t + 23 > 1     subtract 23 from both sides

t + 23 - 23 > 1 - 23

t > -22

A figure is reflected over the y-axis. Which of the following are true? The pre-image and image are congruent. The y-coordinates
serg [7]
When a reflection occurs, the original graph and the reflected graph are mirror images of each other. So, when the graph is reflected about the y-axis, think of the y-axis as the mirror. When you fold the graph length-wise, you will see that both graphs would coincide. Thus, their y-coordinate would not change. It would only change to the opposite quadrant, thereby changing the signs of the x-coordinates. So, as a rule, during reflection, the coordinates (x,y) is changed to (-x,y).

Therefore, the answer is:<span>The x-coordinates' signs change..</span>

Find the circumference of the circle. Use pi = 3.14. Question 6 options: 3 m 18.84 m 6 m 28.26 m
Sladkaya [172]
Since you haven't provided the radius, I'll just use the symbol 'r' to refer to radius. You can substitute with the given radius in the equation.

Now, circumference of the circle is calculated using the following rule:
curcimference of circle = 2*pi*r
where:
r is the radius
pi is given as 3.14
Therefore:
circumference of circle = 2*3.14*r = 6.28 r units

Solve for x. Round to the nearest tenth, if necessary.
CaHeK987 [17]

Answer:

x ≈ 8.8

Step-by-step explanation:

Using the sine ratio in the right triangle

sin20° = \frac{opposite}{hypotenuse} = \frac{PQ}{OQ} = \frac{3}{x} ( multiply both sides by x )

x × sin20° = 3 ( divide both sides by sin20° )

x = \frac{3}{sin20} ≈ 8.8 ( to the nearest tenth )

Adults in Turkey have mean caloric intake of 3500 calories per day (Wikipedia) with a standard deviation of 500 calories. A samp
Alborosie

Answer:

A) Null hypothesis; H0: μ = 3500

Alternative hypothesis;Ha μ ≠ 3500

B) t = -1

C) the rejection region will be;

p-value < 0.05

D) Conclusion is that there is no sufficient evidence to support the claim that Ankara U. students average is not 3500 calories per day.

Step-by-step explanation:

We are given;

Population mean; μ = 3500

Population standard deviation; σ = 500

Sample mean; x¯ = 3400

Sample size; n = 25

We want to find enough evidence to conclude that Ankara U. students average is not 3500 calories per day.

Thus, the hypothesis is defined as;

A) Null hypothesis; H0: μ = 3500

Alternative hypothesis;Ha μ ≠ 3500

B) sample size is less than 30, thus we will use a t-test.

Formula for the test statistic is;

t = (x¯ - μ)/(σ/√n)

t = (3400 - 3500)/(500/√25)

t = -100/(500/5)

t = -1

C) since the sample is small, let's assume a significance level of 0.05.

Thus,the rejection region will be;

p-value < 0.05

D) from online p-value from t-score calculator attached using;

t = - 1; DF = 25 - 1 = 24; significance level = 0.05 and two tailed hypothesis, we have;

p-value ≈ 0.3273

This is greater than the significance value of 0.05.

Thus, we will fail to reject the null hypothesis and conclude that there is no sufficient evidence to support the claim that Ankara U. students average is not 3500 calories per day.
