A 6 inch-tall plant grew 3/4 of an inch week and twice as much the following week. How tall is the plant now?

The plant is 8 1/4 inches tall because you multiply 3/4 and 2 which equals 1 1/2 then you add 6 and 3/5 and 1 1/2 which equals 8 1/4 inches

8.25 inches once you multiply the 3/4 by 2 and add that and also add the 3/4 from the previous week you’ll get your answer

Place decimal points in 34, 4, and 417 so that the sum of the three numbers is 7.97.

KIM [24]

3.4+0.4+4.17=7.97 you just have to try different combinations of different numbers with the decimals.

You are conducting a study to see if the accuracy rate for fingerprint identification is significantly different from 0.4. You u

Ludmilka [50]

Answer:

Calculated Z -value = 2 < 2.326 at 0.02 level of significance

Null hypothesis is accepted

The accuracy rate for fingerprint identification is not significantly different from 0.4.

b)

P-value of this sample = 0.0455

Step-by-step explanation:

Step(i):-

Given sample size 'n' = 298

Sample proportion

$p^{-} = \frac{x}{n} = \frac{136}{298} = 0.456$

Population proportion

p = 0.4

Null hypothesis :-

The accuracy rate for fingerprint identification is not significantly different from 0.4

H₀: p=0.4

Alternative Hypothesis :-

The accuracy rate for fingerprint identification is significantly different from 0.4

H₁: p≠0.4

Step(ii):-

Test statistic

$Z = \frac{p^{-} -P}{\sqrt{\frac{P Q}{n} } }$

$Z = \frac{0.456-0.4}{\sqrt{\frac{0.4 X 0.6}{298} } }$

Z = 2

Given level of significance α=0.02

critical value Z = 2.326

Calculated Z -value = 2 < 2.326 at 0.02 level of significance

Null hypothesis is accepted

The accuracy rate for fingerprint identification is not significantly different from 0.4.

P- value

P( Z>2) = 1- P( Z <2)

= 1 - ( 0.5 - A(2)

= 0.5 - 0.4772

= 0.0228

Given two tailed test = 2 ×P( Z >2)

= 2 × 0.0228

= 0.0456

The p-value is 0.0456
