Answer:
95°
Step-by-step explanation:
<QRT = <PRS [Vertically Opposite Angles]
=> 4x + 15° = 3x + 35°
=> 4x - 3x = 35 - 15
=> x = 20
Hence, as value of x is 20 so <QRT is,
<QRT = 4x + 15° = 4 × 20 + 15
= 80 + 15 = 95° (Ans)

Identify if it's an independent or dependent event and write the probability as a fraction * What is the probability that from a normal 52 card deck, you randomly draw a 3, and then without replacing the 3, you draw the Queen of Hearts?
Answers
Answer: 0.151 percent
Step-by-step explanation:
The probability of any particular outcome is
(number of possible successful outcomes) / (number of total possibilities)
-- On the first draw, there are 52 possible total outcomes, and
only 4 that are successful ... drawing a 3 .
The probability of drawing a 3 from a full deck is ( 4 / 52 ).
-- On the second draw, there are 51 possible total outcomes (the first
card you drew stayed out), and only one is successful ... drawing the
queen of hearts.
The probability of this particular outcome is ( 1 / 51 ).
-- The probability of both of them is
( 4 / 52 ) x ( 1 / 51 ) =
( 4 / 2,652 ) = about 0.151 percent.

Answer:
= 1.156 × 10^9
(scientific notation)
= 1.156e9
(scientific e notation)
= 1.156 × 10^9
(engineering notation)
(billion; prefix giga- (G))
= 1156000000
Step-by-step explanation:
Simply subtract A from B = 1,156,000,000 and convert the answer to scientific notation.
Answer:
D. 1.156 times 10^9
First we subtract the difference,
1,300,000,000 - 144,000,000 = 1156000000
Next, we find the number 1156000000 written in scientific notation.
Step 1
To find a, take the number and move a decimal place to the right one position.
Original Number: 115,600,000
New Number: 1.15600000
Step 2
Now, to find b, count how many places to the right of the decimal.
New Number: 1 . 1 5 6 0 0 0 0 0
Decimal Count: 1 2 3 4 5 6 7 8
There are 8 places to the right of the decimal place.
Step 3
Building upon what we know above, we can now reconstruct the number into scientific notation.
Remember, the notation is: a x 10b
a = 1.156 (Please notice any zeroes on the end have been removed)
b = 8
Now the whole thing:
1.156 x 108
Step 4
Check your work:
108 = 100,000,000 x 1.156 = 115,600,000
Thus, 115,600,000 written in scientific notation is 1.156 times 10^9 estimated.
C-3d = 11
-2c + 3d = -16
Answers
This looks like a system of equations:
We should solve for c on the first equation because we can substitute for c. There are a lot of ways we can do a system of equations, but I will do this.
c - 3d = 11
+3d +3d
c = 11 +3d
Now we can substitute.
-2(11+3d) + 3d = -16
solve
-22 + -6d + 3d = -16
-22 + -3d = -16
+22 +22
-3d = 6
/-3 /-3
d = -2
So we have found d. We can solve for c.
c - 3(-2) = 11
c + 6 = 11
-6 -6
c = 5
Now we know both D and C. d=-2 and c=5

Answers
Answer:
x < -10
Step-by-step explanation:
Given the inequality 5 - 3x > 35
Subtract 5 from both sides
5 - 3x - 5> 35 -5
-3x > 30
Divide both sides by -3
-3x/-3 < 30/-3
x < -10 (note the change is sign)
hence the correct solution is x < -10

There are 48 students in a school play. The ratio of boys to girls is 5 : 7. How many more girls than boys are in the play?
Pls help me
Answers
Answer:
There are 8 more girls than boys.
Step-by-step explanation:
Ratios are easier to read as fractions (at least to me), so 5:7 would be 5/7. When you multiply both the top and the bottom by 4, you get 20/28, meaning that there are 20 boys and 28 girls. 28-20=8, so there are 8 more girls than boys.

The newsstand at the corner of Manilla Avenue and GreenTree Rd. in GreenTree sells the daily edition of The Pittsburgh Press. The number of papers sold each day follows a normal probability distribution with a mean of 600 copies and a standard deviation of 15 copies. You want to find the probability of selling more than 625 newspapers on any given day. What is the Excel Command
Answers
Answer:
1 - NORM.DIST(625, 600, 15 ,TRUE)
Step-by-step explanation:
Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
In Excel:
We use the norm.dist command.
NORM.DIST(x, mean, standard_dev ,cumulative)
x is the tested value, mean and standard_dev are the mean and the standard deviation, while cumulative we use true to find a probability of a value lower than x, so for a value higher than x, we use:
1 - NORM.DIST(x, mean, standard_dev ,TRUE)
Mean of 600 copies and a standard deviation of 15 copies.
mean = 600, standard_dev = 15
You want to find the probability of selling more than 625 newspapers on any given day.
x = 625
What is the Excel Command
1 - NORM.DIST(625, 600, 15 ,TRUE)
