The product of two whole numbers is 196 and their sum is 35. what are the two numbers
Svet_ta [12734]
A) The product of x and y equals 196. Thus, A) x is equal to 196 divided by y.

B) The sum of x and y is 35. By substituting A) into B), we have
B) 196 divided by y plus y equals 35. Multiplying both sides by y yields
B) 196 plus y squared equals 35y. This results in B) y squared minus 35y plus 196 equals 0.
Therefore, the solutions are X1 = 28 and X2 = 7.

f Khan had an army of 10,000 soldiers at the lowest level, how many men in total were under him in his organization? (b) If Khan
babunello [11817]

Cette question est incomplète, la question complète est;

Gengis Khan organisait ses hommes en groupes de 10 soldats dirigés par un « leader de 10 ». Dix « leaders de 10 » étaient sous un « leader de 100 ». Dix « leaders de 100 » étaient sous un « leader de 1 000 ».

(a) Si Khan avait une armée de 10 000 soldats au niveau le plus bas, combien d'hommes en tout étaient sous son commandement dans son organisation?

(b) Si Khan avait une armée de 5 763 soldats au niveau le plus bas, combien d'hommes en tout étaient sous son commandement dans son organisation?

On suppose que les groupes de 10 doivent contenir 10 si possible, mais qu'un groupe à chaque niveau peut avoir besoin de témoigner moins

Réponse:

a) = 11110 soldats

b = 6404 soldats

Explication étape par étape:

Étant donné que Khan a disposé ses hommes en groupes de 10 sous un « leader de 10 », dix « leaders de 10 » étaient supervisés par un « leader de 100 », et dix « leaders de 100 » étaient dirigés par un « leader de 1000 »

alors

a) Si Khan avait une armée de 10 000 soldats au niveau le plus bas, combien d'hommes au total étaient sous son organisation?

MAINTENANT

Nombre de soldats = 10 000

Rang le plus bas (soldat) = 10000

troisième plus haut (leader de 10) = 10000/10 = 1000

deuxième le plus élevé (leader de 100) = 1000/10 = 100

Le plus haut (Leader de 1000) = 100/10 = 10

donc le total = 10000 + 1000 + 100 + 10 = 11110 soldats

b) Si Khan avait une armée de 5 763 soldats au rang le plus bas, combien d'hommes au total étaient sous son commandement dans son organisation? On suppose que les groupes de 10 doivent contenir 10 si possible, mais qu'un groupe à chaque niveau peut avoir besoin de témoigner moins

MAINTENANT

Nombre de soldats = 5 763

Rang le plus bas (soldat) = 5763

troisième plus haut (leader de 10) = 5763/10 = 576.3 = 577 (nombre entier requis pour un humain)

deuxième le plus élevé (leader de 100) = 577/10 = 57.7 = 58

Le plus haut (Leader de 1000) = 58/10 = 5.8 = 6

donc le total = 5763 + 577 + 58 + 6 = 6404 soldats

cookies are sold singly or in packages of 7 or 21. with this packaging how many ways can you buy 42 cookies?
Svet_ta [12734]
You can acquire 42 cookies through 12 different combinations. The first method involves purchasing 2 packs of 21 (21x2 = 42). The second consists of acquiring 1 pack of 21 alongside 3 packs of 7 (21 + 3x7 = 42). The third way is to buy 1 pack of 21 and 21 individual cookies (21 + 21 = 42). The fourth option combines 1 pack of 21, 1 pack of 7, and 14 single cookies (21 + 7 + 14 = 42). The fifth strategy includes 1 pack of 21, 2 packs of 7, and 7 individual cookies (21 + 14 + 7 = 42). The sixth way is to opt for 6 packs of 7 (7x6 = 42). The seventh option is to purchase 5 packs of 7 along with 7 individual cookies (7x5 + 7 = 42). For the eighth method, you can buy 4 packs of 7 and 14 single cookies (7x4 + 14 = 42). The ninth way is to get 3 packs of 7 with 21 single cookies (7x3 + 21 = 42). The tenth consists of acquiring 2 packs of 7 plus 28 individual cookies (7x2 + 28 = 42). The eleventh strategy involves 1 pack of 7 and 35 single cookies (7 + 35 = 42). Lastly, the twelfth method is simply buying 42 individual cookies (42 = 42).

A 2012 Gallup survey of a random sample of 1014 American adults indicates that American families spend on average $151 per week
tester [12383]

Answer:

a.[144;158]$

b. The parameter being estimated is the average weekly food expenses of American families.

Step-by-step explanation:

Hello!

The variable studied here represents "Weekly food expenses incurred by an American family"($)

From a sample of n=1014 American families, the sample mean is x[bar]=$151

It is indicated that for the 95% confidence interval, the margin of error is ±$7

a.

The estimated confidence interval for the population mean is formed as "estimator ± margin of error." In a Standard Normal distribution, the confidence interval formula is:

[x[bar]±Z_{\alpha/2}*(δ/√n)]

For the provided sample, we have:

[151±7]

The lower limit equates to 144$

The upper limit amounts to 158$

b.

The parameter being contemplated is the average weekly food expenses of American families.

The confidence level for this interval reflects the likelihood that if 100 such intervals were constructed, approximately 95 would encompass the true value of the population mean we aim to estimate.

Wishing you a wonderful day!
