Answer:

3x+1

Step-by-step explanation:

you first have x(your unknown variable)

Then you multiply x by 3 to get 33x you write it like this because 3×x would be confusing.

After you have 3x you then need to add 1 and therefore your new equation is 3x+1

Divide 132kg in a ratio of 3:3:5

skad [1K]

You have to add 3+3+5.
It equals 11.
Then divide 132 by 11.
It equals 12.
Then you have to put it into the ratio, so you multiply each number by 12.
So the ratio is 36:36:60

Riya is applying mulch to her garden. she applies it at a rate of 250 , 000 cm 3 250,000 cm 3 250, comma, 000, start text, space

Tatiana [17]

The rate in

$\frac{ {m}^{3} }{ {m}^{2} } \: is \:0.25\frac{ {m}^{3} }{ {m}^{2} }$

<h3>How to find rate is riya applying mulch in m^3/m^2 ?</h3>

given that riya applies it at a rate of 250,000 cm^3 of mulch for every m^2 of garden space.

we already know that 1m = 100cm.

so, each side of this cube is 100cm in length.

so, $100 \times 100 \times 100 \: {cm}^{3} \: in \: {m}^{3}$

To find what is the volume in cubic metres.

$\frac{250000}{10000000} = \frac{1}{4} = 0.25 \frac{ {m}^{3} }{ { m}^{2} }$

so, the rate is $0.25 \frac{ {m}^{3} }{ {m}^{2} }$

An experiment was conducted to compare the wearing qualities of three types of paint (A, B, and C) when subjected to the abrasiv

MaRussiya [10]

Answer:

A) H0: mean of A= mean of B= mean of C

H1: all means are unequal

B) 3.48194

C) 0.04515

D) H0 is accepted. There is significant difference among mean hours after which visibile abrasion is observed for each type of paint

Step-by-step explanation:

A) Here Anova test will be used as we are comparing three groups

B) mean of A= 229.6, SD of A= 158.1962, SE of A= 50.026

mean of B= 309.9 , SD of B= 147.8742, SE of B= 46.7619

mean of C= 427.8, SD of C= 196.8179, SE of C= 62.2393

overall mean= 322.43

degrees of freedom between groups= 3-1=2

degrees of freeddom of error= total number of observations - number of groups= 30-3= 27

total degrees of freedom= total number of samples-1= 30-1 =29

Sum of squares between groups=∑ sample size of group×(individual group mean- over all mean)²

=198772.4667

mean of sum of squares between groups= sum of squares between groups/ (number of groups -1)

= 198772.4667/2

sum of squares of error=∑∑ (individual observation of group- group mean)²

= 770670.9223

mean sum of squares of erros= sum of squares of error/(total number of samples-number of groups)

= 770670.92/27

= 28543.38

F- stat= mean sum of squares between groups/ mean sum of squares of error

F stat= 3.48194

C) p- value= 0.04515

D) since F-stat is greater than p- value, null hypothesis is rejected

from F distribution table

Please show work for both problems

sukhopar [10]

(1) The value of x is 25

(2) The measure of ∠CBD is 60°

Explanation:

(1) The given two angles are vertical angles. Since, vertical angles are equal, we can add the two angles to determine the value of x.

Thus, we have,

$5x+15=6x-10$

Subtracting 5x from both sides, we have

$15=x-10$

Adding 10 to both sides , we have,

$25=x$

Thus, the value of x is 25.

(2) It is given that the measure of ∠ABC = (x+7)° and ∠CBD = (2x+14)°

Since, these two angles are supplementary angles and supplementary angles add upto 90°

Thus, we have,

$2x+14+x+7=90$

Simplifying, we get,

$3x+21=90$

$3x=69$

$x=23$

Thus, substituting the value of x in ∠CBD = (2x+14)° to determine its value.

$2x+14=2(23)+14=46+14=60$

Thus, the measure of ∠CBD is 60°
