Apples are cut into 8 pieces to be shared among some children. Twenty-two bags of seven apples are used. How many pieces of appl

grigory [225]

Answer: 1232 pieces

Work Shown:

1 bag = 7 apples

22 bags = 22*7 = 154 apples

So we have 154 apples to work with in total.

Each of those apples is cut into 8 pieces, giving us 8*154 = 1232 pieces

We can write it as one single calculation to say 22*7*8 = 1232

$3, $1, $5, $2, $3, $9, $1 = $24 - $1 = $23 - $1 = $22.

$22 is the estimation of the bill when all of the amounts are rounded to the nearest dollar. The estimation is greater than the total bill which is 23 cents less than the estimation. The total on the register is reasonable and accurate.

Claudia added an equilateral triangle shape that is one inch high and one inch wide to a slide in her presentation. She clicked

mr_godi [17]

The effect of Claudia's changing the height of of the triangle from 1 inch

to 3 inches is the option;

The height of the triangle changed to three inches but the width remained 1 inch

<h3>Which option gives the effect of changing the height?</h3>

The given dimensions of the equilateral triangle Claudia added are;

Height of the triangle = 1 inch

Width of the triangle = 1 inch

The value Claudia typed in the Shape Height box = 3

Required:

What happened to the shape after she press Enter

Solution:

By entering 3 in the Shape Height box, changes the height of the

equilateral triangle to 3 inches but the width remains 1 inches

From a similar question posted online, the correct option is therefore;

The height of the triangle changed to three inches but the width remained 1 inch

<u><em>Null hypothesis:H₀:-</em></u><em> There is no significant difference between in drug resistance between the two states</em>

<u><em>Alternative Hypothesis :H₁:</em></u>

<em>There is significant difference between in drug resistance between the two states</em>

<em>B)</em>

<em>The calculated value Z = 2.7261 > 2.054 at 0.02 level of significance</em>

<em> Rejected H₀</em>

<em>There is a significant difference in drug resistance between the two states.</em>

C)

P - value = 0.0066

<em>P - value = 0.0066 < 0.02</em>

<em>D) </em>

<em>1) Reject H₀ </em>

<em>There is a significant difference in drug resistance between the two states.</em>

Step-by-step explanation:

<u><em>Step(i):-</em></u>

<em>Given first sample size n₁ = 174</em>

Suppose that, of 174 cases tested in a certain state, 11 were found to be drug-resistant.

<em>First sample proportion </em>

$p_{1} = \frac{x_{1} }{n_{1} } = \frac{11}{174} = 0.0632$

<em>Given second sample size n₂ = 375</em>

Given data Suppose also that, of 375 cases tested in another state, 7 were found to be drug-resistant

<em>Second sample proportion</em>

<em> </em> $p_{2} = \frac{x_{2} }{n_{2} } = \frac{7}{375} = 0.0186$ <em></em>

<u><em>Step(ii):-</em></u>

<u><em>Null hypothesis:H₀:-</em></u><em> There is no significant difference between in drug resistance between the two states</em>

<u><em>Alternative Hypothesis :H₁:</em></u>

<em>There is significant difference between in drug resistance between the two states</em>

<em>Test statistic</em>

<em> </em> $Z = \frac{p_{1}-p_{2} }{\sqrt{PQ(\frac{1}{n_{1} }+\frac{1}{n_{2} } ) } }$ <em></em>

<em> Where </em>

<em> </em> $P = \frac{n_{1}p_{1} +n_{2} p_{2} }{n_{1} +n_{2} }$ <em></em>

<em> </em> $P = \frac{174 (0.0632) + 375 (0.0186) }{174+375 } = \frac{17.9718}{549} = 0.0327$ <em></em>

<em> Q = 1 - P = 1 - 0.0327 = 0.9673</em>

<u><em>Step(iii):-</em></u>

<em></em>

<em> Test statistic</em>

<em> </em> $Z = \frac{p_{1}-p_{2} }{\sqrt{PQ(\frac{1}{n_{1} }+\frac{1}{n_{2} } ) } }$ <em></em>

<em> </em> $Z = \frac{0.0632-0.0186 }{\sqrt{0.0327 X 0.9673(\frac{1}{174 }+\frac{1}{375 } ) } }$ <em></em>

<em> Z = 2.7261</em>

<em> </em>

<em>Level of significance = 0.02 or 0.98</em>

<em>The z-value = 2.054</em>

<em>The calculated value Z = 2.7261 > 2.054 at 0.02 level of significance</em>

<em> Reject H₀ </em>

<em>There is a significant difference in drug resistance between the two states.</em>

<u><em>P- value </em></u>

<em>P( Z > 2.7261) = 1 - P( Z < 2.726)</em>

<em> = 1 - ( 0.5 + A (2.72))</em>

<em> = 0.5 - 0.4967</em>

<em> = 0.0033</em>

we will use two tailed test

<em>2 P( Z > 2.7261) = 2 × 0.0033</em>

<em> = 0.0066</em>

<em>P - value = 0.0066 < 0.02</em>

<em> Reject H₀ </em>

<em>There is a significant difference in drug resistance between the two states.</em>
