A full tin of paint has a mass of 22 kg.When the same tin is 3/4 filled with paint,it has a mass of 17 kg.What is the mass of the empty tin

Answers

Answer: 2 kg

Step-by-step explanation:

3/4(22-x)=17-x

66/4-3/4x=34/2-x

33/2-3/4x=34/2-x

1/4x=1/2

x=2

Answer:

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

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​

Answers

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.

Express 15 3/5 as a fraction in simplest form

Answers

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

The answer is 78/5..

The answers are x>5, x>-1/2, x>7

If any of the terms is 0 it makes the whole equation 0. Because we know anything multiplied by 0 is 0.

0 (B) (C) = 0
(A) 0 (C) = 0
(A) (B) (0) = 0

So we can just set up each of the terms in separate equals in regards to being greater than 0.

on a number line, where would 4/10 be located? choose all answers that make a true statement.

Answers

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.

1. In the adjoining figure, p||q .Find the unknown angles.

Answers

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)

The first side of a triangle measures 4 in. less than the second side, the third side is 3 in. more than the first side, and the perimeter is 15 in. How long is the third side?



If s represents the length of the second side, which of the following represents the length of the third side?

s - 4
s + 3
s - 1

Answers

Less would be minus and more is plus so the first side is 4 less than the second, or s - 4, and the third side is 3 more than the first, or
3 + s - 4.
3-4 + s = -1 + s or s - 1

So the answer is the third option, s - 1.

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.
