When given a set of cards lying face down that spell M, A, T, H, F, A, N, determine the probability of randomly drawing a consonant.
six halves
six sevenths
five sevenths
two sevenths
Answer: five sevenths
Step-by-step explanation:
To determine the probability of randomly drawing a consonant from the set of cards, we first need to identify the consonants in the given letters: M, A, T, H, F, A, N.
From this set of letters, the consonants are M, T, H, F, and N. There are 5 consonants out of a total of 7 letters.
To calculate the probability, we divide the number of favorable outcomes (drawing a consonant) by the total number of possible outcomes (drawing any letter).
The probability of randomly drawing a consonant is:
Number of favorable outcomes: 5 consonants
Total number of possible outcomes: 7 letters
Therefore, the probability of randomly drawing a consonant is 5/7.
Expressing it as a fraction, the probability is five sevenths.
Therefore, the correct answer is five sevenths.

(4²) - (6 ÷2)+3(16 - 3) + 313 + 3
(4²) - (6 ÷2)+3(16 - 3) + 313 + 316
Hence, the correct answer is 16

6 possible outcomes
Step-by-step explanation:
Given:
Flip a coin
Draw a marble at random from a bag containing two purple marbles and one white marble
To Find:
The possible outcomes = ?
Solution:
By Flipping a coin, we have two outcomes, either head or tail
For each of these outcomes we will either tale any one of the balls from the bag
So possible outcomes will be
Head - purple ball
head -purple ball
Head -white ball
Tail - purple ball
Tail -purple ball
Tail -white ball
So there are 6 possible outcomes.
At summer camp, 60 students are divided in two groups for swimming or hiking. Each camper flips a coin, where heads represents swimming and tails represents hiking.

Answer:
The theoretical probability of swimming, P(swimming), is 26 over 60, but the experimental probability is one half.
Step-by-step explanation:
How to calculate the probability
The ratio between the number of favorable events and the total number of conceivable outcomes is known as the theoretical probability.
The experimental probability can be calculated mathematically using the following formula: Probability of an Event P(E) = Number of Times an Event Occurs / Total Number of Trials.
The experimental probability will be:
= Frequency for swimming / Total frequency
= 26 / 60

What is a possible explanation for why median and interquartile range are the preferred measures of center and variation when a data set contains outliers?
Answer: The median is the middle number in a data set, better than a mean because in a mean, those outliers are part of the average. The IQR is the middle 50% of a data set, better than a regular range because it excludes any outliers on either end.

The median and interquartile range are often preferred measures of center and variation when a data set contains outliers because they are robust to outliers.
What is interquartile range?The interquartile range (IQR) is a measure of data set variability or spread. It is the difference between a distribution's third and first quartiles (Q3), and it represents the range of the middle 50% of the data.
When a data set contains outliers, the median and interquartile range are often preferred measures of center and variation because they are robust to outliers.
Outliers are extreme values that are far outside the range of the remaining data points and can have a significant impact on measures of center and variation such as the mean and standard deviation.
Thus, when there are outliers in a data set, using the median and IQR as measures of center and variation, respectively, can provide a more accurate representation of the data set's central tendency and variability than using the mean and standard deviation, which are more sensitive to outliers.

What is the circumference of the circle in terms of π?
circle with a segment drawn from one point on the circle through the center to another point on the circle labeled 6 yards
36π yards
18.84π yards
6π yards
3π yards
Answer:
Therefore, the circumference of the circle is 6π yards.
Step-by-step explanation:
The circumference of a circle can be calculated using the formula C = 2 * π * r, where r is the radius of the circle.
In this case, we have a segment drawn from one point on the circle through the center to another point on the circle labeled 6 yards, which is equal to the diameter of the circle. So, the radius of the circle is 6 yards / 2 = 3 yards.
Plugging this into the formula, we have:
C = 2 * π * 3 = 6 * π
Therefore, the circumference of the circle is 6π yards.

