Answer:
The answer is D. Vertex at (-7,-9).
Step-by-step explanation:
The equation is in vertex form, so you take the opposite of x and the constant stays the same. So, the opposite of 7 is -7 and -9 stays the same.
A consumer group is investigating the number of flights at a certain airline that are overbooked. They conducted a simulation to estimate the probability of overbooked flights in the next 5 flights. The results of 1,000 trials are shown in the following histogram.
Answer:
C. 0.446
Step-by-step explanation:
1-(0.114+0.332) = 0.446
The sum of the relative frequencies of the bars for 4 and 5 is 0.446.
The probability that atleast four of the next five flights will be overbooked is the sum of the probabilities of having 4 or 5 flights overbooked which is 0.446
The probability of having atleast 4 flights overbooked can be defined as :
P(X ≥ 5) = P(X = 4) + P(X = 5)
From the probability distribution displayed on the histogram :
P(X ≥ 5) = 0.332 + 0.114 = 0.446
Therefore, the probability of having atleast 4 flights overbooked ls 0.446

What is a fraction?A fraction is written in the form of p/q, where q ≠ 0.
Fractions are of two types they are proper fractions in which the numerator is smaller than the denominator and improper fractions where the numerator is greater than the denominator.
Let, The numerator of a fraction represents the number of games lost and the denominator represents the total number of games played.
Therefore, The fractions that represent this context for all the teams are,
1/3, 1/9, 1/4 and 1/10.
We know the value of a fraction increase with the same numerator and smaller and smaller denominator.
So, The fraction 1/10 has the least value which indicates that it is the best performer.

Answer:
time greater than 6 hours
Step-by-step explanation:
For this problem, we are given the rate at which the refrigerator's temperature increases and the rate at which the oven's temperature decreases along with the initial temperatures for both. Using this information, we can determine the amount of time that will need to pass for the two to have equal temperature, or pass each other in opposite directions of temperature. Let's write the inequality using the information:
40 + 5t > 340 - 45t
Let t be the amount of time passed in hours. So, we simply need to solve the inequality for t.
40 + 5t > 340 - 45t
40 + 50t > 340
50t > 300
t > 6
Given this information, we know that after 6 hours have passed, the temperature of the fridge and oven will be equal. So we can say that any time greater than 6 hours, the fridge will have a higher temperature than the oven.

If l is parallel to m, solve for x and y.
Answer:
x=17, y=9
Step-by-step explanation:
(5x - 38)° = (3x - 4)°
2x = 34
x=17
(5(17)-38))=47
90°+47°+(7y-20)=180°
7y-20=43°
y=9
The value of x is 17 and y is 9.
What are the properties of parallel lines?Following are the properties of parallel lines,
The pairs of vertically opposite angles are equal.The pairs of corresponding angles are equal.The pairs of alternate exterior angles are equal.The pairs of alternate interior angles are equal.Given:
<1 = 7y -20
<2 = 5x - 38
<3 = 90
exterior angle = 3x -4
Using alternate interior angle
5x - 38 = 3x-4
2x = 34
x=17
So, <2 = (5(17)-38))
<2 =47
Using angle sum property
90°+47°+(7y-20)=180°
7y-20=43°
y=9
Hence, the value of x is 17 and y is 9.

Step-by-step explanation:
Given that J is the center of the ∆SUZ, therefore, J is the centroid of the ∆.
According to the centroid theorem, thus:
Centroid J will divide VS into VJ and SJ into the ratio of 1 : 2.
This means, SJ is twice the length of VJ.
Therefore, given that VJ = 3, thus:

What is the fundamental principle of multiplication?Multiplication is the mathematical operation that is used to determine the product of two or more numbers. If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.
We need ot find that 678 is divisible by 2, 3, and 6.
WE can see 678 is even, so it's divisible by 2
Now, the sum of digits are 6+7+8 = 21, which is divisible by 3, so 678 is divisible by 3
Since 678 is divisible by both 2 and 3, then it has to be divisible by 6
Using the divisibility rules, we can conclude that 678 is divisible by 2, 3, and 6.

Answer:
y -8 = 8/5(x +2)y = 8/5x +56/58x -5y = -56Step-by-step explanation:
Since you're given a point and slope, it is convenient to start with that form.
Point-slope form
y -k = m(x -h) . . . . . line with slope m through point (h, k)
y -8 = 8/5(x +2) . . . point-slope equation
__
Slope-intercept form
y = mx + b . . . . . line with slope m and y-intercept b
The above equation can be rearranged to this form.
y = 8/5x +16/5 +8
y = 8/5x +56/5 . . . . . slope-intercept form
__
Standard form
ax +by = c
Multiplying by 5 and subtracting the y-term gives the general form equation ...
5y = 8x +56
8x -5y +56 = 0
8x -5y = -56 . . . . . . add -56 to put into standard form
