Step-by-step explanation:

Using the z-distribution, it is found that since the p-value is greater than 0.05, the proportion does not differ from 23%.

At the null hypotheses, it is tested if the proportion is of 23%, that is:

[tex]H_0: p = 0.23[/tex]

At the alternative hypotheses, it is tested if the proportion differs from 23%, hence:

[tex]H_1: p \neq 0.23[/tex]

The test statistic is given by:

[tex]z = \frac{\overline{p} - p}{\sqrt{\frac{p(1-p)}{n}}}[/tex]

In which:

The parameters are given as follows:

[tex]p = 0.23, n = 200, \overline{p} = \frac{51}{200} = 0.255[/tex]

The value of the test statistic is:

[tex]z = \frac{\overline{p} - p}{\sqrt{\frac{p(1-p)}{n}}}[/tex]

[tex]z = \frac{0.255 - 0.23}{\sqrt{\frac{0.23(0.77)}{200}}}[/tex]

z = 0.84.

Using a calculator and considering a two-tailed test, as we are testing if the proportion is different of a value, with z = 0.84, the p-value is of 0.4.

Since the p-value is greater than 0.05, the proportion does not differ from 23%.

Answer:

The inverse is 5x-6

Step-by-step explanation:

To find the inverse of a function

y = ( x+6) /5

Exchange x and y

x = ( y+6)/5

Solve for y

Multiply each side by 5

5x = (y+6)/5 *5

5x = y+6

Subtract 6  from each side

5x-6 = y+6-6

5x-6 =y

The inverse is 5x-6

Step-by-step explanation:

[tex]f(x) = \frac{x + 6}{5} [/tex]

[tex] \: [/tex]

[tex]y = \frac{x + 6}{5} [/tex]

[tex] \frac{y + 6}{5} = x[/tex]

[tex]y + 6 = 5\times x[/tex]

[tex]y + 6 = 5x[/tex]

[tex]y = 5x - 6[/tex]

[tex] {f}^{ - 1} (x) = 5x - 6[/tex]

The slope intercept equation is 3y+ 2x = -4.5,

The equation of a straight line in the form y = mx + b where m is the slope of the line and b is its y-intercept.

let the two points from the graph is (4, -4) and (-2, 0)

then

m= 4/ -6= -2/3

and the intercept is 1.6 as the line intersects the y- axis.

So, the slope intercept is

y= -2/3x - 1.6

3y= -2x - 4.5

3y+ 2x = -4.5

Answer:

x = 65 , y = 64

Step-by-step explanation:

y - 16 and 2y + 4 are same- side interior angles and sum to 180° , that is

y - 16 + 2y + 4 = 180

3y - 12 = 180 ( add 12 to both sides )

3y = 192 ( divide both sides by 3 )

y = 64

then

2y + 4 = 2(64) + 4 = 128 + 4 = 132

the exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.

2y + 4 is an exterior angle of the triangle , then

x + 67 = 132 ( subtract 67 from both sides )

x = 65

Probability helps us to know the chances of an event occurring. The number of times Tamika should expect the spinner to land on green or yellow is 60.

Probability helps us to know the chances of an event occurring.

[tex]\rm Probability=\dfrac{Desired\ Outcomes}{Total\ Number\ of\ outcomes\ possible}[/tex]

Total number of sections on the spinner = 5

Number of sections with green or yellow sections = 2

Number of trials = 150

Now, the number of times Tamika should expect the spinner to land on green or yellow is,

Expected Number of lands on green or yellow = 150 × (2/5) = 60

Hence, the number of times Tamika should expect the spinner to land on green or yellow is 60.

ABC is a right-angled triangle.

b=16 cm

∠C=38°

Calculate the length of AB. Give your answer correct to 2 decimal places.

The picture is also attached below.

The length of the side AB is 9.85 cm.

From the triangle, it is given that

b= AC=16 cm

∠C=38°

Given that ΔABC is a right-angled triangle.

where ∠B=90°

So, here we can apply the  SOH CAH TOA identity

As we know the value of sinθ is the ratio of the opposite side and the hypotenuse of the angle θ.

So, sinθ = opposite side/ hypotenuse

In triangle ΔABC

⇒ sin 38°= AB/AC

⇒ sin 38°= AB/16

⇒ AB= 16 sin 38°

⇒ AB= 9.85 cm

Therefore the length of the side AB is 9.85 cm.

If any of its inner angles is 90 degrees, the triangle is said to be right-angled. Another term for this triangle is the right triangle or 90-degree triangle.

From the given triangle, it is observed that one of the angles is 90°, showing the given triangle is a right-angle triangle.

From the Δ ABC we found;

tan 45° = AB/BC

1=AB/BC

AB=BC

sin 45° = AB/AC

(1/√2)=AB/AC

AC = √2 AB

From the graph, it is observed that

AB=BC =3 units

AC=  √2 AB

AC = 3√2 units

Hence, the measurement of sides AB, BC, and AC will be 3 units,3 units, and 3√2 units respectively.

Answer:

1/18

Step-by-step explanation:

So to find the probability of two independent events, you simply multiply the two probabilities. So the probability of rolling any individual number is 1/6 because there's 6 possibilities, and there are no duplicate numbers. So the probability of rolling a 2 the first time is 1/6. The probability of rolling a number greater than 4 has a probability of 2/6, since the numbers 5 and 6 are both greater than 4. This can be further simplified to 1/3. Multiplying these two probabilities gives you 1/18

Perimeter of the shape = 27.15 units.

Perimeter = = 1/2(2π(5/2)) + [√(9² + 5²)] + 9 = 7.85 + 10.3 + 9 = 27.15 units.

Area = 1/2(area of circle) + area of triangle = 1/2(πr²) + 1/2(bh)

The transformations rule for changing DEF into D"E"F is

(b) T-5,0-RO. 90° (x,y)

To transform a shape is to alter its dimensions and relative placement.

To convert from DEF to D"E"F, use this rule:

(b) T-5,00 RO, 90°(x, y)

From the complete question,

When DEF is spun 90 degrees counterclockwise, it becomes GH.

Then, 5 units were subtracted from the right and translated to the left.

Assume a rotation of 90 degrees counterclockwise, and write it as:

RO, 90°(x,y)

As a symbol, the leftward translation of 5 units looks like this:

T-5,0(x,y)

When both transformations are combined, we have:

T-5,0 R0.90° (x. y)
