Step-by-step explanation:
∠FZE and ∠BZC are vertical angles, so are congruent. The angle sum theorem tells us ...
∠BZC +∠CZD = ∠BZD
(2x+5) +x = 107
3x = 102
x = 34
The measure of ∠CZD is 34°.

A store is having a sale on almonds and jelly beans. For 2 kilograms of almonds and 3 kilograms of jelly beans, the total cost is $11. For 6 kllograms of almonds and 5 kilograms of jelly beans, the total cost is $23. Find the cost for each kilogram of almonds and each kilogram of jelly beans.
Find cost for each kilogram of almonds :?
Ans find the cost for each kilogram of jelly beans :?
Answers
Answer:
The cost of each kg of almonds is $1.75
The cost of each kg of jelly beans is $2.5
Step-by-step explanation:
We will use the system of linear equations to solve the question
Assume that the cost of 1 kg of almonds is $x, and the cost of 1 kg of jelly beans is $y
∵ For 2 kilograms of almonds and 3 kilograms of jelly beans,
the total cost is $11
→ Multiply 2 by x and 3 by y, then equate their sum by 11
∴ 2x + 3y = 11 ⇒ (1)
∵ For 6 kilograms of almonds and 5 kilograms of jelly beans, the
total cost is $23
→ Multiply 6 by x and 5 by y, then equate their sum by 23
∴ 6x + 5y = 23 ⇒ (2)
Now we need to solve this system of equations to find the values of x and y
→ Multiply equation (1) by -3 to make the coefficient of x in it equals
the coefficient of x in equation (2) in values and differences in signs
∵ -3(2x) + -3(3y) = -3(11)
∴ -6x + -9y = -33 ⇒ (3)
→ Add equations (2) and (3) to eliminate x
∵ (6x + - 6x) + (5y - 9y) = (23 + -33)
∴ -4y = -10
→ Divide both side by -4 to find the value of y
∵ [tex]\frac{-4y}{-4}=\frac{-10}{-4}[/tex]
∴ y = 2.5
→ Substitute the value of y in equation (1) to find x
∵ 2x + 3(2.5) = 11
∴ 2x + 7.5 = 11
→ Subtract 7.5 from both sides
∵ 2x + 7.5 - 7.5 = 11 - 7.5
∴ 2x = 3.5
→ Divide both sides by 2 to find the value of x
∵ [tex]\frac{2x}{2}=\frac{3.5}{2}[/tex]
∴ x = 1.75
∵ x represents the cost of 1 kg of almonds
∴ The cost of each kg of almonds is $1.75
∵ y represents the cost of 1 kg of jelly beans
∴ The cost of each kg of jelly beans is $2.5

A researcher wants to test to see if husbands are significantly older than their wives. To do this, he collects the ages of husbands and pairs them with the ages of their respective wives for a random set of married couples. Suppose that data were collected for a random sample of 12 couples, where each difference is calculated by subtracting the age of the wife from the age of the husband. Assume that the ages are normally distributed. The test statistic is t≈1.434, α=0.05, the corresponding rejection region is t>1.796, the null hypothesis is H0:μd=0, and the alternative hypothesis is Ha:μd>0. Which of the following statements are accurate for this hypothesis test in order to evaluate the claim that the true mean difference between the age of the husband and the age of the wife is greater than zero?
Answers
Complete Question
The complete is shown on the first uploaded image
Answer:
The correct option are option 2 and option 4
Step-by-step explanation:
From the question we are told that
The sample size is n = 12
The test statistics is [tex]t \approx 1.434[/tex]
The level of significance is [tex]\alpha = 0.05[/tex]
The rejection region is t>1.796
The null hypothesis [tex]H_o: \mu_d=0[/tex]
The alternative hypothesis is [tex]H_a : \mu_d >0[/tex]
From the given values we see that t < 1.796(i.e 1.434 < 1.796 ) which implies that t is not within the rejection region
Hence we fail to reject the null hypothesis
The conclusion is that there is insufficient evidence to suggest that that the husbands are significantly older than the wife.

Find m\angle Am∠Am, angle, A. Note that m\angle Am∠Am, angle, A is acute. Round to the nearest degree. \Large{^\circ} ∘ degrees
Answers
Answer:
The answer is that the measure of ∠α is ≈ 20° when rounded to the nearest °
Step-by-step explanation:
To find the measure of ∠α you need to use the reciprocal of the formula for the law of sine which says that a/Sinα = b/Sinβ = c/Sin C. The reciprocal of this gives the new equation that states Sinα/a = Sinβ/b = Sin C/c, and this will help you to find the measure of the missing angle in °'s.
In the triangle line segment BC = 5units is opposite to point A & ∠α. Line segment AC = 7units is opposite of point and ∠β which is = 28°. And finally, the hypotenuse length and the values of point C & ∠C are unknown, so they aren't important to solving the problem. Knowing all this you can plug in all the known values into the new formula, and start working on figuring things out.
To find the measure ∠α, you first write down everything, putting things into their proper places, so since you're solving for sinα you want the equation to look like this:
sinα/5 = sin28°/7
Then for the second step, you want to isolate the sinα. (To get it by itself × both left and righthand sides by 5 to begin simplifying).
This leaves you with :
sinα = sin28°÷7 · (5) [And allows you to now solve for the right side of the equation, bringing us to our third step which is to once again simplify. So what you want to do is whip out your calculator and set it to degree mode, so you can find the of sin28° which is = 0.46947156278. Then ÷ that by 7, which will get you a number = 0.06706736611. Finally, take 0.06706736611 × 5, and you will get the value = 0.33533683056, as your final answer in the third step]
Your equation should now look something like this :
sinα = 0.06706736611 × 5 or 0.33533683056
Moving onto the fourth step, you need to use the inverse of the trig function of sin to get your absolute value. (remember the inverse of sine or acrsin = sin^-1) Here you will need to multiply sin^-1 by 0.33533683056.
And also by now, you'll want to stop writing the equation as sinα = sin^-1 ×
0.33533683056, otherwise you won't get an answer, instead, you'll need to write:
α = sin^-1 × 0.33533683056
So once you do that for the fifth and final step, you'll need to simplify the equation on the righthand side one last time, and you should get the answer of α = 19.5930217327°. Which when rounded to the nearest ° is ≈ 20°.

When it fails, its failure will be a type 1 failure with probability 0.7 and a type 2 failure with probability 0.3. Type 1 failures take an exponential amount of time with mean 1 hour to repair. Type 2 failures take an exponential amount of time with mean 1.25 hours. The status of the machine can be monitored as a continuous-time Markov chain with states 0 (= working), 1 (= repairing a type 1 failure), 2 (= repairing a type 2 failure).
