Answer:

The correct interpretation of the value 0.45 is that there is a 4.5% chance that the true proportion of blue beads in the container is 0.30.

This means that there is a 4.5% probability that the sample proportion of blue beads would be 0.20 or less by chance alone. This means that there is not enough evidence to reject the null hypothesis (H0: p=0.30) and suggest that the true proportion of blue beads in the container is less than 0.30.

The measure of angle A is 63°, the measure of side b is 22.34 feet and the measure of side a is 37.57 feet.

From the given triangle ABC,

∠A+∠B+∠C=180° (Angle sum property of a triangle)

∠A+32°+85°=180°

∠A+117°=180°

∠A=180°-117°

∠A=63°

We know that, the formula for sine rule is sinA/a=sinB/b=sinC/c

Here, sin63°/a = sin32°/b = sin85°/42

sin63°/a = sin32°/b = 0.9961/42

sin32°/b = 0.9961/42 and sin63°/a = 0.9961/42

0.5299/b = 0.9961/42

0.9961b=22.2558

b=22.2558/0.9961

b=22.34 feet

sin63°/a = 0.9961/42

0.8910/a = 0.9961/42

0.9961a=37.422

a=37.422/0.9961

a=37.57 feet

Therefore, the measure of angle A is 63°, the measure of side b is 22.34 feet and the measure of side a is 37.57 feet.

To use the discriminant to determine the number and type of solutions for a quadratic equation, we simply need to calculate b² - 4ac and examine the value.

The discriminant of a quadratic equation is a value that can be used to determine the nature and number of solutions for the equation. The discriminant is found by calculating b² - 4ac, where a, b, and c are the coefficients of the quadratic equation ax² + bx + c = 0.

If the discriminant is positive, then the equation has two real solutions. If the discriminant is zero, then the equation has one real solution (a double root). If the discriminant is negative, then the equation has no real solutions but two complex solutions.

If it is positive, there are two real solutions; if it is zero, there is one real solution; if it is negative, there are no real solutions.

For example, consider the quadratic equation 2x² + 4x + 3 = 0. The coefficients are a = 2, b = 4, and c = 3. The discriminant is b² - 4ac = 4² - 4(2)(3) = 16 - 24 = -8. Since the discriminant is negative, the equation has no real solutions but two complex solutions.

isosceles right triangle

Step-by-step explanation:

(1, 1) and (1, 4) are 3 units apart

(1, 1) and (4, 1) are 3 units apart

(1, 4) and (4, 1) are 3√2 units apart

So we have an isosceles right triangle.

Answer:

Option D, isosceles right triangle

Step-by-step explanation:

Step 1:  Use logic

Looking at the given points, we know that there are 3 points which means that this is going to be a triangle.  This removes options B and C from the mix and we are only left with A and D.  

Isosceles right triangle means that the two legs next to the right angle are equal to each other.  Scalene right triangle means that the two legs next to the right angle are different from each other.  We can see that the distance between (1, 1) and (1, 4) is 3 units and the distance between (1, 1) and (4, 1) is also 3 units.  Therefore this is an isosceles right triangle.

Answer:  Option D, isosceles right triangle

Answer:759

Step-by-step explanation:

Answer:

a = 43°

b = 90°

c = 43°

Step-by-step explanation:

Since, angle inscribed by a semicircle measure 90°.

Therefore, measure of angle 'b' = 90°

Since, measure of the intercepted arc in a semicircle = 180°

Therefore, c° + 137° = 180°

c = 180 - 137

c = 43°

Since, measure of the intercepted arc is double of the inscribed angle.

Therefore, 2(a) = 130°

a = 65°

Step 1 is correct. She subtracted 7 from both sides. That's why the 12 becomes 12-7 = 5.

Her step 2 is not correct because she should have multiplied both sides by 5. The correct step 2 should look like 2n = 25. Then after this, she should divide both sides by 2 to get n = 25/2 = 12.5

Answer:

12.5

Step-by-step explanation:

The coordinates of the vertex of the parabola are (3, -7). The focus of the parabola is located at (3, -3). The equation of the directrix is y = -11.

