Express 15 3/5 as a fraction in simplest form
Answer: 78/5
Step-by-step explanation:
To simplify this fraction, we should get rid of 15 in order to only have a numerator and a denominator. We would first multiply 15 with 5.
15 * 5 = 75
Then we would add 75 to 3.
75 + 3 = 78
We now have our numerator for our simplified fraction.
78/5

Answer: tan(pi+theta)=-9.9
Tan(2pi+theta)=-9.9
Step-by-step explanation:
By trigonometric expressions we conclude that the values of the tangent functions of the angles π + θ and 2π + θ radians are both equal to - 9.9.
How to calculate trigonometric functions from unit circle
A unit circle is a circle with a radius of a unit used to calculate the value of trigonometric functions associated to a right triangle. In this case, the tangent function for a point (x, y) is:
tan θ = y/x (1)
The trigonometric expression for the tangent of the sum of two angles:
[tex]\tan (\alpha + \theta) = \frac{\tan \alpha + \tan \theta}{1 - \tan \alpha \cdot \tan \theta}[/tex] (2)
Now we proceed to calculate the trigonometric expressions:
[tex]\tan (\pi + \theta) = \frac{\frac{-0.99}{0.1}+0}{1-\left(\frac{-0.99}{0.1}\right)\cdot (0)}[/tex]
[tex]\tan (\pi + \theta) = -9.9[/tex]
[tex]\tan (2\pi + \theta) = \frac{\frac{-0.99}{0.1}+0}{1-\left(\frac{-0.99}{0.1}\right)\cdot (0)}[/tex]
[tex]\tan (2\pi + \theta) = -9.9[/tex]
By trigonometric expressions we conclude that the values of the tangent functions of the angles π + θ and 2π + θ radians are both equal to - 9.9.

4 (2x - 3) -6 (3x + 4)
Answer:
-2x .(5x+18)
Step-by-step explanation:
please please help me
Answer:
a) Angle(A+B+C) = 180°
3x - 2° + x - 2° + 2x + 4° = 180°
6x = 180°
x = 30°
<A = 3(30°) - 2° = 88°
<B = 30° - 2° = 28°
<C = 2(30°) + 4° = 64°
b) at point Q
3y + 6y = 180°
y = 20°
<Q = 3(20°) = 60°
<S = 20°
x = 180° - (<S + <Q)
x = 180° - (80°)
x = 100°
<R = 100°

1. In the adjoining figure, p||q .Find the unknown angles.
Answer:
Step-by-step explanation:
d = 125 {corresponding angles are equal}
e + 125 = 180 {linear pair}
e = 180 - 125
e = 55
f = e {Vertically opposite angles}
f = 55
c = f {corresponding angles are equal}
c = 55
a = c {Vertically opposite angles}
a = 55
b =d {Vertically opposite angles}
b = 125
Answer:
a = 55°
b = 125°
c = 55°
d = 125°
e = 55°
f = 55°
Step-by-step explanation:
125 + e = 180
e = 180 - 125
e= 55°
e = f = 55°
f = a (being alternate angles)
a = c( being vertically opposite angles)
d = 125°(being corresponding angles)
d = b (being vertically opposite angles)

Step-by-step explanation:
Steven measures the weight of a random sample of 49 basset hounds the mean wait was 45.8 lb with a standard deviation of 3 lb using the alternative hypothesis that Miu is less than 45.8 Steven found a ztest statistic of -1.5 what is the p value of the test statistic
Answer: 0.067
Step-by-step explanation:
Look at chart, go to the row for the z-column for -1.5 and then the column 0, this value is 0.0668 or 0.067.
The p-value of the test statistic is approximately 0.0668.
Given that,
Steven measured the weight of a random sample of 49 basset hounds.
The mean weight of the sample was 45.8 lbs.
The standard deviation of the sample was 3 lbs.
Steven used an alternative hypothesis that the true mean weight is less than 45.8 lbs.
Steven found the z-test statistic of -1.5.
Based on the information provided,
We can see that Steven has conducted a hypothesis test to determine whether the true mean weight of basset hounds is less than 45.8 pounds.
To calculate the p-value for this test statistic,
Use a standard normal distribution table to determine the area under the curve to the left of the z-score of -1.5.
Using a standard normal distribution table,
Find that the area to the left of -1.5 is approximately 0.0668.
This means that there is a 6.68% chance of getting a sample mean of 45.8 or less assuming that the true population mean is actually 45.8.
Alternatively, we can use a calculator to find the p-value.
Using a calculator, we would input the z-score of -1.5 and the degrees of freedom (which is n-1, or 48 in this case) into the calculator.
This would give us a p-value of approximately 0.0668 as well.
Thus,
The p-value of the test statistic is approximately 0.0668.

on a number line, where would 4/10 be located? choose all answers that make a true statement.
Answer:
A and B only
Step-by-step explanation:
Number lines have smaller numbers on the left and larger numbers on the right. To determine the position of 4/10 on the number line, we just need to compare the value to the values in the answer choices.
a. 4/10 is equivalent to 2/5 (2/5 is just a simplified version of 4/10). If you multiple both the numerator and denominator of 2/5 by 2, you will get 4/10. If you do 4 divided by 10 and 2 divided by 5, you'll also see that they are both equivalent to 0.4. Hence, they have the same value and will be in the same place.
b. 3/10 is smaller than 4/10. In a case where the denominators of two fractions are the same, a smaller numerator would mean a smaller value. In addition, 3/10 is equivalent to 0.3 and 4/10 is equivalent to 4/10 so 0.3 is less than 0.4. That means 4/10 will be on the right of 0.3 because it's a larger number.
c. Using the same logic as part b, 2 is less than 4. That means 2/10 is less than 4/10, so 4/10 would be on the right of 2/10, not the left.
d. Same logic as parts b and c. 7 is greater than 4, so 4/10 should be on the left of 7/10 not right.

that's 2kg because 22*.75 is 17 the difference is -5 each time. 17- another 5 is 12 or 2/4 the original amount. you keep going and at the end you are left with 2kg
