Temka [501]

Answer:

D. 5$

Step-by-step explanation:

So, since he wants to save up the whole year, that would be 365 days. And, he wants to collect some money after then end of each <em>week</em>, and a week is 7 days, so you'd divide 365/7. This would give you about 52 weeks he'll set aside money for United Way. Therefore, you'd divide $260/52 weeks, to get a total of $5 each week.

This figure shows △XYZ . MZ¯¯¯¯¯¯ is the angle bisector of ∠YZX . What is XM ? Enter your answer, as a decimal, in the box. unit

astraxan [27]

Answer:

Length of XM is 5.5 units.

Step-by-step explanation:

Given △XYZ where MZ is the angle bisector of ∠YZX . we have to find the length of XM.

A triangle with vertices X, Y, and Z. Side XZ is base. A line segment drawn from Z to M bisects ∠YZX into two parts ∠YZM and ∠XZM.

YZ=7 units, XZ=11 units and YM=3.5 units

By angle bisector theorem which states that an angle bisector of an angle divides the opposite side in two segments that are proportional to the another two sides of the triangle.

Hence, $\frac{YM}{MX}=\frac{YZ}{XZ}$

⇒ $\frac{3.5}{MX}=\frac{7}{11}$

⇒ MX=5.5 units.

Hence, length of XM is 5.5 units.

For f(x) = 4x + 1 and g(x) = x2 - 5, find (f - g)(x)

taurus [48]

Answer:

The value of $\frac{f}{g} (x)$ is $\dfrac{4x + 1}{x^{2} -5 }$

Step-by-step explanation:

Given as :

f(x) = 4 x + 1

g(x) = x² - 5

Let the value of $\frac{f}{g} (x)$ = A

So, According to question

$\frac{f}{g} (x)$ = $\dfrac{f(x)}{g(x)}$

Or, A = $\dfrac{4x + 1}{x^{2} -5 }$

So, The value of $\frac{f}{g} (x)$ = A = $\dfrac{4x + 1}{x^{2} -5 }$

Hence, The value of $\frac{f}{g} (x)$ is $\dfrac{4x + 1}{x^{2} -5 }$ Answer

An academic department with five faculty members—Anderson, Box, Cox, Cramer, and Fisher—must select two of its members to serve

Maru [420]

Answer:

(a) 0.10

(b) 0.70

Step-by-step explanation:

Items b and c are missing from the question:

(b) What is the probability that at least one of the two members whose name begins with C is selected?

(c) If the five faculty members have taught for 3, 6, 7, 10, and 14 years, respectively, at the university, what is the probability that the two chosen representatives have a total of at least 18 years teaching experience there?

The number of ways to select two representatives out of 5 people is given by the combination of picking two out of 5:

$n=\frac{5!}{(5-2)!2!}\\n=10\ ways$

(a) Since there is only one way for both Anderson and Box to be selected, the probability is:

$P = \frac{1}{10}=0.10$

(b) There are four ways for Cox to be selected, four ways for Cramer to be selected, and one where both are selected. The probability is:

$P =\frac{4+4-1}{10}=0.7$

(c) The only possible ways for the total of number of years to exceed 18 is by selecting: (14;6 14;7 14;10). Therefore the probability is:

$P = \frac{3}{10}=0.30$
