Without calculating the answer for 5 1/5 * 2/5 be larger or smaller than 5 1/5

solniwko [45]

Answer:

Evidently, without the calculating 5 1/5 times 2/5 would be larger than 5 1/5 since you are already gonna multiply 2/5 and that would make it larger.

Hope this helps!

Branliest would be appreciated :DD

A recent poll of 700 people who work indoors found that 278 smoke. if the researchers want to be 98% confident of their results

Mice21 [21]

Answer:

We are given:

$\hat{p}=\frac{278}{700}=0.397$

$z_{\frac{0.02}{2}}=2.33$ is the critical value at 0.02 significance level

$E=0.035$ is the margin of error

Therefore, the required sample size is:

$n=\hat{p}(1-\hat{p}) \left(\frac{z_{\frac{0.02}{2}} }{E} \right )^{2}$

$=0.397(1-0.397) \left( \frac{2.33}{0.035} \right)^2$

$=0.239391 \times 4431.755102$

$=1060.922286 \approx 1061$

Therefore, the required sample size n = 1061

The diameter of a truck tire is 22inches Approximately how fat will the truck have traveled after 5 rotations of these tires

kvasek [131]

Answer:

The truck have travelled 345.5 inches after 5 rotations of the tires

Step-by-step explanation:

Given:

Diameter of the tyre= 22 inches

Number of rotations= 5

To find:

Distance travelled after 5 rotations=?

Solution:

We have given with diameter,

So let radius be r

r= $\frac{diameter}{2}$

$r=\frac{22}{2}$

r=11 inches

The distance covered by one rotation is given by circumference

Circumference = $2\pi r$

Substituting the values, we get

Circumference = $2\times\pi\times r$

Circumference = $2\times\pi\times 11$

Circumference = $2\times\3.14\times 11$

Circumference = $6.28\times 11$

Circumference = 69.11

Now for 5 rotation,

Distance travelled = $5\times(\text{circumference value})$

Distance travelled = $5\times(69.11)$

The truck will travel 345.5 inches.
