answer:
y = 10 - x²
step-by-step explanation:
the y value is means the y value is equal to meaning the first part of our equation is y =
10 decreased means 10 minus so the next part of our equation is y = 10 -
the square of the x value means x squared so the last part of our equation is y = 10 - x²
Answer:
The measure of arc SQ is 95° ⇒ (1)
Step-by-step explanation:
- The measure of any circle is 360°
- The measure of the subtended arc to an inscribed angle is twice the measure of this angle
In the given circle
∵ S lies on the circumference of the circle
∴ ∠QSR is an inscribed angle
∵ ∠QSR is subtended by arc QR
→ By using the 2nd rule above
∴ m arc QR = 2 × m∠QSR
∵ m∠QSR = 95°
∴ m arc QR = 2 × 95
∴ m arc QR = 190°
→ By using the 1st rule above
∵ m of the circle = m arc QR + m arc SQ + m arc SR
∵ m arc SR = 75° and m arc QR = 190°
→ Substitute them in the equation above
∴ 360 = 190 + m arc SQ + 75
→ Add the like term in the right side
∴ 360 = 265 + m arc QS
→ Subtract 265 from both sides
∵ 360 - 265 = 265 - 265 + m arc SQ
∴ 95° = m arc SQ
∴ The measure of arc SQ is 95°
Answer:
Correct option is (c).
Step-by-step explanation:
The experiment is conducted to determine whether a new fertilizer affects the yield of tomato plants.
The procedure involves randomly assigning the new fertilizer to 20 plants and the other 20 will be assigned the current fertilizer.
Then the mean number of tomatoes produced per plant will be recorded for each fertilizer, and the difference in the sample means will be calculated.
The collected sample data will then be used to make conclusion about the population.
The researchers main aim is to determine whether the new fertilizer is effective or not, i.e. if on using the new fertilizer the yield of tomatoes increases or not.
So, the parameter under study id the difference between tow population means.
To make inferences about the experiment the researcher can construct a two-sample <em>t</em>-interval for a difference between population means. The confidence interval has a certain specific probability of including the true parameter value.
Thus, the correct option is (c).
Answer: When you divide by 100 you are essentially moving the decimal of the number two places to the left. In undoing this you would have to move the decimal of the number two places to the right.
28.003 would then turn into 2,800.3
Step-by-step explanation:
Unfortunately I cannot draw a chart on here but that is the best I can do.
I think it’s 8 ( I’m not sure )
