Answer:

50

Step-by-step explanation:

The range is 50 because the maximum number is 90 and you subtract that from 40 which gives you 50.

90= maximum

40= minimum

90-40=50

A variety of energy bar regularly sells for $1.35, but for one week they were on sale for $0.95.
TiliK225 [7]

Answer:

E) $1.05

Step-by-step explanation:

before sale: $1.35×12=$16.20

during sale: $0.95×(12×3)=$34.20

total money spent=$16.20+$34.20=$50.40

total bars bought=12+(12×3)=48

average=

\frac{50.40}{48}  = 1.05

How many tissues should the kimberly clark corporation package of kleenex contain? researchers determined that 60 tissues is the
Agata [3.3K]

Answer:

Step-by-step explanation:

For the null hypothesis,

µ = 60

For the alternative hypothesis,

h1: µ < 60

This is a left tailed test

Since the population standard deviation is not given, the distribution is a student's t.

Since n = 100,

Degrees of freedom, df = n - 1 = 100 - 1 = 99

t = (x - µ)/(s/√n)

Where

x = sample mean = 52

µ = population mean = 60

s = samples standard deviation = 22

t = (52 - 60)/(22/√100) = - 3.64

We would determine the p value using the t test calculator. It becomes

p = 0.00023

We would reject the null hypothesis if α = 0.05 > 0.00023

QUICK!!!
Svetlanka [38]

Answer:

Option B is the right choice.

Step-by-step explanation:

Given:

An are CE and an inscribed angle CBE.

Measure of inscribed angle CBE = 25 °

We have to find the measure of the arc CE.

Concept:

  • An inscribed angle is an angle with its vertex on the circle.
  • The measure of an inscribed angle is half the measure the intercepted arc.
  • Measure of inscribed angle = 1/2 × measure of intercepted arc .

To find the measure of arc CE.

⇒ \angle CBE = \frac{1}{2} \times m\ (arc\ CE)

⇒ 2\times \angle CBE = m\ (arc\ CE)

⇒ 2\times 25 = m\ (arc\ CE)

⇒ 50 = m\ (arc\ CE)

Measure of intercepted arc CE = 50 degrees.

The measure of arc CE = 50° so, option B is the right choice.
