hence, the minimum angle  of rotational symmetry is  90^{\circ}

Therefore, the minimum angle of rotational symmetry for a square is 90 degrees.
