Answer:
<u>Use cross-multiplication to solve these</u>
- 1) 6/2 = 4/p ⇒ 6p = 4*2 ⇒ p = 8/6 ⇒ p = 4/3
- 2) 4/k = 8/2 ⇒ 8k = 2*4 ⇒ k = 8/8 ⇒ k = 1
- 3) n/4 = 8/7 ⇒ n = 4*8/7 ⇒ n = 32/7
- 4) 5/3 = x/4 ⇒ x = 4*5/3 ⇒ x = 20/3
Answer:
4
Step-by-step explanation:
2+2-2+4÷2
we go through
P- parentheses
E- exponents
M- multiplication
D- division
A- addition
S- subtraction
also note that we read it from left to right becaue × is not more important than ÷ and same goes to + and -
First step
2+2-2+(4÷2) --> 2+2-2+2
then
2+2-2+2 --> 4-2+2
then
4-2+2 --> 2+2
finally
2+2=4
Complete Question
The alternative hypothesis is
and it is found the statistic is 1.04 Test the claim with 5% significance level. is the test left right or two tailed and what is the p value
Answer:
This a right tailed test
The p-value is p-value = 0.14917
Step-by-step explanation:
From the question we are told that
The alternative hypothesis is ![H_a : p > 0.9](https://tex.z-dn.net/?f=H_a%20%3A%20%20p%20%20%3E%200.9)
The test statistics is ![z = 1.04](https://tex.z-dn.net/?f=z%20%3D%20%201.04)
The level of significance is ![\alpha = 0.05](https://tex.z-dn.net/?f=%5Calpha%20%20%3D%20%200.05)
Generally this a right tailed test because from the alternative hypothesis p > 0.9 i.e due to the greater than sign signifying that test will be focusing on the right tail of the normal curve
From the z table the area under the normal curve to the right corresponding to 1.04 is
P( Z> 1.04 ) = 0.14917
Generally the p-value is mathematically represented as
p-value = P( Z> 1.04 ) = 0.14917
Answer:
6
Step-by-step explanation:
The given expression is ![36^{\frac{1}{2}}](https://tex.z-dn.net/?f=36%5E%7B%5Cfrac%7B1%7D%7B2%7D%7D)
We rewrite using property of exponents to get;
![(6^2)^{\frac{1}{2}}=(6)^{2\times \frac{1}{2}}](https://tex.z-dn.net/?f=%286%5E2%29%5E%7B%5Cfrac%7B1%7D%7B2%7D%7D%3D%286%29%5E%7B2%5Ctimes%20%5Cfrac%7B1%7D%7B2%7D%7D)
This gives
![(6)^{2\times \frac{1}{2}}=6^1=6](https://tex.z-dn.net/?f=%286%29%5E%7B2%5Ctimes%20%5Cfrac%7B1%7D%7B2%7D%7D%3D6%5E1%3D6)
Or simplify;
![36^{\frac{1}{2} }=\sqrt{36} =6](https://tex.z-dn.net/?f=36%5E%7B%5Cfrac%7B1%7D%7B2%7D%20%7D%3D%5Csqrt%7B36%7D%20%3D6)
Answer:
112
