The HCF of two numbers is 175. The LCM of these two numbers is 12600. Both numbers are greater than their HCF. Find the two numb
Serjik [45]

Answer:

Hello,

Answer : 1400 and 1575

Step-by-step explanation:

Let's say a and b the ywo numbers

HCF(a,b)=a\vee b=175=5^2*7\\LCM(a,b)=a\wedge b=12600\\\\a*b=(a\vee b)*(a\wedge b)=(2^3*3^2*5^2*7)*(5^2*7)=2^3*3^2*(5^2*7^2)^2\\\\Both\ numbers\ are\ greater\ than\ their HCF\\a=175*k_1\\b=175*k_2\\\\k_1=2^3\ and\ k_2=3^2\\\\a=175*2^3=1400\\b=175*3^2=1575\\\\

Use technology to find the​ P-value for the hypothesis test described below.
Masteriza [31]

Answer:

The p-value is 0.175

Step-by-step explanation:

We have the null hypothesis H_{0}: \mu = 18 and the alternative hypothesis H_{1}: \mu \neq 18 (two-tailed alternative). Because the sample size is n = 17 and the test statistic is t=-1.421, we know that this last value comes from a t distribution with n-1=17-1=16 degrees of freedom. Therefore, the p-value is given by 2P(T < -1.421) because the p-value is the probability of getting a value as extreme as the observed value and because of the simmetry of the t distribution. Here, T has a t distribution with 16 df and we are using the t distribution because the sample size is small. So, 2P(T < -1.421) = 0.1745

A new shopping mall records 120 total shoppers on their first day of business. Each day after that, the
KiRa [710]

\boldsymbol{\mathbf{Answer}}

\boldsymbol{\mathbf{213\,shoppers\, will\, visit\,on \, first\, seventh\, day}}

\boldsymbol{\mathbf{Step-by-step explanation}}

Let, No of shoppers on first day = a

No of shoppers on second day = b

Similarly till seventh day,

Therfore shoppers on seventh day=

a + b + c + d + e + f + g

As mentioned ,number of shoppers is 10% more than the number of shoppers the day before. i.e we can understand that a to g all are 1.1 times bigger than the previous letter.

That means all are in geometric series.

We know the formula for sum of geometric series is,

=\boldsymbol{\mathbf{\sum {a}\times{r^{(n-1)}}}}

\boldsymbol{\mathbf{a \, is\, first\, value}}

\boldsymbol{\mathbf{r \, is\, multiplication\, factor\, value}}

\boldsymbol{\mathbf{n \, is\, no\, items\, in\, series}}

That is,

a = 120

r = 1.1

n = 7

=\sum {120}\times{1.1^{(7-1)}}

={120}\times{1.7715}  

= 212.58

Approximately

\boldsymbol{\mathbf{=\, 213 \,shoppers \,will\, be \,there\, on \,seventh \,day.}}
