ASAPcan someone help find the surface area pls?

Answer»

Surface area of first figure as shown in 1ST PICTURE:

LENGTH = 6cm

breadth = 3cm

height= 2cm

Surface area = 2(lb+ bh + hl)

=2(6×3+3×2+2×6)

=2× 36

= 72cm^2

NOW WE FIND AREA OF SECOND FIGURE AS SHOWN IN PICTURE 2:

length = 3cm

breadth=1cm

height=2cm

Surface Area = 2(lb+ bh + hl)

=2(3×1+1×2+2×3)

22.	9.Rao’s Finance claims that less than 50% of adults in Suva have a will. A will is a legal document that sets forth your wishes regarding the distribution of your property and the care of any minor children. If you die without a will, those wishes may not be carried out. To substantiate the claim, a random sample of 1000 adults showed that 450 of them have a will. A. At the 5% significance level, can you conclude that the percentage of people who have a will than 50%? B. What is the Type I error in part A? What is the probability of making this error? C. What would your decision be in part A if the probability of making a Type I error were zero? Explain
Answer» (A) We conclude that the percentage of people who have a will is less than 50% at 5% significance level. (B) Type I error is that we conclude that the percentage of people who have a will is less than 50% but in actual it was equal to 50%. Probability of making this error is 5%. (C) If the probability of making a Type I error were zero in part A, then we will definitely be able to reject our null hypothesis. Step-by-step explanation: We are GIVEN that Rao’s Finance claims that less than 50% of adults in Suva have a will. To substantiate the claim, a random sample of 1000 adults showed that 450 of them have a will. Let p = percentage of people who have a will. So, Null Hypothesis, $H_0$ : p = 50% {means that the percentage of people who have a will is equal to 50%} Alternate Hypothesis, $H_A$ : p < 50% {means that the percentage of people who have a will is less than 50%} The test statistics that would be USED here One-sample z-test for proportions; T.S. = $\frac{\hat p-p}{\sqrt{\frac{p(1-p)}{n} } }$ ~ N(0,1) where, $\hat p$ = sample proportion of people who have a will = $\frac{450}{1000}$ = 0.45 n = sample of adults = 1000 So, the test statistics = $\frac{0.45-0.50}{\sqrt{\frac{0.50(1-0.50)}{1000} } }$ = -3.162 The value of z test statistic is -3.162. (A) Now, at 5% significance level the z table gives critical value of -1.645 for left-tailed test. Since our test statistic is less than the critical value of z as -3.162 < -1.645, so we have sufficient evidence to reject our null hypothesis as it will fall in the rejection region due to which we reject our null hypothesis. Therefore, we conclude that the percentage of people who have a will is less than 50%. (B) Type I error states that Probability of rejecting null hypothesis given the fact that it was true or in other words; Probability of rejecting a true hypothesis. SO, according to our question Type I error is that we conclude that the percentage of people who have a will is less than 50% but in actual it was equal to 50%. Probability of making this error = Level of significance = 5% (C) If the probability of making a Type I error were zero in part A, then we will definitely be able to reject our null hypothesis and conclude that the percentage of people who have a will is less than 50%.

9.Rao’s Finance claims that less than 50% of adults in Suva have a will. A will is a legal document that sets forth your wishes regarding the distribution of your property and the care of any minor children. If you die without a will, those wishes may not be carried out. To substantiate the claim, a random sample of 1000 adults showed that 450 of them have a will. A. At the 5% significance level, can you conclude that the percentage of people who have a will than 50%? B. What is the Type I error in part A? What is the probability of making this error? C. What would your decision be in part A if the probability of making a Type I error were zero? Explain

Answer»

(A) We conclude that the percentage of people who have a will is less than 50% at 5% significance level.

(B) Type I error is that we conclude that the percentage of people who have a will is less than 50% but in actual it was equal to 50%.

Probability of making this error is 5%.

(C) If the probability of making a Type I error were zero in part A, then we will definitely be able to reject our null hypothesis.

