Answer:

Step-by-step explanation:
The diagram shows right triangle with hypotenuse of 15 units and angle of 30°. This angle is opposite to the leg with length of x units.
In the right triangle, the leg opposite to the 30° angle is half of the hypotenuse, so

She has 2 dimes and 4 nickels.
Knowing dimes equal 10 cents, if you have 1 dime and 3 nickels, you’d have 20 cents, 2 dimes and 4 nickels you’d have 40 cents. You have to have two more nickels than dimes.
Answer:
3x + 6y
x = sliders
y = onion rings
Step-by-step explanation:
2:1 ratio of onion rings to sliders, add them 200+70+70 = 340,
then 1020/340 = 3, then input into an equation remembering the ratio of onion rings to sliders
Answer:
There is enough evidence to support the claim that the true proportion of monitors with dead pixels is greater than 5%.
Step-by-step explanation:
We are given the following in the question:
Sample size, n = 300
p = 5% = 0.05
Alpha, α = 0.05
Number of dead pixels , x = 24
First, we design the null and the alternate hypothesis
This is a one-tailed(right) test.
Formula:
Putting the values, we get,
Now, we calculate the p-value from excel.
P-value = 0.00856
Since the p-value is smaller than the significance level, we fail to accept the null hypothesis and reject it. We accept the alternate hypothesis.
Conclusion:
Thus, there is enough evidence to support the claim that the true proportion of monitors with dead pixels is greater than 5%.
