The areas of the trapezoid is 50 units².

The trapezoid PQRS have bases 10 and 12 units respectively. The height of the trapezoid is unknown. Let's find the area of the trapezoid as follows:

area of trapezoid = 1 / 2 (a + b)h

where

Therefore,

a = 10 units

b = 15 units

Using Pythagoras's theorem,

5² - 3² = h²

h = √25 - 9

h = √16

h = 4 units

area of trapezoid = 1 / 2 (10 + 15)4

area of trapezoid = 1 / 2 × 25 × 4

area of trapezoid = 100 / 2

area of trapezoid = 50 units²

Using the z-distribution, as we are working with a proportion, it is found that there is evidence that the phrasing may have influenced responses.

At the null hypothesis, it is tested if there is no difference between the proportions, that is:

\(H_0: p_1 - p_2 = 0\)

At the alternative hypothesis, it is tested if there is difference, that is:

\(H_1: p_1 - p_2 \neq 0\)

For each sample, we have that:

\(p_1 = \frac{463}{615} = 0.7528, s_1 = \sqrt{\frac{0.7528(0.2472)}{615}} = 0.0174\)

\(p_2 = \frac{403}{585} = 0.6889, s_2 = \sqrt{\frac{0.6889(0.3111)}{585}} = 0.0191\)

For the distribution of differences, we have that:

\(\overline{p} = p_1 - p_2 = 0.7528 - 0.6889 = 0.0639\)

\(s = \sqrt{s_1^2 + s_2^2} = \sqrt{0.0174^2 + 0.0191^2} = 0.0258\)

It is given by:

\(z = \frac{\overline{p} - \mu}{s}\)

In which \(\mu = 0\) is the value tested at the null hypothesis.

Hence:

\(z = \frac{\overline{p} - \mu}{s}\)

\(z = \frac{0.0639 - 0}{0.0258}\)

\(z = 2.47\)

Considering a two-tailed test, as we are testing if the proportion is different of a value, and a significance level of 0.05, the critical value is \(|z^{\ast}| = 1.96\).

Since the absolute value of the test statistic is greater than the critical value, it is found that there is evidence that the phrasing may have influenced responses.

Step-by-step explanation:

The expression ⁵√p¹¹ is equivalent to the given expression. The correct answer would be an option (C).

Exponential expressions, as the name indicates, involve exponents. We already know that the exponent of a number (base) specifies how many times the number (base) has been multiplied.

The exponential expression is given in the question, as follows:

\(p^\frac{11}{5}\)

We have to determine the equivalent expression to the given expression.

As per option (C), we have

⇒ ⁵√p¹¹

The above expression also can be written as:

The principal amount was £1260, and the annual interest rate is 5.5%.

Given that, Olivia gets £1606.50 and £1675.80 after 5 years and 6 years of investment in simple interest respectively.

SI = principal × rate × time / 100

So,

P + 5pr = £1606.50

P = £1606.50 - 5pr............(i)

P + 6pr = £1675.80

P = £1675.80 - 6pr.........(ii)

Therefore,

£1606.50 - 5pr = £1675.80 - 6pr

Pr = 69.3

Put the value of pr in eq(i)

P + 5(69.3) = 1606.50

P = 1606.5 - 346.5

P = 1260

Now,

(1260)r = 69.3

r = 0.055

In Geometry, dilation can be defined as a type of transformation which typically changes the size of a geometric object, but not its shape. This ultimately implies that, the size of the geometric object would be increased or decreased based on the scale factor used.

Next, we would have to dilate the coordinates of the preimage by using a scale factor of 3/5 centered at the origin as follows:

Ordered pair A (-4, 6) → Ordered pair A' (-4 × 3/5, 6 × 3/5) = Ordered pair A' (-2.4, 3.6).

Ordered pair B (-2, 2) → Ordered pair B' (-2 × 3/5, 2 × 3/5) = Ordered pair B' (-1.2, 1.2).

Ordered pair C (4, -2) → Ordered pair C' (4 × 3/5, -2 × 3/5) = Ordered pair C' (2.4, -1.2).

Step-by-step explanation:

Answer:

Angle x is 64 degrees. Angle y is 128.

