What is a triangle?It is a two dimensional figure which has three sides and the sum of the three angles is equal to 180 degrees.
We have,
BY = YC = 50/2 = 25
BX = XA = 42/2 = 21
Now,
XY is parallel to AC.
BX/XY = BA/AC
21/30 = 42/AC
1/30 = 2/AC

anova can be used to test whether more than two population variances are different. group of answer choices true fals
To determine whether there are differences between more than two population variances, utilise anova is True
What is Anova?
A statistical technique called analysis of variance, or ANOVA, divides observed variance data into various components for use in further testing. When there are three or more data groups, a one-way ANOVA is used to find out how the dependent and independent variables are related.
Concept:
One-way ANOVAs are typically used when there are three or more categorical independent groups, although they can also be employed when there are only two groups (but an independent-samples t-test is more commonly used for two groups)
A statistical procedure called Analysis of Variance (ANOVA) is used to examine variations between the means (or averages) of several groups. It is used in a variety of situations to discover whether there are any differences between the means of various groups.
To determine how the values of two categorical factors affect the mean of a quantitative variable, a two-way ANOVA is utilised. When you wish to determine how two independent factors interact with one another to effect a dependent variable, use a two-way ANOVA.
The absence of a difference in means is always the null hypothesis in an ANOVA. The alternative or research hypothesis, which is typically expressed in words rather than mathematical symbols, asserts that the means are not all equal. The research hypothesis involves any difference in means, such as when all four means are different from one another, one mean differs from the other three, two means differ, and so on. All scenarios other than the equality of all means described in the null hypothesis are covered by the alternative hypothesis, as it was previously illustrated.

What is the nature of roots of 2x² 3x 5 0?
The nature of the roots of 2x² 3x 5 0 are imaginary, as it is not possible to solve for real numbers.
To solve this equation, we first factor out the coefficients (2 and 5). Factoring out 2 gives us x² + 1.5x + 5 = 0. After that, we solve for x using the quadratic formula:
x
= -1.5 ± √(-1.5² - 4(1)(5)) / 2(1). This is reduced to x = -1.5 9.5 / 2, an imaginary number that cannot be solved using real values. This indicates that the equation's roots are fictitious.

find the length of the arc of the curve from point p to point q. y = 1 2 x2, p −7, 49 2 , q 7, 49 2
The length of the arc of the curve from point p to point q is 14.
The length of the arc is calculated by using the differentiation of the curve expression.
Here we have given that expression y = 1/2 x²
And we need to find the length of the arc from the point P to Point Q.
In order to find the length we have to extract the x values from the given point then we get,
(x1, x2) = (-7, 7)
Here we have the curve of the arc as,
=> y = 1/2 x²
Now, we have to differentiate the expression to find the solution,
=> length of arc = ∫₋₇⁷1/2 x²
=> length of arc = 1/2 ∫₋₇⁷ x²
=> length of arc = 1/2 [2x]₋₇⁷
When we apply the values on x, then we get,
=> length of arc = 1/2 [2(7) - 2(-7)]
=> length of arc = 1/2 [28]
Therefore, the length is 14.

Percent of the daily value for saturated fat provided would be 48%
What is Percent Daily Value?
Daily Values are recommendations that specify the amounts of certain nutrients that the average person should obtain each day. Daily Values are only a general guide because they are calculated for the average person who consumes a total of 2,000 calories a day.
If the total saturated fat for the meal is 95 grams, this is equal to 95,000 milligrams of saturated fat.
To find the percent daily value for saturated fat from this meal, we can use the following formula:
percent daily value = (total saturated fat / recommended daily intake) * 100
= (95,000 / 2000) * 100
= 47.5
Rounded to the nearest whole number, the percent daily value for saturated fat from this meal is approximately 48%
