HELP!!!!!!!!!!!!!!!!!!!!!!!!

The question is incomplete as the total number I crosswords required for completion isn't given :

Hypothetically, if the total Number of cross words is taken as x ;

Answer:

2 /x

Step-by-step explanation:

The number of crosswords John did = 1 + 1 = 2

Total number of cross words = x

Fraction of crosswords John did :

2 / total number of crosswords

2 / x

Kindly substitute the actual number of crosswords for X to obtain exact answer.

Answer:

The summer in Maine is either not hot or it is not sunny.

Step-by-step explanation:

Suppose we have two events, A and B.

The negation of A and B is not A or not B.

The summer in Maine is hot and sunny.

Negation of hot an sunny is not hot or not sunny, so the correct option is:

The summer in Maine is either not hot or it is not sunny.

Below is the solution to the given points:

Step-by-step explanation:

For point a:

There have 30 overviews paired here and we'd like to analyze the mean studying time in the middle and final periods. It will employ a paired t-test. The difference (d) = mid - final

Hypotheses:

[tex]H_o: \mu_d \geq 0\\\\H_a: \mu_d < 0[/tex]

For point b:

More than three variables should be examined here because ANOVA is employed in one method.

For point c:

This one Z test is used since we have the standard difference in population.

Hypotheses:

[tex]H_o:\mu = 45\\\\ H_a:\mu\neq 45[/tex]

For point d:

Since not knowing the sample standard deviation, we will use an individual sample t-test.

Hypotheses:

[tex]H_o: \mu = 45\\\\ H_a: \mu \neq 45[/tex]

Answer:

The null hypothesis is [tex]H_0: \mu = 23.2[/tex]

The alternate hypothesis is [tex]H_a: \mu \neq 23.2[/tex]

Step-by-step explanation:

Null hypothesis:

The product is supposed to contain 23.2% potassium by weight, which means that at the null hypothesis, we test that this is the correct weight. So

[tex]H_0: \mu = 23.2[/tex]

Alternate hypothesis:

If the mean percentage is found to differ from 23.2, the manufacturing process will be recalibrated, which means that we test if the mean differs from 23.2, that is:

[tex]H_a: \mu \neq 23.2[/tex]

Answer:

Graph has the greater unit rate.

Step-by-step explanation:

From the graph attached,

Since, graph shows the proportional relationship,

y ∝ x

y = kx

Here, k = unit rate

If the line given in the graph passes through (0.2, 1.5)

Slope of this line will be,

k = [tex]\frac{1.5}{0.2}[/tex]

k = 7.5

Therefore, unit rate = 7.5

Equation of the line given in the question is,

[tex]y=\frac{11}{2}x+3[/tex]

Comparing this equation with the y-intercept form of the equation,

[tex]y=mx+b[/tex]

Slope of this line 'm' = [tex]\frac{11}{2}[/tex]

                                  = 5.5

Unit rate of the given equation = 5.5

Therefore, graph has the greater unit rate.

Answer:

[tex]18.83[/tex]

Step-by-step explanation:

For right triangles only, the tangent of an angle is equal to its opposite side divided by its adjacent side.

Therefore, we have the equation:

[tex]\tan 33^{\circ}=\frac{x}{29},\\x=29\tan 33^{\circ}\approx \boxed{18.83}[/tex]

Answer:

c = (d/a) - b

Step-by-step explanation:

a(c + b) = d

Divide both sides by a

c + b = d/a

subtract b from both sides

c = (d/a) - b

Answer:

  (1, 2)

Step-by-step explanation:

PR and QR are vertical and horizontal line segments, respectively. Then ΔQPR is a right triangle, and segment PQ is the hypotenuse. As such, segment PQ is also a diameter of the circumcircle, and its midpoint is the circumcenter.

  Circumcenter = (P+Q)/2 = ((4, 0) +(-2, 4))/2 = (2, 4)/2

  Circumcenter = (1, 2)

tan R = 9/19

............

The value of the trigonometric relation tan R = 9/19

Trigonometry is the study of the correlations between triangle angles and side lengths.

Sine, cosine, tangent, cosecant, sec, and cotone are the six trigonometric functions.

Let the angle be such that sin = opposed to the hypotenuse, cos = next to the hypotenuse, and tan = opposite to the adjacent. Cosec = 1/sin, sec = 1/cos, cot = 1/tan.

Given the data,

Let the triangle be denoted by the symbol RST.

Now, the triangle's other side ST equals nine units.

The triangle's base, RS, is equal to 19 units.

Moreover, the trigonometric relationship is tan R, where R has a value of

The result of substituting the values in the equation is

According to the trigonometric relationship, tan equals opposite or adjacent.

Tan R = ST / RS is the result of simplifying the equation.

tan R = 9 / 19

The trigonometric relationship is therefore tan R = 9/19.

Answer:

71°

Step-by-step explanation:

31-3x+19x-5=90

16x=90-26

16x=64

x=4

m<R=19x-5 = 19(4)-5 = 76-5 = 71

Answer:

x = 4

∠R = 71°

Step-by-step explanation:

COMPLEMENTARY ANGLES: TWO ANGLES WITH A SUM OF 90°.

[tex]31 - 3x + 19x - 5 = 90[/tex]

To make this problem easier to solve, we can combine like terms.

[tex]26 + 16x = 90.[/tex]

Now, we can proceed.

First, subtract 26 from 26 and 90.

[tex]26 - 26 = 0.[/tex] (cancels itself out).

[tex]90 - 26 = 64.\\[/tex]

Now, we are left with 16x = 64.

Lastly, we divide the number in front of the variable by the answer.

[tex]64/16 = 4[/tex]

Therefore, the value of x is 4.

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

Now that we have the value of x, we can use this value to replace the variable (x).

[tex]19x - 5[/tex]

[tex]19 * 4 - 5 = 71.[/tex]

Therefore, the value of ∠R is 71°.
