Answer:
12.5%
Step-by-step explanation:
Total card = 52
Total number of red card = 26
So, Probability of first card is red = [tex]\frac{26}{52}[/tex] or [tex]\frac{1}{2}[/tex]
Total number of diamond card = 13
So, probability of second card is diamond = [tex]\frac{13}{52}[/tex] or [tex]\frac{1}{4}[/tex]
So, probability that the first card is a red card and the second is a diamond can be calculated as follows,
Probability(first card, second card) = [tex]\frac{1}{2}[/tex] × [tex]\frac{1}{4}[/tex] = [tex]\frac{1}{8}[/tex] or 0.125
Probability(first card, second card) = 0.125 or 12.5%

Need those done by 33 minutes you have to use system of equations substitution thank you
Answer:
1. y=4
y=x+7
4=x+7
x= -3 , y= 4
2. y=3x
y=x+5
3x=x+5
2x=5
x=5/2 or 2.5
y= 3(5/2)
y= 15/2 or 7.5
x= 2.5, 7= 7.5
Answer:
1. x= -3 2. x= 5/2
Step-by-step explanation:
You need to substitute the second y equation given into the first one to find x. Then get x by itself on one side.
1. 4= x + 7
-7 -7
-3 = x
x= -3
2. 3x= x + 5
-x -x
2x= 5
(2x= 5) /2
x= 5/2

Why does b have to be positive in exponential functions and why can’t it be 1?
Answer:
Well, "b" is just a variable. It's not really the function. I'm not quite sure what your asking. It can't be 1 because it can't. Math was founded on these mathematical laws. Consider talking to your teacher about this for further explanation.

An initial deposit of $1,000 is made into a savings account that is compounded continuously at 3% interest. How much money will be in the account after 18 years?
Answer:
$1700
Step-by-step explanation:
Given data
Principal P=$1000
Rate r= 3%
Time T= 18years
Required
The final amount A
The expression for the compound interest is
A= P(1+r)^t
substitute
A=1000(1+0.03)^18
A=1000(1.03)^18
A= 1000*1.70
A=$1700
Hence the final amount after 18 years is $1700

x = 8
Step-by-step explanation:
The marked angles are alternate interior angles, so are congruent.
8x -4 = 60
8x = 64 . . . . . . . . . . add 4 to both sides
x = 64/8 = 8 . . . . . . divide both sides by 8

There are 100 coins with a total value of $10.15. How many quarters do you have? How many dimes do you have?
9514 1404 393
Answer:
99 dimes1 quarterStep-by-step explanation:
If all 100 coins were dimes, the value would be $10.00. Each dime traded for a quarter adds $0.15 to the value.
The actual value of the coins is $10.15 -10.00 = $0.15 more than it would be for all dimes. This indicates 1 dime has been traded for a quarter.
There are 99 times and 1 quarter.

g(x) = x2 - 4x +7
Find: (fog)(x)
Answer:
fog(x)= -4x+11
Step-by-step explanation:
Here,
f(x) = 2x - 3
g(x) = 2x - 4x +7 = -2x+7
fog(x)= f(-2x+7)
= 2(-2x+7)-3
= -4x+14-3

What is the area of this regular hexagon that has been divided into six congruent triangles?
336 cm2
242 cm2
168 cm2
84 cm2
The area of this hexagon that has been divided into six congruent triangles will be 168 cm².
What is a hexagon?A closed two-dimensional polygon with six sides is what is known as a hexagon in geometry.
Types of Hexagons
1. Regular Hexagon ⇒ It is a regular hexagon when the lengths of all the sides and the measures of all the angles are equal.
2. Irregular Hexagon ⇒ The length of the sides and the measure of the angles are not equal in an irregular hexagon.
Given that hexagon with a side of 7cm and the height of each triangle is 8cm.
Area of one triangle = (1/2)× base × height
⇒ (1/2) × 7 × 8
⇒ 28 cm²
Now the area of the complete hexagon is 28 × 6 = 168 cm² hence, the area of the given hexagon will be 168 cm².