Step-by-step explanation:

We are GIVEN that Rao’s Finance claims that less than 50% of adults in Suva have a will.

To substantiate the claim, a random sample of 1000 adults showed that 450 of them have a will.

Let p = percentage of people who have a will.

So, Null Hypothesis, $H_0$ : p = 50% {means that the percentage of people who have a will is equal to 50%}

Alternate Hypothesis, $H_A$ : p < 50% {means that the percentage of people who have a will is less than 50%}

The test statistics that would be USED here One-sample z-test for proportions;

T.S. = $\frac{\hat p-p}{\sqrt{\frac{p(1-p)}{n} } }$ ~ N(0,1)

where, $\hat p$ = sample proportion of people who have a will = $\frac{450}{1000}$ = 0.45

n = sample of adults = 1000

So, the test statistics = $\frac{0.45-0.50}{\sqrt{\frac{0.50(1-0.50)}{1000} } }$

= -3.162

The value of z test statistic is -3.162.

(A) Now, at 5% significance level the z table gives critical value of -1.645 for left-tailed test.

Since our test statistic is less than the critical value of z as -3.162 < -1.645, so we have sufficient evidence to reject our null hypothesis as it will fall in the rejection region due to which we reject our null hypothesis.

Therefore, we conclude that the percentage of people who have a will is less than 50%.

(B) Type I error states that Probability of rejecting null hypothesis given the fact that it was true or in other words; Probability of rejecting a true hypothesis.

SO, according to our question Type I error is that we conclude that the percentage of people who have a will is less than 50% but in actual it was equal to 50%.

Probability of making this error = Level of significance = 5%

(C) If the probability of making a Type I error were zero in part A, then we will definitely be able to reject our null hypothesis and conclude that the percentage of people who have a will is less than 50%.

Prove that root over 2 is an irrational number

Answer»

Suppose √2=p/q and √2 is a RATIONAL NUMBER

2=p^2/q^2

2q^2=p^2

As 2 divides 2q^2 , 2 divides p^2 , 2 divides p

p/2=m

p=2m

(2m)^2=p^2

(2m)^2=2q^2

2m^2=q^2

As 2 divides 2m^2 , 2 divides q^2 , 2 divides q

Thus p and q have a common factor 2.But this contradicts p and q have no common FACTORS(except 1).Hence our assumption is wrong.√2 is not a rational number.√2 is a irrational number

Answer» Question :- What is the common name of water soluble bases? Answer :- The common name of water soluble bases is Alkali. ________________________ More Info :- The group 1 of periodic table consists of Alkali metals. They have same chemical PROPERTIES as they are in the same group. They are called alkali metals because when they REACT with water, they form strong bases which can neutralize acids. They are very reactive and are not found in free state. Since it's a base, the pH is more than 7. They are extremely reactive, and are stored in oil to prevent their reaction with atmosphere. Common Alkali metals :- Sodium Hydroxide, Calcium CARBONATE etc.

If 9th term from the end of an A.P is 12th term form the beginning, then the no. of term isWho so ever will give answer fastest I will mark his answer as brainliest.

Answer»

Answer:

Step-by-step explanation:

GIVEN A.P

3,8,13,...…..,253

first term of this A.P a1=3

second term of this A.P a2=8

common difference d=a2−a1=8−3=5

the NTH term of an A.P is given by

an=a1+(n−1)d

an=3+(n−1)5

an=3+5n−5

an=−2+5n…..eq(1)

first calculate number of terms(n) in this A.P

put an=253 the last term of A.P in above eq(1)

253=−2+5n

5n=253+2

n=5255

⟹n=51

hence this A.P CONTAINS 51terms

for calculating 12th term from the END means (51−11)th term from starting of A.P

hence we have to calculate 40th term of this A.P

so put n=40 in eq(1)

a40=−2+5×40

a40=−2+200

a40=198

hence 12th term of from the end of this A.P is 198
