Barky's animal shelter has a total of 15
Chihuahuas and Yorkies. There are four
times as many Chihuahuas as Yorkies.
Using c for Chihuahuas and y for Yorkies,
determine which equation may be
used to represent this situation.
c=4+y
y=4+c
y=4c
c=4y
Answers
Answer:
c = 4y
Step-by-step explanation:
Are there more, Chihuahuas or Yorkies?
Does the word 'times' mean add, subtract, multiply or divide?
The way I look at it, there are more Chihuahuas and 'times' means multiply. Do you agree?
Therefore, I need to multiply 4 times the no. of Yorkies to get the no. of Chihuahuas
So, c = 4y
Now, I don't see an equation in the list to choose from. So, I don't know what to do from here. I am guessing that c = 4y is what you want.

(7x + 2) feet
(2x + 7) feet
(2x − 7) feet
(7x − 2) feet
Answers
Answer:
(2x + 7) feet
Step-by-step explanation:
I'm guessing the expression there is
4x² + 28x + 49
4x² +14x +14x +49
Factorize
2x ( 2x + 7) +7( 2x + 7)
(2x + 7)²
Area = (side)1
One side is (2x +7)

In a survey of 706 parents with kids 4 to 8 years old. 346 say that they know their state booster seat law. Construct a 90% confidence interval for the population proportion.
Answers
Answer:
(0.46, 0.52)
Step-by-step explanation:
The formula for Confidence Interval with Proportion
CI = p ± z × √p(1 - p)/n
Where
p = Proportion = x/n
x = 346
n = 706
p = 346/706
p = 0.49
z = z score of Confidence Interval 90% = 1.645
Therefore:
CI = 0.49 ± 1.645 × √0.49(1 - 0.49)/706
CI = 0.49 ± 1.645 × √0.49 × 0.51/706
CI = 0.49 ± 1.645 × 0.0188139843
CI = 0.49 ± 0.0309490042
Hence:
Confidence Interval is
0.49 - 0.0309490042
= 0.4590509958
≈ 0.46
0.49 + 0.0309490042
= 0.5209490042
≈ 0.52
Therefore , the confidence interval of the population proportion is
(0.46, 0.52)

In triangle PQR, angle P and R are complementary angles where cos P =(0.3) what is the measure in degrees of angle R round to the nearest tenth
Answers
Answer:
[tex]R = 17.5[/tex]
Step-by-step explanation:
Given
P and R are complementary
[tex]Cos\ P =0.3[/tex]
Required
Find the measure of R
[tex]Cos\ P =0.3[/tex]
Take arccos of both sides
[tex]P = cos^{-1}(0.3)[/tex]
[tex]P = 72.5[/tex]
Since P and R are complementary, then:
[tex]P + R = 90[/tex]
Make R the subject
[tex]R = 90 - P[/tex]
Substitute values for P
[tex]R = 90 - 72.5[/tex]
[tex]R = 17.5[/tex]
