Given:

Given that the quadrilateral ABCD is inscribed in the circle.

The measure of ∠A is (14z - 7)°

The measure of ∠C is (8z)°

The measure of ∠D is (10z)°

We need to determine the measures of ∠A, ∠B, ∠C and ∠D

Value of z:

We know the property that the opposite angles of a quadrilateral inscribed in a circle are supplementary.

Thus, we have;

$\angle A+ \angle C=180^{\circ}$

Substituting the values, we have;

$14z-7+8z=180$

$22z-7=180$

$22z=187$

$z=8.5$

Thus, the value of z is 8.5

Measure of ∠A:

The measure of ∠A can be determined by substituting the value of z.

Thus, we have;

$\angle A=14(8.5)-7$

$\angle A=119-7$

$\angle A=112^{\circ}$

Thus, the measure of ∠A is 112°

Measure of ∠C:

The measure of ∠C can be determined by substituting the value of z.

Thus, we have;

$\angle C=8(8.5)$

$\angle C =68^{\circ}$

Thus, the measure of ∠C is 68°

Measure of ∠D:

The measure of ∠D can be determined by substituting the value of z.

Thus, we have;

$\angle D=10(8.5)$

$\angle D=85^{\circ}$

Thus, the measure of ∠D is 85°

Measure of ∠B:

The angles B and D are supplementary.

Thus, we have;

$\angle B+ \angle D=180^{\circ}$

Substituting the values, we get;

$\angle B+ 85^{\circ}=180^{\circ}$

$\angle B=95^{\circ}$

Thus, the measure of ∠B is 95°

What is the distance between (-7, -2) and (13,-23)

Zolol [24]

Step-by-step explanation:

here,

x1=-7

x2=13

y1=-2

y2=-23

$\boxed{\blue{ distance=\sqrt{(y2-y1)^2+(x2-x2)^2} }}$ ⠀

= $\tt{\sqrt{(-23-(-2))^2+(13-(-7))^2}}$ ⠀

= $\tt{\sqrt{(-21)^2+(20)^2} }$ ⠀

= $\tt{\sqrt{ 441+400} }$ ⠀

= $\tt{\sqrt{841} }$ ⠀

= $\tt{ 29 }$ ⠀

So,

the distance between (-7, -2) and (13,-23)=29

Because of her work schedule, Molly Kay plans to take classes at 8:00, 10:00, and 11:00. Five courses that fit her program are o

pychu [463]

Answer: There are 90 different schedules are possible for Molly Kay.

Step-by-step explanation:

Since we have given that

Three time scheduled at 8:00, 10:00, 11:00.

Number of courses offer at 8:00 = 5

Number of courses offer at 10:00 = 9

Number of courses offer at 11:00 = 2

So, the number of different schedules are possible for Molly Kay is given by

$^{5}C_1\times ^9C_1\times ^2C_1\\\\=5\times 9\times 2\\\\=45\times 2\\\\=90$

Hence, there are 90 different schedules are possible for Molly Kay.

3) in clinical trials of Nasonex, 3774 adult and adolescent allergy patients (ages 12 and older) were randomly

Nonamiya [84]

Fun. I prefer Oxymetazoline.

For the control group we have a headache probability of

c = 368/1671 = .220

For the experimental group we have a headache probability of

e = 494/2013 = .245

The observed difference is

d = e - c = .025

The variance of the difference is

s² = c(1-c)/n₁ + e(1-e)/n₂

so the standard deviation is

$s=\sqrt{.220(1-.220)/1671 + .245(1-.245)/2013} = 0.0139$

We get a t statistic on the difference of

t = d/s = .025/.0139 = 1.79

We're interested in the one sided test, P(d > 0). We have enough dfs to assume normality. We look up in the standard normal table

P(z < 1.79) = .96327

p = P(z > 1.79) = 1 - .96327 = 0.037 = 3.7%

Answer: That's less that 10% so we have evidence to conclude that headaches are significantly greater in the experimental group.
