C. 10, 80, 90.
someone pls help, i will give brainliest
Answer:
∠DOB= 48°Step-by-step explanation:
→ Angle = 180
→ [tex]n^o+108^o+2n^o=180^o[/tex]
→ [tex]3n^o+108^o=180[/tex]
→ [tex]3n^o=72^o[/tex]
→ [tex]n=72^o/3[/tex]
→ [tex]n=24[/tex]
∠DOB= 2n = 2× 24°
∠DOB= 48°

Find the area of this
irregular figure.
9 ft
[ ? ] square feet
8 ft
15 ft
26 ft
Answer:
426 ft^2.
Step-by-step explanation:
It area = area of the rectangle + area of the triangle
= 15 * 26 + 1/2 * 8 * 9
= 390 + 1/2*8*9
= 390 + 36
= 426 ft^2.
The area of the figure given is 426 ft^2.
How to find the surface area of some object?Find the area that its outer surfaces possess. Sum of all those surfaces' area is the surface area of the considered object.
Supposing that there is no direct formula available for deriving the area, we can derive the area of that region by dividing it into smaller pieces, whose area can be known directly.
Area = Area of the rectangle + Area of the triangle
Area = 15 * 26 + 1/2 * 8 * 9
Area = 390 + 1/2*8*9
Area = 390 + 36
Area = 426 ft^2.
Therefore, the area of the figure given is 426 ft^2.

A jar contains 21 brown and 19 blue marbles. A marble is drawn at random. What is the theoretical probability of drawing a blue marble? P(blue) = 63.3% P(blue) = 47.5% P(blue) = 2.5% P(blue) = 19% P(blue) = 52.5%
Answer:
The answer would be the 1st one.
Step-by-step explanation:
When you use a percentage calculator or look it up, you can shay 40 as a percent of 19 and the answer will be 47.5%. You could also divide and get your answer that way as well.

A food scientist takes a random sample of 25 cereals in order to test the claim that the mean fiber content is less than 2.5 grams. The graphs of the data and two types of hypothesis test output are provided below. Determine which output should be used and state the conclusion of this test at the 5% significance level.
Answer:
Choice A: there is insufficient evidence to conclude that the mean for the fiber content is less than 2.5 gms.
Step-by-step explanation:
From the graphs given the more appropriate is one sample t- test
One sample t- test is used and the results are
Hypothesis Test Fiber
Sample Mean 2.62
Sample St. Dev 3.492
Degrees of Freedom 24
t- test statistic 0.1718
p- value 0.5675
the critical region for this test at ∝= 0.05 is t < -1.711
There is not enough evidence to reject the null hypothesis.
Since the calculated t= 0.1718 does not fall in the critical region the null hypothesis is accepted that the mean fiber content is not less than 2.5 grams.T

Write the equation of the circle graphed below.
Answer:
(x + 2)² + (y + 2)² = 0.75²
Step-by-step explanation:
Standard form
(x - h)² + (y - k)² = r²
the center is (h, k) = (-2, -2)
the radius is r = 0.75
(x + 2)² + (y + 2)² = 0.75²
Answer:
(x + 2)^2 + (y + 2)^2 = 0.5625
Step-by-step explanation:
By looking at the graph, we can see the center of the circle is (-2, -2) and by counting the squares, the radius is 0.75.
The standard form of a circle equation is:
(x - h)^2 + (y - k)^2 = r^2
where (h, k) is the center and r is the radius.
We can substitute our values in to get:
(x + 2)^2 + (y + 2)^2 = 0.5625
