5. If median =137 and mean = 137.05, then find the value of mode. (2marks)

NeTakaya

Answer:- 136.9

Step-by-step explanation:

3median=2mean+mode

3(137)=2(137.05)+mode

411=274.1+mode

411-274.1=mode

mode=136.9

Solve the equation with rational exponents. (x minus 1 )Superscript 2 divided by 3 Baseline equals 64

Katarina [22]

Answer:

$x=513 \Rightarrow S=\{513\}$

Step-by-step explanation:

1) Rewriting for the sake of clarity:

$(x-1)^{\frac{2}{3}}=64$

2) To solve it, we need to turn the rational exponent equal to 1 via exponent rule of product. Multiplying 2/3 by its reciprocal 3/2 we get 1, since this is an equality we need to do it on the other side.

$(x-1)^{\frac{2}{3}}=64\\\\((x-1)^{\frac{2}{3}}]^{\frac{3}{2}}=(64)^{\frac{3}{2}}\\(x-1)=\sqrt{64^{3}}\\x-1+1=512+1\\x=513$

If a number n has exactly 7 divisors, how many divisors does n squared have?

Anna [14]

A number $n=p_1^{a_1}\cdot p_2^{a_2}\cdot\ldots\cdot p_k^{a_k}$ , where $p_k$ are distinct prime numbers, has $(a_1+1)(a_2+1)\cdot\ldots\cdot(a_k+1)$ divisors.

We know that $n$ has 7 divisors. 7 is a prime number, so among the numbers $a_1+1,a_2+1,\ldots,a_k+1$ there is only one that is equal to 7.

So,
$a_k+1=7\\
a_k=6$

That means $n=p^6$ where $p$ is a prime number.
$n^2=(p^6)^2=p^{12}$ , therefore the $n^2$ has $12+1=13$ divisors.
