Answer:

4500 gr

Step-by-step explanation:

4.5 kg equals some number (n) times one gram. Solve this for n:

4.5 kg = n(1 gr)

Recall that 1 kg = 1000 gr. Because of this, the equation above becomes

4.5 kg (4.5)(1000 gr)

n = --------------- or ------------------- or 4500 gr

1000 gr 1 gr

Lena is 10 years old. She asks her dad how old he is. He tells her that the lcm of their ages is 14 times the hcf of their ages.

strojnjashka [21]

Answer:

Step-by-step explanation:

Let x represent the HCF of the ages. Then we can have ax = 10 represent Lena's age, and bx can represent her dad's age.

The LCM will be abx = 14x, so we have ab = 14.

Factors of 14 are 1·14 and 2·7. Since the ratio of ages is between 30/10 = 3 and 45/10 = 4.5, we must have b/a in that range. This will be the case for ...

a=2, b=7

For a=2 and ax=10, we have x=5.

The dad's age is bx = 7·5 = 35.

krok68 [10]

Answer:

The answer is "(0.461 , 7.206)"

Step-by-step explanation:

In the given question some information is missing, that is data. so, the correct answer to this question can be defined as follows:

UnLogged:

$x_1=17.500\\s_1=3.529\\n_1=12$

Logged:

$x_2=13.667\\ s_2=4.500\\n_2=9\\$

formula of std error:

$\ std \ error =\sqrt{\frac{s_1^2}{n_1}+\frac{s_2^2}{n_2}}$

$=\sqrt{\frac{3.529^2}{12}+\frac{4.500^2}{9}}\\\\=\sqrt{\frac{3.529^2\times 3+4.500^2\times 4}{36}}\\\\=1.8133$

Point differential estimation = $x_1-x _2$

$= 17.500-13.667\\=3.833$

For 90 percent t= 1.860 Cl & 8 df

error of margin E = $t\times \ std \ error$

$= 1.860 \times 1.8133\\= 3.373$

Lower bound =mean difference -E=0.461

Upper bound = mean difference+ E=7.206

In the above 90% confidence interval were the population mean= (0.461 , 7.206)
