Answer:

Yes,

Step-by-step explanation:

16/22 = 0.72727272727

24/33 = 0.72727272727

When translated into decimals, they both equal 0.72 reoccurring.

x = 0.72727272727...

10x = 7.2727272...

100x = 72.727272727...

100x - x = 90x = $\frac{72}{90}$ which can be translated/simplified into $\frac{16}{22}$ and $\frac{24}{33}$

pls give brainliest if this helped !!

What force would have been applied to the bus from t=16 s to t=21 s? Assume the mass of the bus was 50 kg.

Svetllana [295]

Applying Newton's Second Law, it is found that the force, in Newtons, is given by:

$F = 10[v(21) - v(16)]$

Newton's Second Law states that Force, in Newtons, is mass times acceleration, that is:

$F = ma$

In this problem, mass of 50 kg, thus $m = 50$

Acceleration is change in velocity divided by change in time, that is:

$a = \frac{\Delta_v}{\Delta_t}$

In this problem, we don't know the velocities, but know that time is from 16s to 21s, thus:

$\Delta_t = 21 - 16 = 5$

$\Delta_v = v(21) - v(16)$

Thus, the force is given by:

$F = ma$

$F = m\frac{\Delta_v}{\Delta_t}$

$F = 50\frac{[v(21) - v(16)]}{5}$

$F = 10[v(21) - v(16)]$

A genetic experiment involving peas yielded one sample of offspring consisting of 430 green peas and 155 yellow peas. Use a 0.05

Dimas [21]

Answer:

the null and alternative hypothesis are

$H_{0}$ : p=0.24

$H_{a}$ : p≠0.24

Test statistic is 1.416.

P-Value is 0.1568

We fail to reject the null hypothesis under 0.05 significance level

At 0.05 significance we cannot say that the proportion of offspring peas will be yellow is not 0.24 (24%)

Step-by-step explanation:

Let p be the proportion of offspring peas will be yellow. Then,

$H_{0}$ : p=0.24

$H_{a}$ : p≠0.24

test statistic can be calculated as

z= $\frac{p(s)-p}{\sqrt{\frac{p*(1-p)}{N} } }$ where

p(s) is the sample proportion of yellow offspring peas ( $\frac{155}{155+430} =0.265$
p is the proportion of yellow offspring peas assumed under null hypothesis. (0.24)

N is the sample size (585)

Test statistic is z= $\frac{0.265-0.24}{\sqrt{\frac{0.24*0.76}{585} } }$ ≈ 1.416.

Using z-table, we can find that P-Value is 0.1568

We fail to reject the null hypothesis under 0.05 significance level since 0.157>0.05

We can conclude that at 0.05 significance we cannot say that the proportion of offspring peas will be yellow is not 0.24 (24%)
