0.02% would be of choosing a blue and a yellow card because there 16 cards so you are only choosing two cards

total cards = 16

total number of ways of choosing two cards randomly = 16C2 where nCr = n!/r!

number of ways of choosing blue card = 4C1

number of ways of choosing yellow card = 2C1

Probability = favorable outcomes / total outcomes

probability of choosing blue card and yellow card = 4C1  * 2C1 /16C1

= 1/15 = 0.066

A student studied 18 hours in one week. What is the total number of hours he will have to study during the next week in order to
REY [17]

Answer:

Step-by-step explanation:

[(2 hours)/(1 day)](14 days)=(18+x)hours

Let's note that the unit of day is in the numerator and denominator.  It cancels

[(2 hours)/(1 day)](14 days)=(18 hours)+(x hours)

(2 hours)(14)=(18+x)hours

Let's note that the unit of hours is in the numerators of both sides of the equation.  It cancels

(2 hours)(14)=(18+x)hours

(2)(14)=18+x

28=18+x

10=x

HE WILL HAVE TO STUDY 10 HOURS.

What do you need to know about two figured to be convinced that the two figures are congruent?
MrRissso [65]
It depends on what the figure looks like. You could have SSS is If three sides of one triangle are congruent to three sides of another triangle, then the triangles are congruent. As you can see, the SSS Postulate does not concern itself with angles at all.
SAS is have two triangles where we know two angles and the included side are equal.
ASA If two angles and the included side of one triangle are congruent to the corresponding parts of another triangle, then the triangles are congruent
Idk what the figures you are talking about but I gave u some for triangles. If you comment back I can help u if you give me the figures you are talking about

Suppose that the length of a certain rectangle is four centimeters more than three times its width. If the area of the rectangle
Oksana_A [137]

Answer:  The length and width of the rectangle are 19 cm and 5 cm respectively.

Step-by-step explanation:  Given hat the length of a rectangle is four centimeters more than three times its width and the area of the rectangle is 95 square centimeters.

We are to find the length and width of the rectangle.

Let W and L denote the width and the length respectively of the given rectangle.

Then, according to the given information, we have

L=3W+4~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)

Since the area of a rectangle is the product of its length and width, so we must have

A=L\times W\\\\\Rightarrow 95=(3W+4)W\\\\\Rightarrow 3W^2+4W-95=0\\\\\Rightarrow 3W^2+19W-15W-95=0\\\\\Rightarrow W(3W+19)-5(3W+19)=0\\\\\Rightarrow (W-5)(3W+19)=0\\\\\Rightarrow W-5=0,~~~~~3W+19=0\\\\\Rightarrow W=5,~-\dfrac{19}{3}.

Since the width of the rectangle cannot be negative, so we get

W=5~\textup{cm}.

From equation (i), we get

L=3\times5+4=15+4=19~\textup{cm}.

Thus, the length and width of the rectangle are 19 cm and 5 cm respectively.