Step-by-step explanation:

To find angle x:

In an isosceles triangle, the base angles are always congruent (equal). Since we know that one of the base angles is 64, and x is also a base angle, x is 64 degrees as well.

To find angle y:

Again, in an isosceles triangle, the base angles are always congruent. Since we know that one of the base angles is 26, we know that the other base angle is also 26. Then, to find the last angle (y), you use the triangle angle sum theorem which states that all angles in a triangle add up to 180. To figure out angle y, you do 180-26-26 to get 128. So angle y is 128 degrees.

Unit analysis is a tool that we can use to convert units. It involves multiplying the original number by a fraction to cancel out units.

Answer: its D because Jews (Hebrew: יְהוּדִים, ISO 259-2: Yehudim, Israeli pronunciation: [jehuˈdim]) or Jewish people are an ethnoreligious group,[10] nation or ethnos[11][12] originating from the ancient Israelites[13][14][15] and Hebrews[16][17][18] of historical Israel and Judah. Jewish ethnicity, nationhood, and religion are strongly interrelated,[19][20] as Judaism is the ethnic religion of the Jewish people, although its observance varies from strict to none.[21][22]

Jews originated as an ethnic and religious group in the Middle East during the second millennium BCE,[9] in a part of the Levant known as the Land of Israel.[23] The Merneptah Stele of ancient Egypt appears to confirm the existence of a people of Israel somewhere in Canaan as far back as the 13th century BCE (Late Bronze Age).[24][25] The Israelites, as an outgrowth of the Canaanite population,[26] consolidated their hold in the region with the emergence of the kingdoms of Israel and Judah. Some consider that these Canaan-sedentary Israelites melded with incoming nomadic groups known as the "Hebrews".[27] The experience of life in the Jewish diaspora, from the Babylonian captivity and exile (though few sources mention this period in detail[28]) to the Roman occupation and exile, and the historical relations between Jews and their homeland in the Levant thereafter became a major feature of Jewish history, identity, culture, and memory.[29]

In the following millennia, Jewish diaspora communities coalesced into three major ethnic subdivisions according to where their ancestors settled: the Ashkenazim (Central and Eastern Europe), the Sephardim (initially in the Iberian Peninsula), and the Mizrahim (Middle East and North Africa).[30][31] Prior to World War II, the global Jewish population reached a peak of 16.7 million,[32] representing around 0.7 percent of the world population at that time. During World War II, approximately 6 million Jews throughout Europe were systematically murdered by Nazi Germany during the Holocaust.[33][34] Since then, the population has slowly risen again, and as of 2018, was estimated to be at 14.6–17.8 million by the Berman Jewish DataBank,[1] comprising less than 0.2 percent of the total world population.[35][note 1] The modern State of Israel is the only country where Jews form a majority of the population.

=====================================================

Explanation:

Plug n = 2 into the 2nd equation. We'll involve f(1) = 2.

f(n)=f(n-1)^2-3

f(2) = [ f(2-1) ]^2-3

f(2) = [ f(1) ]^2 - 3

f(2) = (2)^2 - 3 .... replace f(1) with 2; since f(1) = 2

f(2) = 4 - 3

f(2) = 1

-------------

For the last group of steps, we plug in n = 3.

We'll involve f(2) = 1.

f(n) = [ f(n-1) ]^2-3

f(3) = [ f(3-1) ]^2 - 3

f(3) = [ f(2) ]^2 - 3

f(3) = (1)^2 - 3

f(3) = 1 - 3

f(3) = -2 which is the final answer

  B)  15/17

Step-by-step explanation:

You want the sine of acute angle A in the right triangle shown.

The sine of the angle is the ratio ...

  Sin = Opposite/Hypotenuse

We can go to the trouble to figure the hypotenuse, or we can choose the only suitable answer from the list provided. (It is the one marked already.)

The leg lengths of the triangle shown are 8 and 15, with leg 15 being opposite angle A. This is the first clue that the ratio will have 15 in the numerator. Only answer choice B matches.

The value of the sine function is never greater than 1, eliminating answer choices A, C, and E, leaving choices B and D.

Since the side opposite angle A is the longest of the two legs, we know that angle A is more than 45°, and its sine is more than √2/2. That means choice D can be eliminated, since it is less than 1/2.

The sine of angle A is 15/17.
