You pick a card at random. 4 5 6 7 What is P(less than 7)? Write your answer as a fraction or whole number.
Answers
Answer:
3/4 is less than 7.
Step-by-step explanation:
There are 4 numbers but there are only 3 less than 7.
The probability P(less than 7) is 3/4.
What is probability?Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one.
For the given situation,
The cards are numbered as s = {4,5,6,7}
⇒[tex]n(s)=4[/tex]
The event is probability of picking the cards less than 7
Cards less than [tex]7[/tex] , [tex]e=4,5,6[/tex]
⇒[tex]n(e)=3[/tex]
Probability of picking the card is given by [tex]p(e)=\frac{n(e)}{n(s)}[/tex]
On substituting the values,
⇒[tex]p(less than 7)=\frac{3}{4}[/tex]
Thus the probability P(less than 7) is 3/4.

Answers
Answer:
115 degrees
Step-by-step explanation:
We know that angle y is 45 degrees and angle z is 70 degrees so to find x, you do 180-45-70 to get 65 degrees.
Because W plus X has to equal 180 degrees, 180-65=115, so the answer is 115 degrees
Answer:
choice 3) W = 115 degrees
Step-by-step explanation:
all triangle interior angles add up to 180 degrees
180 = 45 + 70 + X
X = 65 degrees
Angle W is supplemental to angle X (angle W and angle X add up to 180 degrees.)
W = 180 - 65 = 115 degrees

72(3x-20) = 9(56)

x = 9
Answer:
9
Step-by-step explanation:
If you draw a segment parallel to a side of triangle that intersects two sides of the triangle, that segment divides the intersected sides into segments of proportional lengths.
9/72 = (3x - 20)/56
1/8 = (3x - 20)/56
3x - 20 = 1/8 * 56
3x - 20 = 7
3x = 27
x = 9

$5.09. a) How much money did she gain/lose with this stock?
b) What is her rate of return?
Answers
Tori's loss from the stock will be $28.29 and her rate of return will be -84.75%.
Since Tori bought one share of Macy's stock on Nov 1, 2016 for $33.38 and she sold it and the closing price for that day was $5.09, her loss will be;
= $5.09 - $33.38
= -$28.29
Her rate of return will be:
= -28.29/33.38 × 100
= -84.75%

5 subtracted from 3 times a number x gives 7.
Answers
Answer:
3x-5=7
3x=7+5
x=12/3
x = 4
Answer:
Step-by-step explanation:
3 times a number x: 3*x = 3x
5 subtracted from 3x = 3x - 5
Equation: 3x - 5 = 7
Solution:
Add 5 to both sides
3x - 5 + 5 = 7 + 5
3x = 12
Divide both sides by 3
3x/3 = 12/3
x = 4
In △ABC, G is the centroid and BE = 21. Find BG and GE.
Answers
Answer:
BG = 7, GE = 14Step-by-step explanation:
The centroid is the intercession of medians.
The centroid theorem states that the centroid is 2/3 of the distance from each vertex to the midpoint of the opposite side.
BE is the median and point G is 2/3 of the distance from E:
GE = 2/3BE = 2/3(21) = 14Then BG is:
BG = BE - GE = 21 - 14 = 7The answer is BG = 7, GE = 14
Answer:
the answer is BG=7,GE=14

Linda and Philip share £54 in the ratio 4:5. Find how much money each of them will recieve
Answers
Answer:
Linda has £24 and Philip has £30.
Step-by-step explanation:
Denote a variable to the amount of money Linda and Philip have:
Money Linda has = L
Money Philip has = P
L + P = 54
There is a ratio of 4:5 so for every £4 Linda has, Philip will have £5. When adding both values, 4+5, you get 9.
Divide the total amount of money by the sum of the ratio numbers so 54/9 which gives 6.
Multiply the number you get from the division by their respective ratios.
Linda = 6 * 4 = 24
Philip = 6 * 5 = 30
Add both numbers if you want to make sure the answer is correct.

What is the number system?A number system is defined as a way to represent numbers on the number line using a set of symbols and approaches. These symbols, which are known as digits, are numbered 0 through 9.
We have to determine the number that lies halfway between 16 and 38.
This is calculated by finding the average (or mean) of the two numbers. To do this, add the numbers together (16 + 38) and divide by 2.
⇒ 54/2
The result is 27.
Thus, the number that lies halfway between 16 and 38 is 27.
