Answer: both boys started with 14 marbles sani’s sister took 4 marbles and gave them to carter

Step-by-step explanation:

If they started with the same amount then sanis sister took some and gave them to carter and made it to where sani now has 18 and carter has 10 it’s simple math.

10 to 18 is 8 in between so split 8 in half and you get 4 so you count down 4 from 18 and you get 14.

There for both boys started with 14 marbles.

In XYZ, mX=90 and mY=30.In TUV,mU= 30 and mV=60. Which is true about the two triangles? XYZ=TUV, XYZ= VUT,No congruency statemen

Flauer [41]

Answer:

No congruency statement can be made because the side length are unknown.

Step-by-step explanation:

The sum of the measures of all interior angles in a triangle is always 180°.

In triangle XYZ,

$m\angle X=90^{\circ}\\ \\m\angle Y=30^{\circ},$

then

$m\angle X+m\angle Y+m\angle Z=180^{\circ}\Rightarrow m\angle Z=180^{\circ}-90^{\circ}-30^{\circ}=60^{\circ}$

In triangle TUV,

$m\angle U=30^{\circ}\\\\m\angle V=60^{\circ},$

then

$m\angle T+m\angle U+m\angle V=180^{\circ}\Rightarrow m\angle T=180^{\circ}-30^{\circ}-60^{\circ}=90^{\circ}$

We have two triangles with congruent angles but we have no information about side lengths. Therefore, can not be made because the side length are unknown. Correct option is last option.

Answer:

The population is the set of all the elements. And the sample is a subset of the population.

Step-by-step explanation:

The population is the set of all the elements. And the sample is a subset of the population.

The sample is used to make conclusions regarding the population.

A poll is conducted from the target population to determine the general opinions of the individuals of that population.

The basic method of polling is to select a few thousand individuals from the population and ask their opinions on a certain subject.

The poll will result usually in two values, the proportion of individual in favor and the proportion of individual not in favor.

Consider the example below.

The polling done to determine the favorability of the new brand of tea. The polling was done using a few hundred members of the tea drinking community of a country. The poll resulted as follows:

In favor = 72%

Not in favor = 28%

The population is the entire tea drinking community of a country.

In this case the sample consist of few 100 people of the tea drinking community of a country.

Using it's concept, it is found that the odds that the winner shops in the store 4 or more times a week are given by: 9:41.

<h3>What is the odd of an event?</h3>

It is given by the <u>number of desired outcomes divided by the number of non-desired outcomes</u>.

Researching the problem on the internet, it is found that 18% of the winners shop in the store 4 or more times a week, while 82% do not, hence:

18:82 = 9:41

The odds that the winner shops in the store 4 or more times a week are given by: 9:41.