Chau is a software salesman. His base salary is $2300, and he makes an additional $50 for every copy of Math is Fun he sells.
Let P represent his total pay (in dollars), and let N represent the number of copies of Math is Fun he sells. Write an equation relating P to N. Then use this equation to find his total pay if he sells 26 copies of Math is Fun.
Answer: hope this helps ♡
P = $3600
Step-by-step explanation:
P = total pay
N = num of 'Math is Fun'
P = $2300 + $50(N)
P = $2300 + $50(26)
P = $2300 + $1300
P = $3600

Step-by-step explanation:
The x shouldn't change. If this isn't correct, I apologize. But I'm sure I calculated this right.
The coordinates of the figure after a translation of 5 units up is U' ( -3 , 1 ) , M' ( -1 , 4 ) and L' ( -2 , 0 )
The coordinates of the figure after a translation of 3 units up is R' ( -4 , 0 ) , D' ( -4 , 4 ) , L' ( 0 , 3 ) and F' ( 0 , 0 )
What is Translation?A translation moves a shape up, down, or from side to side, but it has no effect on its appearance. A transformation is an example of translation. A transformation is a method of changing a shape's size or position. Every point in the shape is translated in the same direction by the same amount.
A translation in the coordinate plane moves every point on a figure a given distance in a given direction. The position of any point (x, y) on the figure changes to (x + a, y + b), where a and b are real numbers.
Given data ,
Let the translated figure be represented as A
Now , the coordinates of the figure are
a)
The coordinates of the figure are U ( -3 , -4 ) , M ( -1 , -1 ) and L ( -2 , -5 )
And , when the translation is up , the y coordinate increases by d units
The coordinates of the figure after a translation of 5 units up is U' ( -3 , 1 ) , M' ( -1 , 4 ) and L' ( -2 , 0 )
b)
The coordinates of the figure are R ( -4 , -3 ) , D ( -4 , 0 ) and L ( 0 , 0 ) and F ( 0 , -3 )
And , when the translation is up , the y coordinate increases by d units
The coordinates of the figure after a translation of 3 units up is R' ( -4 , 0 ) , D' ( -4 , 3 ) , L' ( 0 , 3 ) and F' ( 0 , 0 )
Hence , the translation is solved

Suppose that you know that angle t and angle s are supplementary, and that the measure of angle t = 3 times the measure of angle s.
How can you find the measure of angle t ?
Answer: 135 degrees
Step-by-step explanation:
Supplementary angles are those angles that sum up to 180 degrees. For example, angle 130° and angle 50° are supplementary angles because the sum of 130° and 50° is equal to 180°.
Using that, you know that angles t and s are equal to 180 degrees. You also know that angle t is 3 times the measure of angle s.
Therefore, we can create this equation.
3s + s = 180
4s= 180
s = 45
Angle s is 45 degrees.
180 - 45 = 135
Angle t is 135 degrees.

Step-by-step explanation:
SolutionThe solution is in the attached photo, do take note to solve this question, angles properties must be used.
Answer:
x=48°
Step-by-step explanation:
We can see the line at the top. 52°+y+59°=180° because these angles are supplementary angles. We can solve this problem:
52°+y+59°=180°
y=180-52-59
y=180-111
y=80-11
y=69°
because the angles in a triangle add up to 180°, y+63°+x=180°, or
69°+63°+x=180°
We can solve it from here:
69+63+x=180
120+12+x=180
132+x=180
x=180-132
x=80-32
x=48°

[tex](7a \cdot 5b) \div 6c \cdot 2d[/tex]
Step-by-step explanation:
If there is both multiplication and division in an expression and no parentheses, you start solving from left to right. Since in the expression [tex]7a \cdot 5b \div 6c \cdot 2d[/tex] you would start by solving [tex]7a \cdot 5b[/tex], (because it's at the leftmost part of the expression) it won't matter whether you put parentheses around [tex]7a \cdot 5b[/tex] or not. Therefore, the expression [tex](7a \cdot 5b) \div 6c \cdot 2d[/tex] is equivalent to [tex]7a \cdot 6b \div 6c \cdot 2d[/tex].
