In The Coordinate Plane, Which Of The Following Functions Dilates By A Factor Of 3about The Point (9,
Answer 2

The points after dilation is (27, 18).

What is Dilation?

Resizing an item uses a transition called dilation. Dilation is used to enlarge or contract the items. The result of this transformation is an image with the same shape as the original.

Enlargements are dilations that result in a larger image. Reduction is the name for a dilatation that shrinks the image. The initial figure is stretched or contracted by a dilatation.

Given:

Scale Factor= 3

Points (9, 6).

If the coordinates is dilated by factor 3.

Then, (9, 6).

= (9(3), 6(3)).

= (27, 18)

Hence, the points after dilation is (27, 18).

A random sample of 450 vacationers in a huge luxury resort showed that 150 were business executives. We want to create a 95% confidence interval for the proportions of vacationers who are business executives.

a) What is the value at the centre of the 95% confidence interval? Write the symbol and value.

Answers

Answer:

p(s) = 0,33

Step-by-step explanation:

n = 450

p₀ = 150/450       p₀ = 0,33      then    q₀  = 0,67

n*p₀ = 0,33*450  =  150

n*q₀  = 0,67*450 = 301

n*p₀  and n*q₀   more than 10, we can approximate  the binomial to a Normal Distribution Distribution

a) p - p₀  = z(c) * √ (p₀q₀)/n

z(c) =  ??

CI   95 %    then α = 5 %    α = 0,05      α/2 = 0,025

z(c) = 1,96

p  =  p₀  ±  z(c) * √ (p₀q₀)/n

p  = 0,33 ± 1,96 * 0,022

p =  (  0,33 - 0,04 ;  0,33 +  0,04

p = ( 0,29  ; 0,37 )

The value of the center of the confidence Interval is 0,33

p(s) = 0,33

4. x = 17

2. x = 77; y = 103

Step-by-step explanation:

4. The acute angles of a right triangle are complementary.

2x + 3x + 5 = 90

5x = 85

x = 17

2.

Same side interior angles are supplementary.

x + 103 = 180

x = 77

y and 103-deg angle are vertical angles, so they are congruent.

y = 103

Using traditional methods, it takes 94 hours to receive a basic driving license. A new license training method using Computer Aided Instruction (CAI) has been proposed. A researcher used the technique with 40 students and observed that they had a mean of 95 hours. Assume the standard deviation is known to be 3. A level of significance of 0.02 will be used to determine if the technique performs differently than the traditional method. Find the value of the test statistic. Round your answer to 2 decimal places. Enter the value of the test statistic

Answers

Answer: the value of the test statistic is 2.11

Step-by-step explanation:

Given that;

sample mean x" = 95

standard deviation σ = 3

sample size n = 40

Null hypothesis H₀ : μ = 94

Alternative hypothesis H₁ : μ ≠ 94

Level of significance ∝ = 0.02

Test statistic value

z = (x" - μ) / ( σ/√n)

we substitute

z = (95 - 94) / ( 3/√40)

z = 1 / 0.4743

z = 2.11

Therefore, the value of the test statistic is 2.11
