Answer:
0.1667 = 16.67%.
Step-by-step explanation:
We already know that the card drawn is blue, so now we need to check the value of the card.
The blue cards have 6 possibilities of values (2, 3, 4, 5, 6 or 8), and the number 4 appears only 1 time, so the probability of the blue card having the value 4 is the number of times this value occurs by the number of possible values:
P = 1/6 = 0.1667 = 16.67%.

Determine whether the following system of equations has one solution, no solution, or an infinite number of solutions. Explain your reasoning.
2x - 4y = 10
7x - 9y = 12
Answer:
One solution. The lines do not have the same slope (so not parallel) and are not the same line (so not infinitely many solutions). It intersects at one point, therefore it has one solution.

The formula to convert °F to °C is C = C equals StartFraction 5 Over 9 EndFraction left-parenthesis F minus 32 right-parenthesis.(F – 32).
Convert 50°C to °F.
10°F
20°F
122°F
132°F
The temperature in degree Fahrenheit is (c) 122
The function is given as:
[tex]C = \frac 59(F - 32)[/tex]
When the temperature is 50 degrees Celsius, it means that:
C =50
Substitute 50 for C in [tex]C = \frac 59(F - 32)[/tex]
[tex]50 = \frac 59(F - 32)[/tex]
Multiply through by 9
[tex]450 = 5(F - 32)[/tex]
Divide both sides by 5
[tex]90 = F - 32[/tex]
Add 32 to both sides
[tex]F = 90 +32[/tex]
[tex]F = 122[/tex]
Hence, the temperature in degree Fahrenheit is (c) 122

In a survey of 2 comma 3002,300 people who owned a certain type of car, 1 comma 2651,265 said they would buy that type of car again. What percent of the people surveyed were satisfied with the car?
Answer:
55% of the people surveyed were satisfied with the car
Step-by-step explanation:
The proportion of people surveyed who were satisfied with the car is the number of people who said they would buy that type of car again divided by the total number of people survied.
The percentage is the proportion multiplied by 100.
We have that:
2,300 people surveyed
1,265 said they would buy that type of car again.
1265/2300 = 0.55
0.55*100 = 55%
55% of the people surveyed were satisfied with the car

Ribbon Color Number of Times Picked pink 10 yellow 20 blue 40 white 30 The relative frequency of picking a pink ribbon is . The relative frequency of picking a white ribbon is . It is most likely that the number of ribbons in the box is the highest. It is most likely that the number of ribbons in the box is the lowest
Answer:
1. 0.1
2. 0.3
3. blue
4. pink.
Step-by-step explanation:
Got it right, hope this helps! :)
The blue ribbon was picked the most with a relative frequency of 40%, which means it is most likely that there are more blue ribbons in the box than the other colors.
What is Probability?It is a branch of mathematics that deals with the occurrence of a random event.
The relative frequency of picking a pink ribbon is found by dividing the number of times a pink ribbon was picked by the total number of times Bob picked a ribbon:
Relative frequency of pink ribbon = 10/100 = 0.1 or 10%
Similarly, the relative frequency of picking a white ribbon is:
Relative frequency of white ribbon = 30/100 = 0.3 or 30%
To determine which ribbon color is most likely to be the highest or lowest, we can compare the relative frequencies.
The blue ribbon was picked the most with a relative frequency of 40%, which means it is most likely that there are more blue ribbons in the box than the other colors.
Conversely, the pink ribbon was picked the least with a relative frequency of 10%, which means it is most likely that there are fewer pink ribbons in the box than the other colors.
Hence, the blue ribbon was picked the most with a relative frequency of 40%, which means it is most likely that there are more blue ribbons in the box than the other colors.

Answer:a
Step-by-step explanation:
BD−→− bisects ∠ABC such that m∠ABD = (4x−5)∘ and m∠DBC = (3x+2)∘.
Find m∠ABC.
m∠ABC = ∘
Answer:
[tex]\angle ABC=(46)^{\circ}[/tex]
Step-by-step explanation:
Given: BD bisects [tex]\angle ABC[/tex]
[tex]\angle ABD=(4x-5)^{\circ}\\\angle DBC=(3x+2)^{\circ}[/tex]
To find: [tex]\angle ABC[/tex]
Solution:
A bisector of an angle divides it into angles of equal measures.
As BD bisects [tex]\angle ABC[/tex], [tex]\angle ABD=\angle DBC[/tex]
Put [tex]\angle ABD=(4x-5)^{\circ}\,,\,\angle DBC=(3x+2)^{\circ}[/tex]
[tex]\angle ABD=\angle DBC\\(4x-5)^{\circ}=(3x+2)^{\circ}\\4x-3x=2+5\\x=7^{\circ}[/tex]
So,
[tex]\angle ABD=(4x-5)^{\circ}=(4(7)-5)^{\circ}=(28-5)^{\circ}=(23)^{\circ}\\\angle DBC=(3x+2)^{\circ}=(3(7)+2)^{\circ}=(21+2)^{\circ}=(23)^{\circ}[/tex]
[tex]\angle ABC=\angle ABD+\angle DBC\\=(23)^{\circ}+(23)^{\circ}\\=(46)^{\circ}[/tex]
A bisector divides lines, angles and shapes into equal segments
The measure of angle ABC is 46 degrees
The given parameters are:
m∠ABD = (4x−5)∘ m∠DBC = (3x+2)∘Given that line BD is the bisector of angle ABC, it means that:
[tex]\angle ABD = \angle DBC[/tex]
and
[tex]\angle ABC = 2\times \angle ABD[/tex]
So, we have:
[tex]4x - 5 = 3x +2[/tex]
Collect like terms
[tex]4x - 3x = 5 +2[/tex]
Evaluate like terms
[tex]x = 7[/tex]
Recall that
[tex]\angle ABC = 2\times \angle ABD[/tex]
So, we have:
[tex]\angle ABC = 2 \times (4x - 5)[/tex]
Substitute 7 for x
[tex]\angle ABC = 2 \times (4\times 7 - 5)[/tex]
[tex]\angle ABC = 2 \times (28 - 5)[/tex]
[tex]\angle ABC = 2 \times 23[/tex]
[tex]\angle ABC = 46[/tex]
Hence, the measure of angle ABC is 46 degrees

To solve the problem, we need to write each fraction in decimal form.
Notice that each denominator is 10 based, which means we only have to move the decimal point according to the total number of zeros have the denominators. If the denominator is 10, we move the decimal point one spot to the left, if the denominator is 1000, we move the decimal point three spots to the left, and so on.
