Tina does not have enough rope to decorate the frame

Step-by-step explanation:

Tina wants to decorate a rectangular picture frame

The width of the frame is 18 inches
The length of the frame is 14 inches
She has 4 feet rope

We want to know if she has enough rope or not to decorate the frame

∵ The frame is in the shape of the rectangle

- The length of the rope must be equal the perimeter of the frame

∵ The perimeter of a rectangle = 2 length + 2 width

∵ The length = 14 inches

∵ The width = 18 inches

∴ The perimeter of the frame = 2(14) + 2(18) = 28 + 36 = 64 inches

∵ The length of the rope is 4 feet

∵ 1 foot = 12 inches

∴ The length of the rope = 4 × 12 = 48 inches

∵ 48 < 64

∴ The length of the rope is less than the perimeter of the frame

∴ Tina does not have enough rope

Tina does not have enough rope to decorate the frame

QveST [7]

Answer:

We conclude that the mean nicotine content is less than 31.7 milligrams for this brand of cigarette.

Step-by-step explanation:

We are given the following in the question:

Population mean, μ = 31.7 milligrams

Sample mean, $\bar{x}$ = 28.5 milligrams

Sample size, n = 9

Alpha, α = 0.05

Sample standard deviation, s = 2.8 milligrams

First, we design the null and the alternate hypothesis

$H_{0}: \mu = 31.7\text{ milligrams}\\H_A: \mu < 31.7\text{ milligrams}$

We use One-tailed t test to perform this hypothesis.

Formula:

$t_{stat} = \displaystyle\frac{\bar{x} - \mu}{\frac{s}{\sqrt{n}} }$

Putting all the values, we have

$t_{stat} = \displaystyle\frac{28.5 - 31.7}{\frac{2.8}{\sqrt{9}} } = -3.429$

Now, $t_{critical} \text{ at 0.05 level of significance, 8 degree of freedom } = -1.860$

Since,

$t_{stat} < t_{critical}$

We fail to accept the null hypothesis and accept the alternate hypothesis. We conclude that the mean nicotine content is less than 31.7 milligrams for this brand of cigarette.

While testing a new vaccine, a lab technician noticed that the number of bacteria reduced by half every minute. How long does it

son4ous [18]

To start, find your equation, n=3000(.5)^t, n being your number of bacteria and t being your time. Now plug in 375 for n and solve for t, 375=3000(.5)^t, .125=.5^t, $t=log_{.5} .125=3$ . This means your answer is 3 minutes. To check it, plug it into your equation. n=3000(.5)^t=3000(.125)=375

Four sisters bought a present for their mother. They received a 10% discount on the original price of the gift. After the discou

Orlov [11]

Answer:

$40

Step-by-step explanation:

x is the original price of the gift

(10% of x) is the value of the discount

(10% of x) = 10/100 . x = 0.1 x

0.1 x is the value of the discount

x - (10% of x) is what was paid, after the discount

x - 0.1 x = 0.9 x

0.9 x is what was paid

4 children paid $9/each

4 times $9 = $36

$36 is the total amount that was paid by the children

$36 = 0.9 x

$36 / 0.9 = x

x = $36 / 0.9 = 360 / 9

x = 40
