Answer:
let the number be y
4(y-7)=48
y-7=48/4
y-7=12
y=12+7=19
I would appreciate if my answer is chosen as a brainliest answer
Height of a trapezoid:
h = 5 · sin 80° = 5 · 0.985 = 4.924
x = 5 · cos 80° = 5 · 0.17365 = 0.868
7 - x = 7 - 0.868 = 6.132
By the Pythagorean theorem:
d² = 6.132² + 4.924²
d² = 37.6 + 24.25
d² = 61.85
d = √61.85
d = 7.86 ≈ 8

Answer with explanation:
Data set Showing number of times seventh period class attended a summer camp since first grade:
3, 1, 0, 4, 1,⇒⇒Mean =1.8
4, 2, 3, 0, 5,⇒⇒Mean =2.8
0, 1 , 1, 2, 0,⇒⇒Mean =0.8
4, 1, 4, 4, 2,⇒⇒Mean =3
3, 2, 0, 1, 4⇒⇒Mean =2
⇒≡Mean of a Data set is sum of all the variate in data set divided by total number of Variate in the data set.
Range of the sample Means of a data set is difference between Maximum value of variate in the data set and Minimum value of Variate in Data set.
Maximum Value in the sample mean = 3
Minimum Value in the sample mean = 0.8
⇒Range = Maximum value of mean - Minimum value of mean
= 3 - 0.8
= 2.2
⇒≡None of the option given, matches with the value of range Calculated.
4/20 students say S.S. is their favorite
75% say PE is their favorite
you need to get them in the same conditions, one is fraction, and one is percent
4/20= ?% /100 4 __ cross multiply on paper
20 100
4x100= 400/20=20
20% say s.s. is their favorite
20% is smaller than 75%
expresson: 4
20< 75%
Did you try using 2 for x?
