Simplify one or both sides by combing like terms X=8-3

Answers

Answer:

x=5

Step-by-step explanation:

All you have to do is subtract 8-3 and you get 5, which makes ur answer simplified, you cant simplify x.

Answer:

$x = 5$

Step-by-step explanation:

$x = 8 - 3$

$x = 5$

In circle F what is the measure of arc CB?

17.5
35
70
60

Answers

The inscribed angle theorem says that the angle formed by two intersecting chords of a circle (the angle A between the chords AC and AB in this case) has half the measure of the central angle subtended by the arc containing those chords (arc CB in this case). So

$m\angle BAC=\frac12m\angle BFC\implies m\angle BFC=2\cdot35^\circ=70^\circ$

Find the perimeter and area of the regular polygon. Round answers to the nearest tenth.

Answers

Answer: perimeter = 26.5

Area = 106

Step-by-step explanation:

The given polygon is an octagon. The apotherm which is the perpendicular line from the midpoint of the octagon is 8,

The formula for determining the area of a polygon is expressed as

Area = a² × n × tan 180/n

Where n represents the number of sides of the polygon.

n = 8

Therefore,

Area = 8² × 4 × tan(180/8)

Area = 256 × tan 22.5

Area = 106

The formula for determining the perimeter of a regular polygon is

P = 2 × area/apotherm

Perimeter = 2 × 106/8

Perimeter = 26.5

The test statistic of zequalsnegative 2.40 is obtained when testing the claim that less than 0.32. a. Using a significance level of alphaequals0.10, find the critical value(s). b. Should we reject Upper H 0 or should we fail to reject Upper H 0

Answers

Answer:

a) Critical value = -1.285

b) We should reject null hypothesis that the mean equals 0.32

Step-by-step explanation:

Given that the statistic of z equals negative 2.40 is obtained when testing the claim that less than 0.32

i.e. for hypotheses

$H_0: \bar = 0.32\nH_a: \bar x <0.32\n$

(one tailed test at 10% significance level)

Z critical value for 90% one tailed = -1.285

Since our test statistic is less than -1.285 we reject null hypothesis

a) Critical value = -1.285

b) We should reject null hypothesis that the mean equals 0.32

X^3 times x^? equals to x^17

what’s the missing exponent?

Answers

Answer:

Step-by-step explanation:

The applicable rule of exponents is ...

(a^b)(a^c) = a^(b+c)

You have ...

(x^3)(x^a) = x^17

x^(3+a) = x^17

Equating exponents, we get ...

3 +a = 17

a = 14

The missing exponent is 14.
