Answer:

A) 5 x 0.89 and C) 5.31 x 10^0

Step-by-step explanation:

If you want two decimal places in the product, you have to multiply a number in the hundredths place and another number for a product in the hundredths. But the thing is, you have to make sure it doesn't end up in the tenth place such as 0.02 x 5 is 0.1.

So 5 x 0.89 is 4.45 and 5.31 x 10^0 is 5.31

Answer : The correct options are:

(A) 5 × 0.89

(C) 5.31 × 10⁰

(E) 3.2 × 4.3

Step-by-step explanation :

If we want two decimal places in the product then we have to multiply a number in the hundredths place and another number for a product in the hundredths.

As we are given that the following multiplication expressions. Now we have to determine the which expression have two decimal places in the product.

(A) 5 × 0.89

The multiplication of two number will be, 4.45

(B) 7.4 × 10

The multiplication of two number will be, 74.0

(C) 5.31 × 10⁰

The multiplication of two number will be, 5.31

(D) 6.1 × 3

The multiplication of two number will be, 18.3

(E) 3.2 × 4.3

The multiplication of two number will be, 13.76

From this we conclude that the expression that have two decimal places in the product are,

(A) 5 × 0.89

(E) 3.2 × 4.3

The area of a rectangular qarden is 5510 m(squared)

seraphim [82]

Answer:

A=L*W

let a be area, l be length and w be width

we know a is 5510m

we know w is 58m

so sub in what you know and rearrange to solve for L

5510=58L

5510/58=L

L=95m

therefore the length is 95m.

Write a statement that indicates that the triangles to each pair are congruent

Pachacha [2.7K]

Answer:

Triangles are congruent because all the corresponding sides and interior angles are congruent.

Step-by-step explanation:

In ΔWXY and ΔBCD

Given Sides are congruent:

$WX \cong BC$

$XY \cong CD$

$YW \cong DB$

Also,

Angles are congruent i,e:

$\angle W \cong \angle B$

$\angle X \cong \angle C$

$\angle Y \cong \angle D$

By congruence statement: If two sides in one triangle are congruent to two sides of a second triangle, and also if the included angles are congruent, then those triangles are congruent.

$\triangle WXY \cong \triangle CBD$

Therefore, we can say the two triangles WXY and BCD are congruent because every corresponding side are of equal length and every corresponding angle has the same measure.

For Exercises 51–60, use the following information:

Leni [432]

Answer:

Step-by-step explanation:

We assume your "natural numbers" are <em>positive integers</em>. (Some authors also include zero.)

n(B) = 5

n(U) = 20

n(B') = 20 -5 = 15

A new city Mayor would like to determine the proportion of community voters who are ages 18 to 20 years. He has heard it is 10%.

Keith_Richards [23]

Answer: He should reject the null hypothesis.

Step-by-step explanation: When using P-Values to decide if you accept or not the alternative hypothesis, compare the p-value with the chosen significance level (α).

In the Mayor's survey:

p-value = 0.04

α = 5% or 0.05

If the p-value is less than α, reject the null hypothesis and accept the alternative. If p-value is greater than or equals α, fail to reject the null hypothesis and don't accept the alternative.

Analysing the Mayor's survey:

p-value = 0.04 < α = 0.05

In conclusion, the Mayor should reject the null hypothesis and accept that the proportion of voters who are aged 18 to 20 is not equal to 10%, i.e., accept the alternative hypothesis: $H_{a}$ : p≠0.10
