Shelby has a $5 gift card to an online music store. She downloads songs that cost $1.20 each. What equation models the total amount of money Shelby spends y if she downloads x songs?
y = 5x + 1.20
y = 5x + 1.20
y = -5x + 1.20
y = -5x + 1.20
y = 1.20x - 5
y = 1.20x - 5
y = 1.20x + 5

Find an angle with a positive measure and an angle with a negative measure that is coterminal with each angle 210° and - 120°
Answer:
For angle of 210°, coterminal angles are; 570° and -150°.
For angle of -120°, coterminal angles are; 240° and -480°
Step-by-step explanation:
Since we are asked to angle find angle that's coterminal, we will add/ subtract 360° from each angle respectively to get that because coterminal angles are defined as those that share the same terminal side. Thus;
For angle of 210°, coterminal angles are;
>> 210° + 360° = 570°
>> 210° - 360° = - 150°
For angle of -120°, coterminal angles are;
>> - 120° + 360° = 240°
>> - 120° - 360° = - 480°

THE CORRECT ANSWER is 25 Cm³
Explanation:
Let's consider the vertical block first, having height 8cm, length 1 cm, width 2cm.
Hence the volume of that block = l.w.h = 8×2×1 = 16 cm³
Coming to the horizontal block, having height 3cm, width 3cm, & length 1 cm.
Hence the volume of that block will be = 3×3×1 = 9 cm²
The total volume of irregular figure = Volume of vertical block + horizontal block = 16+9 = 25 cm³

Which number in the equation below represents a vertical shift?
f (x) = -|x-5| +3
A)-5
B)3
C)5
D)-1
Answer:
B) 3
Step-by-step explanation:
The (-) represents a flip over the X-Axis.
The |X-5| represents a Horizontal shift right because it's in between the parenthesis.
The 3 represents a positive vertical shift upwards.

The point (-2, 7) is graphed on a coordinate plane. The point is located 2 units
the origin and 7 units
the origin.
Hi there!
»»————- ★ ————-««
I believe your answer is:
Two units left, 7 units up.
»»————- ★ ————-««
Here’s why:
Moving a point to the left would have a negative 'x' value. Since the point has '-2', it is two units left from the origin.The positive value of 7 in the 'y' value means that the point is 7 units up from the origin.»»————- ★ ————-««

Answer:
x = 91
y = 98
Your answer is F.
Step-by-step explanation:
Since a straight angle is 180° you have to subtract 89 from 180 and 82 from 180.
180 - 89 = 91
180 - 82 = 98

The State Department of Weights and Measures is responsible for making sure that commercial weighing and measuring devices, such as scales, are accurate so customers and businesses are not cheated. Periodically, employees of the department go to businesses and test their scales. For example, a dairy bottles milk in 1-gallon containers. Suppose that if the filling process is working correctly, the mean volume of all gallon containers is 1.00 gallon with a standard deviation equal to 0.10 gallon. The department's test process requires that they select a random sample of n = 9 containers. If the sample mean is less than 0.97 gallons, the department will fine the dairy. Based on this information, what is the probability that the dairy will get fined even when its filling process is working correctly?
A. 0.90
B. Approximately 0.3159
C. About 0.1841
D. Approximately 0.382
Answer:
B. Approximately 0.3159
Step-by-step explanation:
To solve this question, we need to understand the normal probability distribution, and the central limit theorem.
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 z-score 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 p-value, we get the probability that the value of the measure is greater than X.
Central Limit Theorem
The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].
For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.
The mean volume of all gallon containers is 1.00 gallon with a standard deviation equal to 0.10 gallon.
This means that [tex]\mu = 1, \sigma = 0.1[/tex]
Sample of 9:
This means that [tex]n = 9, s = \frac{0.1}{\sqrt{9}}[/tex]
If the sample mean is less than 0.97 gallons, the department will fine the dairy. Based on this information, what is the probability that the dairy will get fined even when its filling process is working correctly?
This is the pvalue of Z when X = 0.97. So
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
By the Central Limit Theorem
[tex]Z = \frac{X - \mu}{s}[/tex]
[tex]Z = \frac{0.97 - 1}{\frac{0.1}{\sqrt{9}}}[/tex]
[tex]Z = -0.9[/tex]
[tex]Z = -0.9[/tex] has a pvalue of 0.1841.
The correct answer is given by option B.
Answer:
Option C
Step-by-step explanation:
Given
Probability of Mean value less than 0.97
= Mean value -1/(0.1/sqrt (9))
Substituting the given values, we get -
Probability of Mean value less than 0.97
= 0.97 -1/(0.1/sqrt (9))
= 0.97-1/(0.1/3)
= 0.1841
Hence, option C is correct

Answer:
1.) x=-7
2.) x= -8
3.) x=13
4.) x=2
Step-by-step explanation:
ur lucky idc
1. 4x = -28
By dividing both sides of this equation by 4, we see that x = -7.
2. x - (-6) = -2
Note that x - (-6) is equal to x + 6. To solve the equation x + 6 = -2, subtract 6 from both sides to see that x = -8.
3. -x + 4 = -9
First, subtract 4 from both sides to get that -x = -13. Then, multiply both sides by -1 to see that x = 13.
4. -3x + 7 = 1
First, subtract 7 from both sides to get that -3x = -6. Then, divide both sides by -3 to see that x = 2.

If 1/8 of my money is $80. What is 50 % of my money
Answer:
$320
Step-by-step explanation:
An easy way to solve this problem is to undo the operations, Find the total amount of money, and then find half of the amount. Since (80) is ([tex]\frac{1}{8}[/tex]) the total amount of money, one has to multiply (80) by (8) to find the total amount of money.
(80) * (8)
= 640
Now one is asked to find (50%) of the money. It is known that (50%) is equivalent to (0.5), therefore multiply (640) by (0.5) to find how much (50%) of the money is.
(640) * (0.5)
= 320

Write the slope-intercept form of the equation of the line.
Answer:
Step-by-step explanation:
slope-intercept form: y = mx + b
by inspection ( just looking at the graph) we can see that the line goes thur the +2 on the y axis. so b=2 and we can also see that the line runs up hill so a positive slope and it's going up one for ever one over. So it has a positive 1 slope.
y = 1x + 2
y = x + 2
