Mathematics
1 answer:
Dafna1 [17]3 years ago
5 0

Answer:

A

Step-by-step explanation:

● first one:

The diagonals of a rhombus are perpendicular to each others wich means that they form four right angles.

STP is one of them so this statement is true.

● second one:

If ST and PT were equal this would be a square not a rhombus.

● third one:

If SPQ was a right angle, this woukd be a square.

● fourth one:

Again if the diagonals SQ and PR were equal, this would be a square.

Charlotte and Riley walked 6/10 of a mile to school one day, and then after school they walked 3/8 of a mile to the store. From
IrinaK [193]

Answer: The girls walked 1\dfrac38 miles.

Step-by-step explanation:

Given:  Distance from home to school = \dfrac{6}{10} mile

Distance from school to store = \dfrac38 mile

Distance from store to home = \dfrac25 miles

Total distance = \dfrac6{10}+\dfrac38+\dfrac25

= \dfrac{6\times4+3\times5+2\times8}{40}   [L.C.M.(10,8,5)=40]

= \dfrac{24+15+16}{40}

= \dfrac{55}{40}

= \dfrac{11}{8}=1\dfrac38  miles

Hence, The girls walked 1\dfrac38 miles.

6 Using data from 1988 for houses sold in Andover, Massachusetts, from Kiel and McClain (1995),
Nimfa-mama [501]

The study of explanatory or independent differences based on the dependent variable is a simple statistical method. The correlation between two variables is researched in which only the explanatory variable of them would be present, and the further discussion can be defined as follows:

For point (i):

  • The log(distances) seem to be optimistic, and their valuation is 0.312, which also means that the cost of a house will rise even as the distance increases.
  • In this, the certainly is what everybody expects the better the house from the sewage treatment is from a hygienic viewpoint.

For point (ii):

  • In this regard, we cannot use straightforward regression, even as non-biased price estimation might not even be provided.
  • The price-distance relationship here is not so much linear.

For point (iii):

  • Several factors influence the house's price, the biggest contributor is house length, market nearness or public areas, number of rooms, etc.
  • Thus the only influence is not the mere distance from the incinerator. It's one of the factors affecting housing pricing.
  • The proximity of markets and places can be connected to the distance from the crematorium.
  • However, factors such as house size and the number of stories aren't related to the distance from the incineration plant.

True or false and why: if a and b are irrational, then a^b is irrational
FrozenT [24]

False


b could be the logarithm of a rational number to the base a. For example,

b=\log_\pi{(4)}   will be irrational, but π^b = 4, a rational number

Use the distributive property.
(3/8)*(16x-24)=(3/8)(16x)-(3/8)(24)
16x*3/8=48x/8=6x
24*3/8=72/8=9
6x+9
