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)

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.

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.

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°

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.

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.

Answer:

I assume it would be 15 loves of banana bread.

Step-by-step explanation:

if you do 8 loves of pumpkin bread, you get $24 profit.

If you do 15 loves of banana bread, you get $37.50 in profit.

To maximize the profit of $38 , baker should make 12 loaves of banana bread and 2 loaves of pumpkin bread.

" Linear inequalities are defined as algebraic expression which are related with the sign of inequality."

According to the question,

'x' represents the number of loaves of banana bread

'y' represents the number of loaves of pumpkin bread

As per the given condition,

Total profit  on making bread [tex]'P' = 2.50x + 4.00y[/tex]     ____(1)

Linear inequalities are

[tex]2x + 3y\leq 30\\\\x+ 2y \leq 16[/tex]

By solving linear inequalities we get,  

[tex]x= 12\\ \\y =2[/tex]

As shown in the diagram drawn , point of intersection  is (12,2) for the given inequality.

Substitute the value of 'x' and 'y' in (1) to get the maximize profit ,

Maximize profit ' P' [tex]= 2.50(12) + 4 (2)[/tex]

                          [tex]= 30 + 8\\= \$38[/tex]

Hence, to maximize the profit of $38 , baker should make 12 loaves of banana bread and 2 loaves of pumpkin bread.