The given equation of the parabola is in the form (x - h)^2 = 4p(y - k), where (h, k) represents the vertex and p represents the distance between the vertex and the focus/directrix.

Comparing the given equation with the standard form, we can see that the vertex is at (3, -7).

The coefficient 4p in this case is 16, so p = 4. Since the parabola opens upward, the focus will be p units above the vertex. Therefore, the focus is located at (3, -7 + 4) = (3, -3).

To find the directrix, we need to consider the distance p below the vertex. Since the parabola opens upward, the directrix will be p units below the vertex. Hence, the equation of the directrix is y = -7 - 4 = -11.

In summary, the coordinates of the vertex are (3, -7), the focus is located at (3, -3), and the equation of the directrix is y = -11.

Based on the supply graph and demand graph shown above, the price at the point of equilibrium is $ 30.

Demand refers to quantity of a commodity that the consumers are willing to, able to purchase at a given price during a given period of time. Supply refers to quantity of a commodity that the producers are willing to, able to offer for sale at a given price during a given period of time.

Demand curve slopes downward due to inverse relationship between price and quantity demanded whereas supply curve slopes upward due to direct relationship between quantity supplied and price. When both demand and supply curve intersect with each other balance is achieved. Intersection point between demand and supply curve is known as equilibrium.

At this point when prices are equal is known as equilibrium price and when quantiy demanded or supplied are equal it is known as equilibrium quantity. When we combine the given graph. Equilibrium is achieved at a point when price is equal to $ 30 and quantity is equal to 20 units.

Answer:

Increase the sample size.

Step-by-step explanation:

Increasing the sample size is the best way to reduce the likelihood of a type II error.

The type II error occurs when a hypothesis test accepts a false null hypothesis. That is, it fails to reject the null hypothesis that is false.

In such a situation, to increase the power of the test, you have to increase the sample size used in the test. The sampling size has the ability to detect the differences in a hypothesis test.

We have a bigger chance of capturing the difference if the sample size is larger, and it also increases the power of the test.

What is a line segment ?

A line segment in geometry is bounded by two separate points on a line. Another way to describe a line segment is as a piece of the line that joins two points. A line segment has two fixed or distinct endpoints while a line has no endpoints and can stretch in both directions indefinitely.

For sapling 1 = No distance is covered.

For sapling 2, distance covered = 10 m

Return distance=10 m

For sapling 3, distance covered =20 m

Return distance=20 m and so on

Thus the distances covered for saplings can be represented as : 0,2(10), 2(20),...i.e. 0,20, 40,...

Therefore total distance covered by Jeremy for planting 12 saplings and coming back to original position = S 12

Total distance covered = 122 [2(0) + (12 − 1) 20 ]

Total distance covered = 6 (11)(20) = 1320 m

Answer:

Step-by-step explanation:

You split it up into two 3-D triangles.

One of them has a volume of ((6*(5+5))/2)*8 = (60/2)*8=240

For the other one, you are missing a side on the 2-D face, so in order to apply pythagorean's theorem you need to split it into two more triangles. You know that 13^2=5^2+x^2    169-25=x^2         144=x^2  x=12

now that you know the missing side of the triangle you can recombine them. The volume of the remaining 3-D triangle is (((5+5)*12)/2)*8 = 60*8=480

480+240=720 meters cubed

Answer:

57⁰

Step-by-step explanation:

A triangle measures 180⁰, so to find the answer to these questions you just have to add the degrees you know

after you take 180⁰ and subtract the degrees you know your triangle has

180⁰-123⁰= 57⁰

Answer:

57°

Step-by-step explanation:

so triangle angles all add up to 180 so its a matter of subtraction

\(92 + 31 + x = 180\)

x is the 3rd angle we need to find

\(92 + 31 + x = 180\\\\92 + 31 = 123\\\\180 - 123 = 57\\\)

so the missing 3rd angle is 57°
